Parameters
10.2 Parameter list
Par. No. Name
p1086 * Speed limit in negative
direction of rotation
Description: Sets the speed limit for the negative direction.
Note: The parameter values displayed on the BOP are integers.
p1115 Ramp-function generator
selection
Description: Sets the ramp-function generator type.
Note: Another ramp-function generator type can only be selected when the motor is at a standstill.
p1120 Ramp-function generator
ramp-up time
Description: The ramp-function generator ramps-up the speed setpoint from standstill (setpoint = 0) up to the
maximum speed (p1082) in this time.
Dependency: Refer to p1082
p1121 Ramp-function generator
ramp-down time
Description: Sets the ramp-down time for the ramp-function generator.
The ramp-function generator ramps-down the speed setpoint from the maximum speed (p1082) down to
standstill (setpoint = 0) in this time.
Further, the ramp-down time is always effective for OFF1.
Dependency: Refer to p1082
p1130 Ramp-function generator
initial rounding-off time
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
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.
p1215 * Motor holding brake con-
figuration
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 or if p1215 was set to 3, then when the pulses are suppressed, the brake is
closed even if the motor is still rotating.
Note: If a holding brake integrated in the motor is used, then it is not permissible that p1215 is set to 3.
The parameter can only be set to zero when the pulses are inhibited.
