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
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.
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.
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.
Description: Sets the initial rounding-off time for OFF3 for the extended ramp generator.
Description: Sets the initial rounding-off time for OFF3 for the extended ramp generator.
Description: Sets the final rounding-off time for OFF3 for the extended ramp generator.
