· The problem is that as the motor reduces its speed it increases the voltage on the DC bus of the drive. The only ways to handle this are: to length the time that the motor is slowing down (increase the deceleration time) or to bleed off the increased voltage by using braking resistors, or in fancy drives by adding a re-gen package and putting the voltage back into the AC supply, or even in ...
