p1134[0...n] Ramp-function generator rounding-off type / RFG round-off type
Access level: 2
Can be changed: U, T
Units group: -
Min
0
Description: Sets the smoothed response to the OFF1 command or the reduced setpoint for the extended ramp-function gener-
ator.
Value: 0:
1:
Dependency: No effect up to initial rounding-off time (p1130) > 0 s.
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 com-
pleted. 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 set-
point.
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
PM230 Access level: 2
Can be changed: C(1), U, T
Units group: -
Min
0.000 [s]
Description: Sets the ramp-down time from the maximum speed down to zero speed for the OFF3 command.
Dependency: The parameter is pre-assigned depending on the size of the power unit.
Note: This time can be exceeded if the DC link voltage reaches its maximum value.
p1135[0...n] OFF3 ramp-down time / OFF3 t_RD
PM240 Access level: 2
PM250, PM260
Can be changed: C(1), U, T
Units 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
PM230 Access level: 3
Can be changed: U, T
Units group: -
Min
0.000 [s]
Description: Sets the initial rounding-off time for OFF3 for the extended ramp generator.
