When braking is necessary, the system decreases the frequency and increases the flux in the
motor. This increases the capacity of the motor to brake. The motor speed is controlled
during braking.
You can enable and disable Flux Braking.
CAUTION!
Use the braking only intermittently. Flux braking converts energy into heat and can
cause damage to the motor.
