Jog control

Jog frequency: 0.00Hz~50.00Hz

Jog acceleration and deceleration tome:0.0s~6500.0s

Simple PLC, multistage speed operation

It implements up to 16 speeds via the simple PLC function or combination of DI terminal states.

Built-in PID

It can keep constant output voltage automatically when the mains voltage changes.

Automatic voltage regulation(AVR)

Automatically maintain a constant output voltage when grid voltage changes.

Over voltage/Over current loss of speed control

Automatic limit of the current and voltage during the operation, prevent frequent over current and over voltage

Rapid current limit

Minimizing over-current fault and protect the normal operation of converter.

Torque limit and control

"Excavator" characteristics, automatic limit of the torque during the operation, to prevent frequent over-current trip. Closed-loop vector mode torque control can be achieved.
