Simple PLC and Multi-speed running
It can realize at maximum of 16 segments speed running via the built-in PLC or control terminal.
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.
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 frequently over-current fault.
Timing control function：set time range 0Min~6500.0Min
Running command channel
Three types of channels： operation panel reference, control terminal reference and serial communication port reference. These channels can be switched in various modes.
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.
