Chapter 3  Wiring of Inverter
3.1 Connection of the Product and Peripheral Devices

Fig.3-1 Connection diagram of the product and peripheral devices
3.2 Description of Peripheral Devices for Main Circuit
Circuit breaker The capacity of the circuit breaker shall be 1.5 ~ 2 time of the rated current of the inverter.
The time features of the circuit breaker shall fully consider the time features of the inverter overload protection.
Leakage circuit breaker Because the inverter output is the high-frequency pulse, there will be high-frequency leakage current. Special leakage circuit breaker shall be used when installing

leakage circuit breaker at the input end of the inverter.
It is suggested that B type leakage circuit breaker be used, and the leakage current value shall be set as 300mA.
Contactor Frequent open and close of contactor will cause inverter failure, so the highest frequency for the open and close of contactor shall not exceed 10 times/min.
When braking resistor is used, to void the overtemperature damage of the braking resistor, thermal protection relay with braking resistor overtemperature detection shall be installed to disconnect the

contactor at the contact control power side of the thermal protection relay.
Input AC reactor
or DC reactor The inverter power supply capacity is more than 600kVA or 10 times of the inverter capacity.
If there is switch type reactive-load compensation capacitor or load with silicon control at the same power node, there will be high peak current flowing into input power circuit, causing the damage

of the rectifier components.
When the voltage unbalancedness of the three-phase power supply of the inverter exceeds 3%, the rectifier component will be damaged.
It is required that the input power factor of the inverter shall be higher than 90%.
When the above situations occur, install the AC reactor at the input end of the inverter or DC reactor to the DC reactor terminal.
Input noise filter The noise input from the power end to the inverter and output from the inverter to the power end can be reduced.
Thermal protection relay Although the inverter has motor overload protection function, when one inverter drives two or more motors or multi-pole motors, to prevent the motor overtemperature

failure, thermal protection relay shall be installed between the inverter and each motor, and the motor overload protection parameter P9.16 shall be set as “2” (motor protection disabled).
Output noise filter When the output end of the inverter is connected with noise filter, the conduction and radiation interference can be reduced.
Output AC reactor When the cable connecting the inverter and the motor is longer than 100m, it is suggested to install AC output reactor to suppress the high-frequency oscillation to avoid the

damage to motor insulation, large leakage current and frequent inverter protective action.

3.6 Attention for Main Circuit Wiring
3.6.1 Power Supply Wiring
It is forbidden to connect the power cable to the inverter output terminal, otherwise, the internal components of the inverter will be damaged.
To facilitate the input side overcurrent protection and power failure maintenance, the inverter shall connect to the power supply through the circuit breaker or leakage circuit breaker and contactor.
Please confirm that the power supply phases, rated voltage are consistent with that of the nameplate, otherwise, the inverter may be damaged.
3.6.2 Motor Wiring
It is forbidden to short circuit or ground the inverter output terminal, otherwise the internal components of the inverter will be damaged.
Avoid short circuit the output cable and the inverter enclosure, otherwise there exists the danger of electric shock.
It is forbidden to connect the output terminal of the inverter to the capacitor or LC/RC noise filter with phase lead, otherwise, the internal components of the inverter may be damaged.
When contactor is installed between the inverter and the motor, it is forbidden to switch on/off the contactor during the running of the inverter, otherwise, there will be large current flowing into the

inverter, triggering the inverter protection action.
Length of cable between the inverter and motor
If the cable between the inverter and the motor is too long, the higher harmonic leakage current of the output end will cause adverse impact on the inverter and the peripheral devices. It is suggested

that when the motor cable is longer than 100m, output AC reactor be installed. Refer to the following table for the carrier frequency setting.
Length of cable between the inverter and motor Less than 50m Less than 100 m More than 100m
Carrier frequency (PA.00) Less than 15kHz Less than 10kHz Less than 5kHz
3.6.3 Grounding Wiring
The inverter will produce leakage current. The higher the carrier frequency is, the larger the leakage current will be. The leakage current of the inverter system is more than 3.5mA, and the specific

value of the leakage current is determined by the use conditions. To ensure the safety, the inverter and the motor must be grounded.
The grounding resistance shall be less than 10ohm. For the grounding wire diameter requirement, refer to 3.3 lectotype of main circuit peripheral devices.
Do not share grounding wire with the welding machine and other power equipment.
In the applications with more than 2 inverters, keep the grounding wire from forming a loop.

3.6.4 Countermeasures for Conduction and Radiation Interference

Fig.3-4 Noise current illustration
When the input noise filter is installed, the wire connecting the filter to the inverter input power end shall be as short as possible.
The filter enclosure and mounting cabinet shall be reliably connected in large area to reduce the back flow impedance of the noise current Ig.
The wire connecting the inverter and the motor shall be as short as possible. The motor cable adopts 4-core cable, with the grounding end grounded at the inverter side, the other end connected to

the motor enclosure. The motor cable shall be sleeved into the metal tube.
The input power wire and output motor wire shall be kept away from each other as long as possible.
The equipment and signal cables vulnerable to influence shall be kept far away from the inverter.
Key signal cables shall adopt shielding cable. It is suggested that the shielding layer shall be grounded with 360-degree grounding method and sleeved into the metal tube. The signal cable shall be

kept far away from the inverter input wire and output motor wire. If the signal cable must cross the input wire and output motor wire, they shall be kept orthogonal.
When analog voltage and current signals are adopted for remote frequency setting, twinning shielding cable shall be used. The shielding layer shall be connected to the grounding terminal PE of the

inverter, and the signal cable shall be no longer than 50m.
The wires of the control circuit terminals RA/RB/RC and other control circuit terminals shall be separately routed.
It is forbidden to short circuit the shielding layer and other signal cables or equipment.
When the inverter is connected to the inductive load equipment (e.g. electromagnetic contactor, relay and solenoid valve), surge suppressor must be installed on the load equipment coil, as shown in

Fig.3-5.

Chapter 6  Parameter Description
6.1 Basic Function Parameter (Group P0)

This function is used to prevent the irrelevant personnel from inquiring and changing the parameters, so as to protect the safety of the inverter parameters.
0000: No password protection: All the parameters in Zone P can be inquired and changed (If P0.01=1, the change to parameters is disabled), and no password is set upon inverter delivery.
Set password:
Input four digits as user password, and press PRG key for confirmation. Repeat this operation once.
Change password:
Press PRG key to enter the password verification status, and 0.0.0.0. is displayed. Input correct password, and it enters parameter editing status. Select P0.00 (parameter P0.00 displayed as 0000). Input

new password and press PRG key for confirmation. Set the same password for P0.00 twice.
When “P.Set” is displayed, the new password is successfully set.
Cancel password:
Press PRG key to enter the password verification status, and 0.0.0.0. is displayed. Input correct user password to enter the parameter editing status, check if P0.00 is 0000. Press PRG key for confirmation,

and set P0.00=0000 again, and then “P.Clr” is displayed and the password is cancelled.
Note: For the method for activating the password, refer to 4.5 password operation.


This function is used to set the modification authority and initialization level of the parameters.
0: All the parameters are allowed for modification.
1: All the parameters are disallowed for modification.
2: Restore all the parameters in zone P to leave-factory setting.
3. Restore all the parameters in zone P except for the motor parameters (group P9) to leave-factory setting.
4: Restore all the P zone parameters and A zone parameters (user’s customized function code display/hide zone) to leave-factory values.
5: Restore all the user parameters except for d group to leave-factory values.
Note: After the parameters are initialized, the password set by the user will be automatically reset.


Set this function, and the operation panel will display the function code parameters according to the actual need of the user to improve the work efficiency.
0: Basic menu mode: The operation panel can display all the parameters.
1: Fast menu mode: The operation panel only displays the fast parameters defined by the manufacturer. When the basic functions of the inverter are used, this menu mode shall be set.
　2: Menu mode of non-leave-factory value function code: The operation panel only displays the parameters different from the leave-factory values.
When the technical personnel perform onsite maintenance, to quickly view the parameters set by the user and detect the failure, this mode can be used.
After the inverter commissioning is completed, to conveniently record and inquire the modified parameters, this mode can be set.
　3： Menu mode of last changed 10 function codes: When the inverter has abnormal operation or it is necessary to inquire the commissioning parameters, the last changed 10 parameters can be

inquired by setting this menu mode. When the leave-factory parameters are recovered, the record of the last changed 10 function codes will also be cleared.
Note:
Both P0.00 and P0.02 are visible in all the menu display modes for the convenience of menu mode switching.
Press ESC key and hold for over 5 seconds, it will restore to basic menu mode, and P0.02 is automatically restored to 0.
In non-basic menu mode, the >> key cannot be used to switch the function zone code and group number. The current menu mode will be displayed after pressing the >> key for several times.


This function is used to set the control operation mode of the inverter. 0 ~ 3 indicates vector control 1, 4 ~ 7 indicates vector control 2.
Vector control 1 without encoder speed feedback:
0: Process open loop control: It is applicable to most applications, including the application of one inverter driving one motor and the application of one inverter driving multiple motors (the motors

are in the same work conditions).
1: Analog value feedback process close loop control: It is applicable to applications with general requirement of speed control precision. The feedback analog can represent such parameters as

temperature, pressure and humidity. For the reference and feedback setting of the analog feedback process close loop control, refer to P1.02~P1.07 function description. For the setting of the process

PID close loop parameters, refer to Group P8 function code description.
AI1 and AI2 terminal input specification: 0~10V or 0~20mA.
AI3 terminal input specification: -10~10V;
X7/DI terminal input specification: 0~ maximum input pulse frequency P5.10.
2: Single-phase pulse feedback process close loop control: It is applicable to applications with higher speed control precision, and pulse encoder shall be installed at the motor end or mechanical

　3：Composite control: The composite control of process open loop and analog feedback closed loop is suitable for special applications.
As for the set frequency of the inverter, if it is necessary to made fine tuning on another physical parameter in the system in addition to the open loop setting, closed loop adjustment can be made to

this physical parameter. The adjustment result will be added to the open loop frequency reference of the inverter, so as to ensure the constancy of the physical parameter through speed control. Refer

to the description of the open loop and closed loop composite operation relation calculation parameter P1.08.

This function is applicable to the frequency reference of open loop control mode, such as vector control 1, vector control 2. For the speed reference of process close loop control mode, refer to

function code of Group P1.

Note: When P0.04=4, the X7/DI terminal function must be set to pulse frequency DI input (P5.06=5) .

Three different operating command reference modes can be selected for the inverter.
0: Operation panel mode: Perform the Run, Stop, Forward/reverse operation of the inverter through the RUN, STOP/RST, FWD/REV buttons of the operation panel.
1: Terminal mode: Perform the Run, Stop, Forward/reverse operation of the inverter by defining the multi-functional terminals X1~X7. Refer to the description of P5.00~P5.06 and P5.11.

Note: This function code is invalid under terminal running command reference mode, and the running direction is controlled by terminal command.

　　
This function can set the speed and stability in the duration from acceleration to constant speed after the startup of the inverter, or from constant deceleration to stop.
Acceleration time 0: The time that the inverter accelerate from 0 frequency to maximum frequency.
Deceleration time 0: The time that the inverter accelerate from maximum frequency to 0 frequency.
S curve time: The time for adding curve segment to improve the smoothness of the start and ending section during the acceleration and deceleration, P0.10. S curve time is applicable to the belt

conveyer that carries fragile materials or applications requiring smooth speed adjustment.

Fig.6-1 Acceleration/deceleration time and S curve
When P0.10 is set as 0, it indicates that there is no S curve time, and the acceleration and deceleration is in linear mode.
Acceleration time =P0.08×set frequency/P0.11; deceleration time =P0.09×set frequency/ P0.11.
When P0.10 is set as a non-zero value, it indicates that there is S curve time, and the acceleration and deceleration adopts S curve mode.
S curve acceleration/deceleration time = acceleration/deceleration time +S curve time.
As shown in Fig.6-1, curve 1 is the curve representing the acceleration/deceleration in linear mode, curve 2 is the curve representing the acceleration/deceleration in S curve mode.
Curves 1 and 2 corresponding to the same setting frequency. The actual acceleration/deceleration time of curve 2 is longer than that of curve 1 by the time set by P0.10.
　　Note:
The S curve acceleration/deceleration setting is also available for acceleration times 1, 2 and 3 (P4.09~P4.14) , with the principle same as above.
It is appropriate when the ratio between the S curve time and the acceleration/deceleration time is 1/5.


The maximum output frequency fmax is the allowable maximum output frequency of the inverter.
The maximum output voltage Vmax is the output voltage when the inverter is in basic operating frequency. When standard AC motor is used, it corresponds to the motor rated voltage. Refer to motor

nameplate.
The frequency upper limit fH and frequency lower limit fL are the maximum and minimum operating frequency of the motor set according to the production process requirement by the user during

the use.
The basic operating frequency fb is the minimum frequency corresponding to the maximum output voltage of the inverter. When standard AC motor is used, it corresponds to the rated frequency of

the motor. Refer to the motor nameplate.

so as to ensure the normal operation of the motor.
　Note:

When P0.16 is set as 0.0, and P4.00 is set as 0 (linear V/F curve), the automatic torque boost mode is enable; when P4.00 is set as a non-zero value, the automatic torque increase mode is disabled.

Note: When the corresponding frequency of the combination value fcom exceeds the upper or lower limit of the frequency, the output frequency will be restricted to the upper or lower limit.

In the analog feedback close loop system, if there are main reference and auxiliary reference, the main reference value can be digital voltage, analog and pulse, the auxiliary reference value can be

analog and pulse.
The analog feedback close loop control main reference mode P1.02 may be selected as follows:

0: Main + auxiliary; 1: Main - auxiliary; 2: Auxiliary -50%; 3: Main+ auxiliary-50%; 4: Max; 5: Min
The main reference and auxiliary reference calculation function for close loop reference is the same as the main reference and auxiliary reference calculation function for open loop reference. For

details, refer to the description of P1.01.
Note: Under the analog feedback close loop control mode, the analog main reference, analog auxiliary reference, analog main feedback and analog auxiliary feedback cannot be set at the same

channel.

In the analog feedback close loop system, the main feedback and auxiliary feedback can be analog or pulse.
The main feedback and auxiliary feedback calculation function for process close loop feedback is the same as the main reference and auxiliary reference calculation function for process close loop

Note:
Under the analog feedback close loop control mode, the analog main reference, analog auxiliary reference, analog main feedback and analog auxiliary feedback cannot be set at the same channel.
When the process close loop analog feedback mode is DI, the pulse will be translated into analog (0~10V) as feedback:
　Analog = pulse/maximum pulse input frequency P5.10×10V.



　　This function definition is similar to that of P1.01. The process open loop composite reference fcom in this function definition can be treated as main reference, the frequency output of closed

loop PID adjustment fPID can be treated as auxiliary reference, and fFIN can be treated as composite reference.

6.4 Startup/stop Parameter (Group P3)


Different startup modes can be adopted for different applications.
0: The inverter begins to run from the startup frequency P3.03 and accelerates to the setting frequency after the startup frequency retention time P3.04. If the motor is still rotating upon the startup of

the inverter, the motor will be automatically decelerated to low speed before the acceleration.
1: DC current is injected first to perform DC magnetizing and DC braking on the motor. The volume and time for the DC injection are set by P3.01 and P3.02.  After the DC injection time expires, the

inverter begins to run from the startup frequency P3.03 and accelerates to the setting frequency after the startup frequency retention time P3.04.
2: Flying startup.
The inverter will automatically identify the speed of the motor and directly start from the identified frequency. The current and voltage are smooth without any impact during the startup.
Note: During the DC current supply, the operation panel displays “-dc-”.
　　

P3.01 sets the volume of the DC injection current, which is indicated in a percentage of the rated current of the inverter. Upon variable torque load: 0.0~90.0%.
P3.02 sets the action time of the DC injection.



The inverter begins to run from the startup frequency P3.03 and accelerates according to acceleration time after the startup frequency retention time P3.04.
Note: For the heavy-load startup applications, it will facilitate the startup if the startup frequency and retention time are properly set.


Different stop modes can be adopted for different applications.
0: Decelerate to stop according to the deceleration time.
1: The inverter locks the output and the motor coast to stop.
2: Decelerate to stop according to the deceleration time. When the frequency is lower than the DC braking initial frequency P3.06, inject the DC braking current P3.07, and the DC braking time is

determined by P3.08.
Note: During the DC braking, the operation panel displays “-dc-”.
　　



P3.06 sets the initial frequency at the beginning of DC braking current injection during the shutdown
P3.07 sets the DC braking current value. This value is presented as the percentage of the rated current of the inverter. It ranges from 0.0 ~ 90.0% upon variable torque load.
P3.08 sets the action time of the DC braking current.




For some production equipment, reverse operation may cause equipment damage. This function can be used to prevent reverse operation. P3.09 is set to forbid reverse operation by default upon

delivery.
When the motor rotation direction is opposite to the required direction of the equipment, the wire connection of any two terminals at the output side the inverter can be interchanged so that the

forward rotation direction of the equipment is consistent with the forward rotation direction defined by the inverter.
Set P3.10 to realize the waiting time for the zero-crossing of rotation speed when the inverter switches from forward rotation to reverse rotation (or from reverse rotation to forward rotation).

P3.11 is the frequency set for jog operation.
Jog acceleration time P3.12: The time from zero to maximum frequency.
Jog deceleration time P3.13: The time from maximum frequency to zero.
When the inverter is in standby status, it can adopt jog operation. The jog operation command may come from the operation panel, multi-functional terminal or host computer.
6.5 Multi-section Parameter (Group P4)

　It is to determine the different V/F curves under vector control 1 mode.

Fig. 6-12 V/F curve                         Fig.6-13 Multi-section V/F curve
P4.00=0: Applicable to the constant torque load situation, refer to the straight line in Fig.6-12.
P4.00=1: Self-defined curve of the user, applicable to sectional constant torque load, refer to Fig.6-13.
In Fig.6-13:F0<F1<F2<F3<fb        fb is the motor basic operating frequency P0.15
V0≤V1≤V2≤V3≤100%    V0, V1, V2, V3 are indicated in the percentage of the maximum output frequency P0.12.
P4.00=2~6: Applicable to the variable torque loads such as fan and pump. When P4.00 is set to 2~6, it corresponds to 1.2-power, 1.4-power, 1.6-power, 1.8-power and second power, as shown in Fig.6

-12. The second power curve is for water supply, and the 1.2-power to 1.8-power curves are for the liquid loads of other media. Proper curve can be selected according to the actual situation.

In addition to the above acceleration time 0 (P0.08) and deceleration time 0 (P0.09) , three groups of acceleration/deceleration time (acceleration/deceleration time 1, acceleration/deceleration time

2, acceleration/deceleration time 3) can be defined. Different acceleration/deceleration time can be selected in different terminal status by defining the multi-functional terminal X

(acceleration/deceleration time selection function: 13~14). The meaning of the three groups of acceleration/deceleration time is the same as P0.08 and P0.09.
                                                      
It can be used as the process open loop frequency reference or analog feedback close loop digital reference.  Different digital voltage reference is selected in different terminal status by defining the

multi-functional terminal X (multi-section analog input terminals 1~3). ON means that the terminal is enabled, OFF means that the terminal is disabled.

Note: Upon process open loop operation, if the input terminal function sets the multi-section digital voltage and multi-section frequency simultaneously, the multi-section frequency will have priority.

Upon analog feedback operation, the multi-section digital voltage reference is in priority to other reference modes.

It can be used as process open loop frequency reference. Different multi-section frequency reference can be selected in different terminal status by defining the multi-functional terminal X (multi-

section frequency terminals 1~4). ON means that the terminal is enabled, OFF means that the terminal is disabled.
Note: Upon open loop operation, if the input terminal function sets the multi-section digital voltage and multi-section frequency simultaneously, the multi-section frequency has the highest priority.

6.9 Process PID Close Loop Parameters (Group P8)

Fig. 6-30 Schematic diagram for PID

The current control operation mode P0.03 shall be determined before determining the process close loop reference value.
When the current control operation mode is analog feedback process close loop (P0.03=1, 3, 5 and 7), if P1.02 is set to “0”, it may determine the reference value of the close loop by P8.00. If P1.02 is

non-zero value, it determine the reference value of the close loop by the analog value and pulse frequency selected in P1.02.
When the current control operation mode is single-phase pulse feedback process close loop (P0.03=2 and 6), it may determine the reference value of the close loop. In addition, when the single-

phase pulse feedback process close loop is employed, it needs to use an pulse encoder and set the number of single-phase pulses per rotation for the encoder according to the encoder model

(P8.02)so as to determine the close-loop feedback value indicated by the signal feedback by the single-phase pulse.
　　Note:
The signal feedback by the single-phase pulse must be connected to X7/DI terminal and this terminal shall be set to “47: Single-Phase Pulse Input. of single-phase pulse feedback process close loop

control.
In the analog value feedback close loop mode, if P1.02 is set to “0”, it can use multi-section digital voltage reference to implement the multi-section reference function of the close loop. Refer to

P4.15 ~ P4.21 for details.

As shown in Fig.6-30 PID Schematic Diagram, the higher the Kp value is, the faster the response is, but if the Kp value is too high, it may easily generate oscillation and the deviation cannot be

eliminated completely. It can use Ki to eliminate the residual deviation. The higher the Ki value is, the faster the response of the inverter to the deviation change, but it may easily generate oscillation

if the Ki value is too high. If the system has frequent feedback to the jump, it needs to use Kd because Kd can respond to the deviation change between the system feedback and the reference

quickly. The higher the Kd value is, the faster the response is, but it may easily generate oscillation if the value is too high.


This function is used to set the sampling cycle of the feedback signal. The lower this parameter value is, the faster the response of the system to the deviation between the reference and the feedback,

but if the sampling cycle is too fast, the associate requirement for the system PID gain adjustment will be higher, which may result in system oscillation.


When this function determines the certain level of the deviation between the feedback signal and the reference signal, it will stop the internal PID adjustment and maintain stable output. Only when

the deviation between the feedback value and the reference value of the close loop exceeds the deviation limit of P8.07 will the output be updated. Setting the deviation limit needs to take the

system control precision and stability into consideration.


This function determines the specific running mode during the process close loop adjustment.

If the output value of the close loop adjustment reaches frequency upper limit or lower limit (P0.13 or P0.14), there are two actions for selection in the integration section.
0: Stop integration adjustment: the integration value remains unchanged. When there is change occurring to the deviation between the reference value and the feedback value, the integration value

will follow that change trend.
1: Continue integration adjustment: The integration value will give immediate response to the change between the reference value and the feedback value unless this value reaches the internal

integration limit.  When there is change occurring to the deviation between the reference value and the feedback value changes, it needs to take longer time to offset the impact brought by the

continuous integration so that the integration value can catch up that change trend.
If the output value of the close loop adjustment is inconsistent with the current setup running direction, the close loop output value has two actions for selection.
0: It must be consistent with the setup running direction: When the output value of the close loop adjustment is inconsistent with the current setup running direction, the current output value will be

forced to be 0 internally.
1: It can be against the setup running direction: When the output value of the close loop adjustment is inconsistent with the current setup running direction, the close loop adjustment opposite to the

current setup running direction will be executed.

It determines the key motor parameters affecting the running control of the inverter through implementing the parameter auto-tuning. These motor parameters will be stored in the inverter

automatically upon completion of parameter auto-tuning process till next parameter input or another parameter auto-tuning.
The process of parameter auto-tuning is described as follows:
Input P9.00 to P9.04 properly in accordance with the motor nameplate; set the basic running frequency P0.15, maximum output frequency P0.11 and maximum output voltage P0.12; set the

acceleration/deceleration time P0.08 and P0.09 properly.

process.
　　2: Rotating parameter auto-tuning. Press the run key to measure the motor parameters P9.06 ~ P9.14 automatically and P9.15 will be restored to 0 automatically upon completion of auto-tuning

process.
　　Note:
If the motor can be disconnected from the load, it can select rotation auto-tuning (P9.15=2), or it can select static auto-tuning only. Make sure that the motor is in the static status when starting the

parameter auto-tuning. If there is over current or over voltage failure during the auto-tuning process, it can prolong the acceleration/deceleration time P0.08 and P0.09 properly.
If the inverter power does not match the motor power, select static auto-tuning. After the tuning, manually change the no load current P9.05 to about 40% of the motor rated current P9.04.
If the motor parameters are given, please enter the parameters to P9.05 ~ P9.09 directly. If the motor parameters are not given, please execute the parameter auto-tuning. The magnetic saturation and

coefficient value in P9.10 ~ P.14 is automatically set during auto-tuning, eliminating the need of setting by the user.

The unit’s place of P9.16 determines whether the motor overload protection is to be executed and whether the motor overload protection employs current mode or sensor mode.
0: Motor current mode: Overload is calculated in accordance with motor current, running frequency and running time and compared with the allowable motor overload time determined by P9.18.

Once the accumulated overload time is reached, the inverter will report “E.oL2” motor overload failure.
When the load type is constant torque (P9.00=0), the motor overload protection time P9.18 corresponds to the overload protection time under 150% rated load current and is 10 minutes by factory

default; when the load type is variable torque (P9.00=1), the motor overload protection time P9.18 corresponds to the overload protection time under 115% of rated load current and is 10 minutes by

factory default.
Note: The calculation of motor overload protection continues during the inverter running and stopping process, while the accumulated overload value will be reset when the inverter is power-off.

1: Sensor mode. Compare the analog feedback value of the thermal sensor installed on the motor with the present sensor protection threshold P9.17. If the feedback value is higher than that

protection threshold, the inverter will report “E.Ptc” motor overheat failure immediately, without inverse time lag characteristics.
Note: When this protection mode is employed, it needs to select the input channel for the analog feedback value of the thermal sensor and confirm that the input function of this analog channel is

selected as “5: Motor Temperature Feedback”.

6.11 Control Parameter (Group PA)

Carrier frequency has an important impact on operations of inverter and motor. When carrier frequency increases, the loss, temperature rise and noise of motor will decrease. If carrier frequency

decreases, the temperature rise of inverter itself as well as the leakage current of motor and its interference with external radiation will decrease.
PA.01 can be able to determine automatically the most suitable carrier frequency according to the temperature of inverter.
0: Non-auto adjustment, carrier frequency will not be adjusted automatically according to the temperature of inverter. Under favorable circumstances as regards ventilation and heat sink, all loads

shall operate with low noise. Set PA.00 with higher carrier frequency and set PA.01 to 0.
1: Auto-adjustment; inverter can adjust automatically carrier frequency through temperature check according to the weight of load. Maintain continuously reliable operation by keeping operating

with low noise at low loads and controlling the temperature of inverter at heavy load.


The function will be enabled when operating under vector control 1 (when P0.03=0~3).The function will help the inverter to keep the motor rotational speed constant if loads vary or under heavy

loads.

Fig. 6-32 Vector control 1 slip compensation gain

　　
When several inverters drive the same load, the function can distribute the load automatically between inverters and make them work cooperatively. For example, when some inverters run an

assembly line, this function can be used to balance loads, allocate loads between inverters at different power levels in proportion to the power, and thus ensure the assembly line operate properly.

Each inverter adjusts output frequency automatically according to its load condition and lifting ratio set by drooping control.
Note: This function is only applied to vector control 1.
　　
PA.04 current limit motion selection:
0: Invalid. Invalid for both processes of constant speed and acceleration/deceleration.
1: Valid. Valid for both processes of constant speed and acceleration/deceleration.
Generally, when setting speed or motor load varies sharply, output current of inverter may reach beyond over current protection value point, resulting over current error. Current limit function reduces

effectively occurrences of over current errors as inverter controls instantaneous output current and keep the sharply changed output current below protective motion value, thus ensuring continuous

and reliable operation of system. When current exceeds a certain value (PA.05), the inverter will turn into current limit status. When operating under constant speed, maintain stable load capacity

without producing over current error by current limit. When loads mitigate, exit the current limit status automatically, and return to work properly. The function is especially applied to applications of

suddenly changed speed or load.
　　Note:
Current limit current PA.05 is proportion of rated current of inverter. When torque load varies: 20.0~150.0%.
This function is only applied to vector control 1.
Under the current limit status, the speed of motor will decrease. The current limit function is not appropriate for systems that will not permit reduce speed, for example lifter, otherwise will loss of

control.


Unit place: Over-voltage adjustment: When motor with large inertial load stops rapidly, or a short-time regenerative braking happens for load abrupt changes when the motor operates, DC bus

voltage of inverter will rise, thus may result over-voltage protective motion. The function of voltage adjustment is in this case, decrease the braking torque to control the DC bus voltage to prenvent

over voltage alarm through adjust output frequency and auto prolong deceleration time.
Note: If energy-consumption braking is applied and braking unit (PA.09=1) has been set and applied, the function becomes invalid.
Tens place: Under-voltage adjustment: When power supply voltage decreases or instantaneous power-off; DC bus voltage will also decrease.The function of under-voltage adjustment is decrease the

motor rotating speed through decrease the output frequency, the load inertial energy feedback to DC side to keep DC voltage higher than the under valtage value,avoid stop by under voltage.Under

voltage function is very effective in applications such as centrifugal pump and fan.
Note: This function is only applied to vector control 1.
Hundreds place: Overmodulation: This function is used to increase output voltage of inverter and ensure the output capacity of the inverter under low grid voltage or under heavy load.

By setting PA07, ensure that output voltage will decrease automatically as the loads decrease under proper operation. The inverter maximally decreases reactive power to offer further energy savings.

Adjust the parameter according to real load conditions. The larger the parameter is, more visible the energy saving effect achieves, and the longer the response time lasts for the inverter converting

from energy saving condition to proper operation status.
　　Note:
This function is only applied to Vector control 1.
The function applies to valiable torque loads such as fan and pump. If used in applications of constant torque loads and rapidly changing loads, the function will result delayed control response.
This function is disabled during acceleration/deceleration process.
　　
　　
0: Magnetic flux braking disable
1: Magnetic flux braking enable
When the motor decreases, the inverter can rapidly slow down if magnetic flux braking action is selected. Then the electric energy can be transformed to heat energy during the braking process.
Rapid deceleration can be realized by selecting magnetic flux braking action, but the output current will be larger. Selecting no action, the deceleration will last longer, but the output current will be

smaller.


Determine whether to use energy consumption braking using braking unit selection PA.09.

For large rotating inertia applications and when rapid stop by braking is required, select matched braking unit and braking resistance and set braking parameter for the motor stop rapidly by braking.

　　
　　
Braking unit operating time PA.10 and braking unit action voltage PA.11 are only applied to inverter with built-in braking unit.
Braking unit action cycle is fixed to be 100s. If PA.09 is set as 1, the use rate of the braking unit is fixed to 100%. That is, the use time of the braking unit is fixed to 100.0s
Action voltage of braking unit can be selected by adjusting PA.11. The motor can be stopped rapidly by energy braking with the appropriate action voltage.
Note: Set PA.09 to 1 when using braking unit. For model selection of braking unit parts and connection, refer to 1.9 braking unit model selection.

The function can be used to auto reset from ordinary failures. The inverter will start to run automatically again after auto reset interval period PA.22. If the failure still exists as the inverter starts again

after auto reset times PA.21, it will alarm then stop. For defaults such as overcurrent or overvoltage occurred occasionally from beginning or during running, the function can be used if you want the

4: 4800bps
5: 9600bps
6: 19200bps
7: 38400bps
8: 57600bps
PC.01 sets communication format, odd-even check.
0: 1-8-1 format, without check.
1: 1-8-1 format, even check.
2: 1-8-1 format, odd check.
PC.02 sets the local address. 0 is the broadcast address, available address “1~247”, 248~255 for reservation.

PC.04 master-slave mode:
0: SCIA is slave mode and SCIB is slave mode;
1: SCIA is master mode and SCIB is slave mode;
2: SCIA is slave mode and SCIB is master mode.
PC.05 master to slave operation address (set by master), position for writing slave function code to master setting frequency:
0: P0.05  1: P8.00  2: P8.01
The inverter provides two communication ports. SCIA is a port connecting with operation panel, and SCIB is used terminal for 485+ and 485-.
In common applications, the inverter operates under slave mode (PC.04=0) and responses to external instructions.
Master mode: To active sent data to outside, which is often applied when multi-machines operate synchronously. When selecting master mode, one unit in a group of units often is set as a master to

transfer operating frequency instructions to other units. When the slave receives frequency instructions from the master, it will store these instructions at the position of function code specified by

PC.05. For example, if open loop digital frequency is given, adopt P0.05 as frequency reference and set PC.05=0.
If inverter master mode is set for SCIA/SCIB and operation panel has been inserted, the operation panel will take priority of controlling, and the function of inverter as master mode will lose effect

automatically. Pull out the operation panel, after 10 seconds the inverter will return back to master mode.

6.14 Vector Control 2 Parameters (Group Pd)
This group of functions is only valid for vector control 2. They are invalid for Vector control 1.


Note: The series of V5-H is only support speed model upon vector control, if torque control model
upon vector control is needed, please select the product series of V6-H.

Adjust proportional gain and integral time for the speed regulator.
Proportional gain P:
Adjust according to rotating inertia of machines connecting with motor. For machines with large rotating inertias, please increase P gain; for machines with small rotating inertias, please decrease P

gain.
When P gain is greater than inertia, although the control response can be accelerated, the motor may shock or overshoot. Reversely, if P gain is smaller than inertia, the control response will get

slower and the time taken to adjust the speed to the stable value will longer.
Integral time I:
The integral is invalid when setting the integral time I to 0 (controlled by P alone). To ensure the difference between the speed instructions and real speed is 0 under steady-state conditions, set the

integral time I to non-0 values. When I value is smaller, the system responses quickly. But if the value is very small, shock will occur. If I value is greater, the system responds slowly.
Adjust PI settings when operating quickly or slowly:
When the motor speed is greater than ASR switching frequency Pd.05, Pd.01 and Pd.02 will act to make the system obtain reasonable dynamic response when no shock occurs. If the motor speed is

smaller than ASR switching frequency Pd.05, Pd.03 and Pd.04 will act. To obtain reasonable dynamic response when operating slowly, increase proportional gain Pd.03 and reduce integral time Pd.04

properly.

Upon torque control, the speed cannot be controlled. When the set torque is larger than the load torque, the motor speed will keep rising to the speed limiting value. This function code sets the

forward/reverse maximum speed limiting value.
Note:
The analog channel input may be used to realize the maximum speed limiting upon torque control. Refer to the description of analog channel function selection P6.21.
When analog channel input is used to realize speed limiting, terminals can be used to forcefully use Pd.06 and Pd.07 as the speed limiting value.

　　

Pd.08 and Pd.09 are used to limit the maximum output torque of the inverter. The limit value is proportion of the rated output torque of motor. When large braking torque is required, please adopt

additionally the energy braking method.

Note: When setting P9.00 to 1, i.e. operating with variable torque load, the setting range of Pd.08 and Pd.09 change to 0.0~150.0%. The leave-factory value is 135.0%
　　

Pre-magnetizing is to create magnetize flux before the motor starts, aiming at fast response upon starting up of the motor. When operation instructions are available, bring the inverter into the pre-

magnetizing status in the time set by this function code. After establishing the magnetize flux, try to accelerate normally. If the function code is set to 0, no pre-magnetizing process is applied.
Note: The motor may rotate during pre-magnetizing, and then adopt mechanical braking additionally.

Fig. 6-37 Pre-magnetizing

Vector control will control the output current of motor and keep track of current instruction value. Scale and integral gain of current control (ACR) shall be set here. Usually the factory default shall

not be changed. Generally, increase P gain when coil inductance is high, decrease P gain when coil inductance is low. Current oscillation will be occurred as a result of setting I gain to extremely high.
　
When loads increase, motor slip will increase, but the rotating speed will decrease. The speed of motor can be controlled constantly by slip compensation. Please make adjustments according to

below conditions:
When the motor speed is below the setting target value, increase vector control slip compensation gain.
When the motor speed is above the setting target value, decrease vector control slip compensation gain.
Note: When the temperature of motor increases, interior parameters of motor will change and the slip will increase. Adjusting the function code can help to compensate the effects from temperature

rise of motor.

　　
When loads increase, motor’s slip will increase, and the rotating speed will also increase. The speed of motor can be controlled constantly by slip compensation. Please make adjustments according

to below conditions:
When the motor speed is below the setting target value, decrease vector control slip compensation gain.
　When the motor speed is above the setting target value, increase vector control slip compensation gain.
Note: When the temperature of motor increases, interior parameters of motor will change and the slip will increase. Adjusting the function code can help to compensate the effects from temperature

rise of motor.

　　
　This function defines the input filtering time of speed adjuster (ASR). In general, it needs no modification.

This function defines the input filtering time of speed adjuster (ASR). In general, it needs no modification.

XIII. How to change the direction that the inverter drives the motor to rotate-
A: (1) In the case of operation panel control, the direction is determined by P0.07. However, the FWD/REV key on the operation panel can real time change the direction.
A: (2) In the case of operation panel control, the direction is determined by P0.07. However, the UP/DN key on the operation panel (or the FWD/REV knob of the shuttle operation panel) can real time

change the direction.
A: (3) In the case of operation panel control, the positive/negative frequency value resulting from the final frequency calculation for composite control can also change the direction in real time.
A: (4) In the case of terminal control, check if the forward/reverse terminal is in one to one correspondence with that of the control equipment (e.g. PLC).

XIV. Why did the fans of inverters of certain power classes will rotate upon power up, while others could not-
A: The fans of the 15KW inverters and inverters of lower power class are under no control, and they will run when powered up. The operation of the fans of 18.5KW inverters and inverters of higher

power class is controlled by the heatsink temperature. When the inverter is powered up under low temperature condition, the fans will not run.

XV. What will happen if the CN1 busbar of the control board is loose or damaged-
A: If the CN1 busbar of the control board is loose or damaged, the inverter cannot run or will report several errors. For instance, the inverter may display “-LU- ” or “relay/contactor could not pull on

“, or report such errors as E.oc1, E.FAL, E.oH1, E.oH2, E.Cur and E.dL3 ect
