fluctuating

Control

Function

Common DC bus

Common DC bus for several inverters, energy balanced automatically

Torque control

Torque control without PG

Torque limit

“Rooter” characteristics, limit the torque automatically and prevent

frequent over-current tripping during the running process

Wobble frequency control

Multiple triangular-wave frequency control, special for textile

Timing/length/counting control

Timing/length/counting control function

Over-voltage & over-current stall control

Limit current & voltage automatically during the running process,

prevent frequent over-current & over-voltage tripping

Fault protection function

Up to 30 fault protections including over-current, over-voltage,

under-voltage, overheating, default phase, overload, shortcut, etc., can

record the detailed running status during failure & has fault automatic

reset function
