Notice: For p1145 > 0.0 (RFG tracking) the setpoint is not equal to zero dependent on the selected value. This can therefore
cause the monitoring time in p1227 to be exceeded. In this case, for a driven motor, the pulses are not suppressed.
Note: Standstill is identified in the following cases:
- the speed actual value falls below the speed threshold in p1226 and the time started after this in p1228 has expired.
- the speed setpoint falls below the speed threshold in p1226 and the time started after this in p1227 has expired.
For p1227 = 300.000 s the following applies:
Monitoring is de-activated.
For p1227 = 0.000 s, the following applies:
With OFF1 or OFF3 and a ramp-down time = 0, the pulses are immediately suppressed and the motor "coasts" down.
Once the Control Unit has been booted up for the first time or if the factory settings have been defined accordingly,
the parameter is defined in accordance with the power unit.
Description: Sets the delay time for pulse suppression.
After OFF1 or OFF3, the pulses are canceled, if at least one of the following conditions is fulfilled:
- the speed actual value falls below the threshold in p1226 and the time started after this in p1228 has expired.
- the speed setpoint falls below the threshold in p1226 and the time started after this in p1227 has expired.
Dependency: Refer to: p1226, p1227
Notice: When the motor holding brake is activated, pulse cancellation is additionally delayed by the brake closing time
(p1217).
Description: Sets the signal source to activate DC braking.
Dependency: Refer to: p1231, p1232, p1233, p1234, r1239
Note: 1 signal: DC braking activated.
0 signal: DC braking de-activated.
Description: Setting to activate DC braking.
Value: 0: No function
4: DC braking
5: DC braking for OFF1/OFF3
14: DC braking below starting speed
Dependency: Refer to: p0300, p1232, p1233, p1234, r1239
