10.3.3 Compound Braking
When Compound braking is used, most of the energy is dissipated in the motor
instead of coming back into the DC link. This has the advantage that the braking
performance of the inverter can be increased, without tripping the inverter and
without the use of a braking resistor.
Compound braking combines the braking power of DC braking with the control
offered by a ramp down. When using Compound braking, the ramp-down time is
defined and the level of current to be used in Compound Braking is defined using
P1236.
