Description: Sets the signal source for accepting the setting value of the ramp-function generator.
Dependency: The signal source for the ramp-function generator setting value is set using parameters.
Refer to: p1144
Note: 0/1 signal:
The ramp-function generator output is immediately (without delay) set to the setting value of the ramp-function gen-
erator.
1 signal:
The setting value of the ramp-function generator is effective.
1/0 signal:
The input value of the ramp-function generator is effective. The ramp-function generator output is adapted to the
input value using the ramp-up time or the ramp-down time.
0 signal:
The input value of the ramp-function generator is effective.
Description: Sets the signal source for the ramp-function generator setting value.
Dependency: The signal source for accepting the setting value is set using parameters.
Refer to: p1143
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.
