2 Parameters
2.2 List of parameters
p1215 Motor holding brake configuration / Brake config
Access level: 2
Can be changed: T
Unit group: -
Min
0
Description: Sets the holding brake configuration.
Value: 0:
1:
2:
3:
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
interconnected as control signal.
The parameter can only be set to zero when the pulses are inhibited.
p1216 Motor holding brake opening time / Brake t_open
Access level: 2
Can be changed: U, T
Unit group: -
Min
0 [ms]
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.
Recommendation: This time should be set longer than the actual opening time of the brake. This ensures that the drive cannot
accelerate when the brake is applied.
Dependency: Refer to: p1215, p1217
Note: For a motor with DRIVE-CLiQ and integrated brake, for p0300 = 10000, this time is pre-assigned the value saved in
the motor.
p1217 Motor holding brake closing time / Brake t_close
Access level: 2
Can be changed: U, T
Unit group: -
Min
0 [ms]
Description: Sets the time to apply the motor holding brake.
After OFF1 or OFF3 and the controlling (closing) of the holding brake, the drive remains stationary under closed-loop
control for this time with a speed setpoint of zero. The pulses are suppressed when the time expires.
Recommendation: This time should be set longer than the actual closing time of the brake. This ensures that the pulses are only
suppressed after the brake has closed.
Dependency: Refer to: p1215, p1216
Notice: If the selected closing time is too short with respect to the actual closing time of the brake, then the load can sag.
If the closing time is selected to be too long with respect to the actual closing time of the brake, the control works
against the brake and therefore reduces its lifetime.
Note: For a motor with DRIVE-CLiQ and integrated brake, for p0300 = 10000, this time is pre-assigned the value saved in
the motor.
