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.
The brake resistors recommended in the table are designed
for around 1.5 times the regenerative power for a cycle time
of 15/135 s (brake/pause). The brake resistors are fitted with
a thermostat (potential-free NC contact).
