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.
p1135 OFF3 ramp-down time
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
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.
