DC-braking / Mode
If the braking time depends on the actual frequency (CP.22 = 2...7), it is calculated as
follows:
CP.23 x f
real
t
Breal
= –––––––––
100 Hz
Otherwise the braking time corresponds to CP.23.
Adjustment range: 0,00...100,00 s
Resolution: 0,01 s
Factory setting: 10,00 s

CP.23
With DC-braking the motor is not decelerated by the ramp. Quick braking is caused by
D.C. voltage, which is applied onto the motor winding. This parameter determines how
the dc-braking is triggered.
Value Activation
0 DC-braking deactivated
1 DC-braking at switch off of the direction of rotation and upon reaching
0Hz. The braking time is CP.23 or until the next direction of rotation.
2* DC-braking as soon as setting for the direction of rotation is absent.
3* DC-braking as soon as the direction of rotation changes or is absent.
4* DC-braking on disabling the direction of rotation and if the real
frequency falls below 4 Hz.
5* DC-braking when the real frequency falls below 4 Hz.
6* DC-braking as soon as the set value falls below 4 Hz.
7* DC-braking when input I4 is switched. Braking time depends on the real
frequency. At control circuit B = value "0"
8 DC-braking as long as input I4 is switched. At control circuit B = value
"0"
9 DC-braking after switching on the modulation on.
* Braking time depends on the actual frequency.
Adjustment range: 0...9
