After this, the brake control is started, the system waits for the closing time in p1217 and then the pulses are can-
celed.
Dependency: Refer to: p1215, p1216, p1217, p1226
Notice: For p1145 > 0.0, 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 canceled.
Note: Standstill (zero speed) is detected if, during the complete monitoring time (p1227), the speed setpoint falls below
the speed threshold (p1226).
For p1227 = 300.000 s, the following applies:
The monitoring is deactivated.
For p1227 = 0.000 s, the following applies:
With OFF1 or OFF3 and a ramp-down time = 0, the pulses are immediately canceled and the motor "coasts" down.
Description: Sets the delay time for pulse cancelation.
After OFF1 or OFF3 and zero speed detection, the system waits for this time to expire and the pulses are then can-
celed.
Dependency: Refer to: p1226, p1227
Note: Standstill (zero speed) is detected if, during the complete delay time (p1228), the speed actual value falls below the
speed threshold (p1226).
Description: Displays the status word for the motor holding brake.
