Onboard multiple preset speedsIt 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 cardSupport 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 .
