Simple PLC and MS speed runningIt can realize at maximum of 16 segments speed running via the built-in PLC or control terminal.
Built-in PIDIt 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 controlIt can limit the running voltage/current automatically and prevent frequent over-voltage/current tripping during the running process
Quick current limitMinimize 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.
