Simple PLC   It can realize at maximum of 16 segments speed
Basic function  Multiple segment speed running Running via the built-in PLC or control terminal.
Built-in PID It is easy to realize process-controlled closed loop control system.
Auto voltage regulation (AVR) It can keep constant output voltage automatically in the case of change of network voltage.
Over-voltage/current stall control It can limit the running voltage/current automatically and prevent frequent over-voltage/current tripping during the running process.
Quick current limit Minimize the over-current fault, protect normal operation of the AC Drive.
Torque limit & control “Excavators” characteristics, automatically limit torque during operation, prevent frequent over-current tripping. Closed loop vector mode can realize the torque control.
Personalized function Instantaneous stop non-stop When instantaneous power off, voltage reduction is compensated through load feedback energy, which could make AC Drive keep running in a short period of time.
Rapid current limit To avoid AC Drive frequent over-current fault.
Timing control Timing control function:set time range 0Min~6500.0Min.
Running Command source Operation panel reference, control terminal reference and serial communication port reference. These channels can be switched in various modes.
Frequency source There are totally eleven types of frequency sources, such as digital reference, analog voltage reference , analog current reference, pulse reference, MS speed, PLC, PID and serial port reference.
Input terminal 5 digital input terminals.
2 analog input terminals.
