519 Flux braking current
(2.4.13)
Defines the flux braking current value. This value can be set between 0.4*I
H
and the
Current limit.
520 Flux brake
(2.4.12)
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,
which in turn increases the motor's capability to brake. Unlike DC braking, the motor
speed remains controlled during braking.
The flux braking can be set ON or OFF.
0 = Flux braking OFF
1 = Flux braking ON
Note: Flux braking converts the energy into heat at the motor, and should be used
intermittently to avoid motor damage.
521 Motor control mode 2
(2.5.12)
With this parameter you can set another motor control mode. Which mode is used is
determined with parameter ID164.
For the selections, see parameter ID600.
