Simple PLC and Multi-speed running

It can realize at maximum of 16 segments speed 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

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 frequently over-current fault.
