p1130 Ramp-function generator
initial rounding-off time
0.000 30.000 0.000 s Float IM T, U
Description:
Sets the initial rounding-off time for the extended ramp generator. The value applies to ramp-up
and ramp-down.
Note: Rounding-off times avoid an abrupt response and prevent damage to the mechanical system.
p1131 Ramp-function generator
final rounding-off time
0.000 30.000 0.000 s Float IM T, U
Description:
Sets the final rounding-off time for the extended ramp generator. The value applies to ramp-up
and ramp-down.
Note: Rounding-off times avoid an abrupt response and prevent damage to the mechanical system.
p1135
OFF3 ramp-down time
0
600
0
s
Float
IM
T, U
Description: Sets the ramp-down time from the maximum speed down to zero speed for the OFF3 command.
Note: This time can be exceeded if the DC link voltage reaches its maximum value.
p1215 * Motor holding brake con-
figuration
0 2 0 - I16 IM T
Description: Sets the holding brake configuration.
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, then when the pulses are suppressed, the brake is closed even if the motor is
still rotating.
Note: The parameter can only be set to zero when the pulses are inhibited.
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.
Dependency: Refer to p1215, p1217
Note:
For a motor with integrated brake, this time is pre-assigned the value saved in the motor.
For p1216 = 0 ms, the monitoring and the message A7931 "Brake does not open" are deactivated.
p1217 * Motor holding brake clos-
ing 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 suppressed
when the time expires.
Dependency: Refer to p1215, p1216
Note:
For a motor with integrated brake, this time is pre-assigned the value saved in the motor.
For p1217 = 0 ms, the monitoring and the message A07932 "Brake does not close" are deactivated.
p1226 Threshold for zero speed
detection
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.
