Description:
Sets the holding brake configuration.
• 0: No motor holding brake being used
• 1: Motor holding brake according to sequence control
• 2: Motor holding brake always open
•
3: Motor holding brake like sequence control
Dependency: p1216, p1217, p1226, p1227, p1228
p1216 Motor holding
brake, opening
time
0 10000 100 ms Float IM T, U
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.
This time should be set longer than the actual opening time of the brake, which ensures that the drive can-
not accelerate when the brake is applied.
Dependency: p1215, p1217
p1217 Motor holding
brake closing
time
0 10000 100 ms Float IM T, U
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 controlled for this time stationary with a speed setpoint/velocity setpoint of zero. The pulses are sup-
pressed when the time expires.
This time should be set longer than the actual closing time of the brake, which ensures that the pulses are
only suppressed after the brake has closed.
Dependency: p1215, p1216
p1226 Threshold for
zero speed de-
tection
0.00 210000.00 20.00 rpm Float IM T, U
Description:
Sets the speed threshold for the standstill identification.
Acts on the actual value and setpoint monitoring.
• When braking with OFF1 or OFF3, when the threshold is undershot, standstill is identified.
The following applies when the brake control is activated:
• When the threshold is undershot, the brake control is started and the system waits for the brake closing
time in p1217. The pulses are then suppressed.
If the brake control is not activated, the following applies:
•
When the threshold is undershot, the pulses are suppressed and the drive coasts down.
Dependency: p1215, p1216, p1217, p1227
p1227 Zero speed
detection moni-
toring time
0.000 300.000 300.000 s Float IM T, U
Description:
Sets the monitoring time for the standstill identification.
When braking with OFF1 or OFF3, standstill is identified after this time has expired, after the setpoint speed
has fallen below p1226.
After this, the brake control is started, the system waits for the closing time in p1217 and then the pulses are
suppressed.
Dependency: p1215, p1216, p1217, p1226

sion delay time
