onboard multiple preset speeds

It implement s up to 16speeds via the simple

PLC function or combination of x 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.

over voltage l

over current s tall control

The current and voltage are limited automatically during the running process so as to avoid

frequent tripping due to over voltage l  over current.

Torque limit and control

It can limit the torque automatically and prevent  frequent over current tripping during the

running process.

Torque control can be implemented in the CLVC mode.

support for multiple PG card

Support for rotating transformer PG card, differential input PG card, UVW differential input

PG card, resolve r PG cardan doc input PG card

power dip ride through

The load feedback energy compensate s the voltage 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.
