SINAMICS G120 / Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
Description: Sets the holding brake configuration.
Value: 0: No motor holding brake being used
3: Motor holding brake like sequence control, connection via BICO
Dependency: Refer to: p1216, p1217, p1226, p1227, p1228
Caution: For the setting p1215 = 0, if a brake is used, it remains closed. If the motor moves, this will destroy the brake.
Notice: If p1215 was set to 3, then when the pulses are suppressed, the brake is closed even if the motor is still rotating.
Pulse suppression can either be caused by a 0 signal at p0844, p0845 or p0852 or as a result of a fault with OFF2
response. If this is not desirable (e.g. for a flying restart), then the brake can be kept open using a 1 signal at p0855.
Note: if an external motor holding brake is being used, then p1215 should be set to 3 and r0899.12 should be intercon-
nected as control signal.
The parameter can only be set to zero when the pulses are inhibited.
Description: Sets the holding brake configuration.
Value: 0: No motor holding brake being used
1: Motor holding brake acc. to sequence control
2: Motor holding brake always open
3: Motor holding brake like sequence control, connection via BICO
Dependency: Refer to: p1216, p1217, p1226, p1227, p1228
Caution: For the setting p1215 = 0, if a brake is used, it remains closed. If the motor moves, this will destroy the brake.
Notice: If p1215 was set to 1 or if p1215 was set to 3, then when the pulses are suppressed, the brake is closed even if the
motor is still rotating. Pulse suppression can either be caused by a 0 signal at p0844, p0845 or p0852 or as a result
of a fault with OFF2 response. If this is not desirable (e.g. for a flying restart), then the brake can be kept open using
a 1 signal at p0855.
Note: If a holding brake integrated in the motor is used, then it is not permissible that p1215 is set to 3.
if an external motor holding brake is being used, then p1215 should be set to 3 and r0899.12 should be intercon-
nected as control signal.
The parameter can only be set to zero when the pulses are inhibited.
Description: Sets the time to open the motor holding brake.
After the holding brake has been controlled (opened), the speed setpoint remains at zero for this time. After this, the
speed setpoint is enabled.
Dependency: Refer to: p1215, p1217
