Onboard multiple preset speeds

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

Onboard PID

It realizes process-controlled closed loop control system easily

Auto voltage Regulation (AVR)

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

Overvoltage /Overcurrent stall control

The current and voltage are limited automatically during the running process so as to avoid frequenct tripping due to overvoltage /over current

Torque limit and control

It can limit torque automatically and prevent frequent over current tripping during the running process .Torque control can be implemented in the CVC mode

Support for the multiple PG card

Support for rotating transformer PD card , differential input PG card, resolver PG card and OC input PG card

Power dip ride through

Reduction so that the AC drive can continue to run for a short time

Rapid current limit

It helps to avoid frequent over current faults of the AC drive

High performance

Control of asynchronous motor and synchronous motor are implemented through the high -performance current vector control technology .

Timing control

Time range : 0.0~ 6500.0  mintes

Communication Methods


Protection mode

Motor short -circuit detection at power -on , input/output phase loss protection ,over current protection, overvoltage protection, under voltage protection , overheat protection and overload protection
