de-magnetization of the motor can be observed. This time is proportional to the speed at the moment of the
injection of direct current.

During the braking process, if the inverter is enabled, the braking is interrupted and the inverter will start
operating normally.
ATTENTION!
The DC braking can continue acting even if the motor has already stopped. Be careful with the thermal
dimensioning of the motor for short-period cyclic braking.
