|
|
Simple PLC, multistage speed operation
|
It implements up to 16 speeds via the simple PLC function or combination of DI terminal states.
|
|
Built-in PID
|
It can keep constant output voltage automatically when the mains voltage changes.
|
|
Automatic voltage regulation（AVR）
|
Automatically maintain a constant output voltage when grid voltage changes.
|
|
Over voltage/Over current loss of speed control
|
Automatic limit of the current and voltage during the operation, prevent frequent over current and over voltage
|
|
Rapid current limit
|
Minimizing over-current fault and protect the normal operation of converter.
|
|
Torque limit and control
|
"Excavator" characteristics, automatic limit of the torque during the operation, to prevent frequent over-current trip. Closed-loop vector mode torque control can be achieved.
