Brake choppers and brake resistors
An external brake resistor is needed to decelerate larger mo-
ments of inertia or in the event of longer operations in gener-
ator mode. It converts braking energy into heat.
ƒ
Brake modules and/or brake choppers are available for all
smd with three-phase mains supply.
