Power loss ride-through

If the incoming supply voltage is cut off, the drive continues to operate by utilizing the
kinetic energy of the rotating motor. The drive is fully operational as long as the motor
rotates and generates energy to the drive. The drive can continue the operation after
the break if the main contactor remained closed.

to the minimum limit. The controller keeps the voltage steady as long as the input power is
switched off. The drive runs the motor in generator mode. The motor speed falls but the drive is
operational as long as the motor has enough kinetic energy.
