3.3.2 Brake resistor (Optional)
During dynamic braking of the motor, electrical energy is returned to the servo controller. To prevent
over-voltage cut-off , the integrated brake chopper, can convert the recovered energy into heat by
connecting an external brake resistor (optional). The capacity of the brake resistor must be matched to
the relevant application. The customer can select from a wide range of capacities. Generally, the
following assignments apply to most application cases, sizes are calculated from the mass being
braked and the cycle times:
