Onboard multiple preset speeds The system implements up to 16 speeds by using simple
PLC function or by using digital input signals.
Onboard PID The system implements the proportionalegral-derivative
(PID) function in the closed-loop control.
Automatic voltage regulation (AVR) The system maintains a constant output voltage
automatically when the grid voltage changes through the
permissible range.
Overvoltage and overcurrent stall
control The system limits the output current and voltage
automatically during operation to prevent frequent or
excessive trips.
Torque limit and control The system limits the torque automatically to prevent
frequent overcurrent tripping during operation.
Torque control is applied in vector control.
Individualized
functions Power dip ride-through Load feedback energy compensates for any voltage
reduction, allowing the drive to continue to operate for a
short time during power dips.
Overcurrent fast prevention The function helps to avoid frequent overcurrent faults.
