SINAMICS G130/G150
308 List Manual (LH2), 04/2014, A5E03263479A
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.
Recommend.: If at least one speed setpoint filter/velocity setpoint filter is activated (p1414), then the ramp-function generator
tracking should be deactivated (p1145 = 0.0). When the speed setpoint filter is activated, the output value of the
ramp-function generator can no longer be tracked (corrected) corresponding to the maximum possible drive
acceleration.
Re p1145 = 0.0:
This value de-activates the ramp-function generator tracking.
Re p1145 = 0.0 ... 1.0:
Generally, these values are not practical. They cause the motor to accelerate below its torque limit. The lower the
selected value, the greater the margin between the controller and torque limit when accelerating.
Re p1145 > 1.0:
The greater the value, the higher the permissible deviation between the speed setpoint and speed actual value.
Notice: If ramp-function generator tracking is activated and the ramp time is set too short, this can cause unsteady
acceleration.
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.
For SERVO with U/f operation, the following applies:
The complete ramp-function generator is not active, i.e. ramp-up and ramp-down time = 0.
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.
