7.7.1.1 Flux braking
P2.7.1.7 Flux brake ID520
Instead of DC braking, flux braking is a useful way to raise the braking capacity in cases
where additional brake resistors are not needed.
When braking is needed, the frequency is reduced and the flux in the motor is increased.
This increases losses on motor, which in turn increases the motor's capability to brake.
Unlike in DC braking, the motor speed remains controlled during braking.
The flux braking can be set ON or OFF.
0 = Flux braking OFF

Defines the flux braking current value. The value setting range depends on the used unit
size.
