2 Parameters
2.2 List of parameters
Description:
Sets the holding brake configuration.
Value:
0:
No motor holding brake available
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, p1278
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 the configuration is set to "no holding brake present" when booting, then the motor holding brake will be
automatically identified. If a motor holding brake is detected, the configuration is set to "motor holding brake as for
sequence control".
If a motor holding brake is used via the brake connection of the Power Module integrated in the drive, 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.
The parameterization "no motor holding brake available" and "Safe Brake Control" enabled (p1215 = 0, p9602 = 1,
p9802 = 1) is not practical if there is no motor holding brake.
The parameterization "motor holding brake the same as sequence control, connection via BICO" and "Safe Brake
Control" enabled (p1215 = 3, p9602 = 1, p9802 = 1) is not practical.
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. The speed
setpoint is then 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.
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.
