  • Page 121 • parameter descriptions vacon LUX BRAKING Instead of DC braking, flux braking is a useful form of braking with motors of max. 15 kW. When braking is needed, the frequency is reduced and the flux in the motor is increased, which in turn increases the motor's capability to brake. Unlike DC braking, the motor speed remains controlled during braking.
