DC-braking / Mode
DC-braking / Time
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.

Note:
If the braking time depends on the actual frequency (CP.22 = 2...7), it is
calculated as follows:
