Simple PLC & multi-step speed operation It can realize a maximum of 16 segments speed running via the built-in PLC or control terminal.

Built-in PID Built-in PID control to easily realize the close loop control of the process parameters (such as pressure, temperature, flow, etc.)

Automatic voltage regulation Keep output voltage constant automatically when input voltage 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
