Simple PLC

16 steps speed can be set by in built PLC or terminals.

Inner PID

can realize close loop process control system

Automatic voltage regulation

can output constant voltage even grid voltage fluctuates.

Over voltage and over current control

automatic limitation to running voltage and current to

avoid frequent tripping

Fast limitation of current

To minimize over current faulty to make running smoothly.

Torque limitation

Excavator characteristics, torque limitation toavoid frequent

tripping. Torque control can be realized in Vector control mode.
