0.0
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 runs-up at the torque/force limit.
Recommenda- p1145 = 0.0:
tion: This value de-activates the ramp-function generator tracking.
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 at run-up.
p1145 > 1.0:
The greater the value, the higher the permissible deviation between the speed setpoint and speed actual value.
Note: In the V/f mode, the ramp-function generator tracking is not active.
For SERVO with V/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.
