The energy generated during braking is
refed to the DC-BUS. The Elkos
DC-Buses are able to store only a small
amount of energy. The excess energy
has to be converted into heat in the
regenerative resistor. The internal
resistor is designed for drives without
flyweights.
Always use external regenerative
resistors for flyweights or design
uncertainties.
