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
