Description: Sets the starting speed for DC braking.
If the actual speed falls below this threshold, then DC braking is activated.
Dependency: Refer to: p1230, p1231, p1232, p1233, r1239
Notice: If an encoder fault occurs during closed-loop operation with an encoder, controlled deceleration of the drive down to
the start speed p1234 is no longer possible. In this case, DC braking is activated immediately and injects the braking
current p1232 for the braking time p1233 after de-magnetizing. The braking current and braking duration must,
therefore, be dimensioned accordingly for this situation so that the drive can be decelerated to standstill.
In the case of operation with an encoder, this speed may not be set too low so as ensure that the oscillation
movement induced by the residual flux/remanence of the motor does not cause DC braking to be de-activated again.
Note: Function p1231 = 14 is activated at 15 1/min higher than the value set in p1234. This hysteresis is required to prevent
DC braking from being deactivated for speed encoder signals with ripple.
Description: Sets the signal source for the contactor feedback signal for external armature short-circuit.
Dependency: Refer to: p1230, p1231, p1236, p1237, r1239
Notice: In order that the pulses are not enabled when the contactor is closed, the contactor feedback signal must lag by a
sufficiently long time when opening the contactor.
Note: 1 signal: The contactor is closed.
0 signal: The contactor is open.
Description: Sets the monitoring time of the contactor feedback signal for the external armature short-circuit configuration.
If the contactor feedback signal (p1235) is parameterized, then the appropriate feedback signal (r1239.1) is expected
within this monitoring time after either opening or closing the contactor.
Dependency: Refer to: p1230, p1231, p1235, p1237, r1239
Description: Sets the delay time when opening the contactor of the external armature short-circuit.
