What is Dynamic Breaking?
Dynamic braking is a way to increase the braking capability of a variable speed drive by dissipating the excess energy into a high power resistor connected across the internal DC link. When a VSD is given a stop signal, the VSD output decelerates to zero but the motor can carry on running due to load inertia and mechanical energy with the motor acting as a generator. This energy flows back from the motor into the DC link capacitors in the variable speed drive and causes the DC link voltage to rise. If the DC voltage exceeds 750Vdc the drive will trip to protect the capacitors and connected devices.
