Ramp-function generator rounding-off type / RFG round-off type

VECTOR_G Can be changed: U, T
Data type: Integer16
P-Group: Setpoints
Not for motor type: -
Min
0
Description: Sets the smoothed response to the OFF1 command or the reduced setpoint for the extended ramp-function
generator.
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
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.

OFF3 ramp-down time / OFF3 t_RD

VECTOR_G Can be changed: C2(1), U, T
Data type: FloatingPoint32
P-Group: Setpoints
Not for motor type: -
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.
