The drive monitors the motor status continuously, also during the Flux Braking.
Therefore, Flux Braking can be used both for stopping the motor and for changing
the speed. The other benefits of Flux Braking are:
• The braking starts immediately after a stop command is given. The function does
not need to wait for the flux reduction before it can start the braking.
• The cooling of the motor is efficient. The stator current of the motor increases
during the Flux Braking, not the rotor current. The stator cools much more
efficiently than the rotor.
