2.2 List of parameters
Recommendation: 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.
For p1145 = 0.0:
This value deactivates the ramp-function generator tracking.
For 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.
For 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:
- deactivate 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 ramp-function generator tracking and active acceleration model (p1400.20, 23), the integral component of the
speed controller should be able to run freely up to the torque limit (p1400.16 = 1).
p1148[0...n] Ramp-function gen. tolerance for ramp-up and ramp-down active / RFG tol HL/RL act
VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Setpoints
Not for motor type: -
Min
0.000 [rpm]
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.
