n Excellent Control Performance under Speed Sensorless Vector Control Mode
u Realizing AC motor decoupling, enabling the DC motorization of operation control.
u Fig. 1 indicates the four-quadrant operation of the motor under speed sensorless vector control. The torque, current, speed and DC bus voltage have quick response, and the motor has stable operation.
u Realizing 0.1s acceleration/deceleration with rated motor load.
u Upon the zero-crossing switching of the motor (forward/reverse switching), the current has no phase mutation or oscillation, and the rotating speed has no pulsation.
u The bus voltage is under stable control. Quick and reliable braking can be realized when decelerating under the condition of braking without power consumption.
It is especially suitable for:
The reciprocating equipment, such as numerical control machine, fountain control machine, weaving machine and jacquard.
n Realizing Real Tripless Operation
u With excellent current and voltage control technology, 0.1s repetitive and alternate acceleration and deceleration is performed, and the inverter realizes stable and tripless operation.
u With extremely powerful loading capacity, the inverter can realize stable tripless operation in any acceleration/deceleration time and under any impact load condition.
u With strong short-time overload capacity, the inverter can operate continuously for 0.5s under 200% rated load, and 1 minute under 150% rated load.
u The intelligent module temperature control maximizes the loading capacity of the inverter.
It is especially suitable for:
The heavy-duty equipment, such as injection molding machine (modification for energy saving), lifting equipment, numerical control machine, rolling mill, furnace feeding equipment.
n Large Torque and Stable Operation at Low Frequency under Vector Control
u With precise speed identification and rotor magnetic flux orientation, the torque responds quickly and stable operation in the case of 0.25Hz load mutation.
u Startup torque: Open loop vector control: 0.25Hz; 180% rated torque
u Speed stabilization precision: Open loop vector control: ±0.2%
It is especially suitable for:
Medium and large wire-drawing machine, pipe and cable processing, lifting equipment, rolling mill.
n Unique Quick DC Braking
u Within the range of 0 to 300Hz, the inverter can realize back electromotive force elimination and quick DC braking within 0.3s.
u DC current input in the most efficient way to improve the braking capacity.
u There is no initial waiting time for the DC braking.
u Special function code of the initial waiting time for DC braking setting is cancelled.
It is especially suitable for:
Lifting equipment, invertible roll table for rolling mill, weaving machine, paper making production line.
n Unique Instantaneous Mains Failure Reaction
u Upon the instantaneous mains failure, the energy of the motor feedback bus will keep the inverter running till the mains resumes normal.
u When shutdown is caused by long-term power-failure during the operation of the inverter, the inverter will provide alarm message after power resumes normal.
u It supports the automatic operation after power-up.
u The deceleration time during the power failure and the acceleration time after the power recovery can be set independently.
It is especially suitable for:
Instantaneous power-failure startup equipment, such as chemical fiber and weaving equipment, multi-point synchronization linkage equipment, fan/pump, etc.
n Unique Speed Tracing Function
u It doesn’t need special hardware detection circuit and no special function code to be set. Within the range of 0 to 60Hz, the inverter can complete identification the motor rotating speed, rotating direction and phase angle within 0.2s, and start smooth tracing on the freely rotating motor.
u Tracing mode 1: Quick and smooth tracing on the free speed motor without any impact.
It is especially suitable for:
The equipment whose operation shall be traced upon the power recovery after instantaneous power failure, such as fan and pump.
u Tracing mode 2: Impactlessly pull down the motor from high-speed to low speed and then accelerate to normal speed.
n Unique Quick DC Braking
u Within the range of 0 to 300Hz, the inverter can realize back electromotive force elimination and quick DC braking within 0.3s.
u DC current input in the most efficient way to improve the braking capacity.
u There is no initial waiting time for the DC braking.
u Special function code of the initial waiting time for DC braking setting is cancelled.
It is especially suitable for:
Lifting equipment, invertible roll table for rolling mill, weaving machine, paper making production line.
