The braking torque at capacitive feedback is the average deceleration torque at the shortest deceleration (stoppage from 50 Hz) of the motor itself. It is not the continuous regenerative braking torque. And the average deceleration torque varies with motor loss. This value decreases when operating beyond 50/60 Hz. If a large regeneration torque is required, the optional braking resistor should be used.
