Note:
If the configuration is set to "no holding brake present" at run-up, 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 sequential con-
trol".
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.
When the function module "extended brake control" is activated (r0108.14 = 1), r1229.1 should be interconnected
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 controlling the holding brake (opens), the speed/velocity setpoint remains at zero for this time. After this, the
speed/velocity setpoint is enabled.
Recommenda-
tion:
This time should be set longer than the actual opening time of the brake. This ensures that the drive cannot accel-
erate when the brake is applied.
Dependency:
Refer to: p1215, p1217
Description:
Sets the time to apply the motor holding brake.
After OFF1 or OFF3 and the holding brake is controlled (the brake closes), then the drive remains closed-loop con-
trolled for this time stationary with a speed setpoint/velocity setpoint of zero. The pulses are cancelled when the
time expires.
Recommenda-
tion:
This time should be set longer than the actual closing time of the brake. This ensures that the pulses are only can-
celed after the brake has closed.
Dependency:
Refer to: p1215, p1216, p1226, p1227
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.
Description:
Sets the signal source for a conditional opening of the motor holding brake.
