RAKE
Instead of DC braking, flux braking is a useful form of braking with motors of
max. 15kW.
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.
Note:
Flux braking converts the energy into heat at the motor, and should be
used intermittently to avoid motor damage.
Activation mode
Description
0
= Off
Not used
1
= On
Normal mode. Activates flux bracking during deceleration
regardless of load.
2
= Chopper
Emulates the behavior of a braking chopper by activating
flux bracking based on DC-link voltage. Minimizes the heat-
ing up of the motor in applications with frequent speed
changes.
3
= Full mode
Activates flux bracking both during deceleration and on gen-
erative shock loads at constant speed. Offers the highest
performance in demanding applications.
