SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011
Description: Sets the ramp-function generator tracking.
The output value of the ramp-function generator is tracked (corrected) corresponding to the maximum possible
drive acceleration. The reference value is the deviation at the speed/velocity controller input that is necessary to
ensure that the motor accelerates at the torque/force limit.
Notice: If ramp-function generator tracking is activated and the ramp time is set too short, this can cause unsteady acceler-
ation.
Remedy:
- switch off ramp-function generator tracking (p1145 = 0).
- increase the ramp-up/ramp-down time (p1120, p1121).
Note: In the U/f mode, ramp-function generator tracking is not active.
Description: Sets the tolerance value for the status of the ramp-function generator (ramp-up active, ramp-down active).
If the input of the ramp-function generator does not change in comparison to the output by more than the entered
tolerance time, then the status bits "ramp-up active" and "ramp-down active" are not influenced.
Dependency: Refer to: r1199
Description: Displays the acceleration of the ramp-function generator.
Dependency: Refer to: p1145
Description: Displays the setpoint at the output of the ramp-function generator.
