DC voltage control
Overvoltage control
Overvoltage control of the intermediate DC link is typically needed when the motor is
in generating mode. To prevent the DC voltage from exceeding the overvoltage
control limit, the overvoltage controller automatically decreases the generating torque
when the limit is reached.
Undervoltage control
If the incoming supply voltage is cut off, the drive will continue to operate by utilizing
the kinetic energy of the rotating motor. The drive will be fully operational as long as
the motor rotates and generates energy to the drive. The drive can continue
operation after the break if the main contactor (if present) remained closed.
