n Multiple Frequency Reference Modes, Flexible and Convenient for Operation
u Operation panel reference (digital reference). The operation panel can be used to conduct ∨/∧ adjustment on the frequency reference.
u Terminal reference:
1) Analog AI1/AI2: 0 to 10V or 0 to 20mA
2) Analog AI3: -10V to 10V
3) Pulse frequency X7/DI: 0.2Hz to 50kHz
4) Xi terminal: UP/DN mode independent, able to superpose with any other frequency reference mode
u Communication mode reference: International standard Modbus protocol.
u The above reference modes can be switched online.
n Multiple Channels for Reference and Feedback
u Under the open loop mode and analog feedback close loop mode, the reference value can define the main and auxiliary calculation relation:
5) Main reference + auxiliary reference
6) Main reference - auxiliary reference
7) Main reference + auxiliary reference -50%
8) Max (main reference, auxiliary reference)
9) Min (main reference, auxiliary reference)
u The sign of the main and auxiliary reference calculation (positive or negative) can automatically determine the rotation direction of the motor.
u Under the analog feedback close loop mode, the feedback value can also define the main and auxiliary calculation relation before it enters the process PID for adjustment control.
It is especially suitable for:
The continuous and automatic production lines, such as paper making, printing and dyeing, packaging and printing.
The temperature difference and pressure difference applications, such as the chilled water control of the central air conditioner, the water supply system.
n Digital Operation Panel
u Button type and shuttle type selectable, RS485 communication mode, standard network port connection.
u The button layout complies with the human engineering principle. One-button function code access and exit, making it easy for the operation.
u The standard configuration operation panel can realize parameter copy and remote control function (maximum length: 500m).
u With unique multifunctional button M, the following functions can be defined:
10) JOG
11) Emergency shutdown 1 (fastest shutdown)
12) Emergency shutdown 2 (free shutdown)
13) Reference mode switch through operating command (operation panel reference →terminal reference→host computer reference →operation panel reference)
14) FASt/bASE menu switch
15) Menu mode switching (bASE→FASt→ndFt→LASt→bASE)
n Host Computer Communication
u The operation panel and terminals provide 485 ports, the communication protocol is Modbus, and host computer monitoring software is provided.
u Master slave communication control among several inverters can be realized.
u Parameter upload and download can be realized.
u Cascade transmission of operating frequencies for several inverters can be realized to provide digital frequency divider functions.
