Onboard
multiple
preset speeds
It implements up to 16 speeds 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.
Overvoltage/
Overcurrent
stall
control
The current and voltage are limited automatically during the running process so as to
avoid frequent tripping due to overvoltage/overcurrent.
Torque limit and
control
It can limit the torque automatically and prevent frequent
over current tripping during the running process.
