Par. No. Name
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: p1082
p1121 Ramp-function generator ramp-
down time
Description: 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: p1082
p1215 Motor holding brake configura‐
tion
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
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 cannot
accelerate when the brake is applied.
Dependency: p1215, p1217
p1217 Motor holding brake closing
time
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.
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
