Siemens SINAMICS G120 List Manual page 205

Note: p1134 = 0 (continuous smoothing)
If the setpoint is reduced while ramping-up, initially a final rounding-off is carried out and then the ramp-up
completed. During the final rounding-off, the output of the ramp-function generator continues to go in the direction of
the previous setpoint (overshoot). After the final rounding-off has been completed, the output goes toward the new
setpoint.
p1134 = 1 (discontinuous smoothing)
If the setpoint is reduced while ramping-up, then the output goes immediately in the direction of the new setpoint. For
the setpoint change there is no rounding-off.
p1135[0...n] OFF3 ramp-down time / OFF3 t_RD
Access level: 2
Can be changed: C(1), U, T
Unit group: -
Min
0.000 [s]
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.
p1136[0...n] OFF3 initial rounding-off time / RFGOFF3 t_strt_rnd
Access level: 3
Can be changed: U, T
Unit group: -
Min
0.000 [s]
Description: Sets the initial rounding-off time for OFF3 for the extended ramp generator.
p1137[0...n] OFF3 final rounding-off time / RFG OFF3 t_end_del
Access level: 3
Can be changed: U, T
Unit group: -
Min
0.000 [s]
Description: Sets the final rounding-off time for OFF3 for the extended ramp generator.
p1138[0...n] CI: Ramp-function generator ramp-up time scaling / RFG t_RU scal
Access level: 3
Can be changed: T
Unit group: -
Min
-
Description: Sets the signal source for scaling the ramp-up time of the ramp-function generator.
Dependency: Refer to: p1120
Note: The ramp-up time is set in p1120.
p1139[0...n] CI: Ramp-function generator ramp-down time scaling / RFG t_RD scal
Access level: 3
Can be changed: T
Unit group: -
Min
-
Description: Sets the signal source for scaling the ramp-down time of the ramp-function generator.
Dependency: Refer to: p1121
Note: The ramp-down time is set in p1121.
