Note: Applications:
Motion at zero setpoint and dominant stiction can be suppressed but this has a negative impact on the remaining
setpoint-actual value difference. This can be used, for example, to avoid oscillation of a position-controlled axis at
standstill (stick-slip effect) or overshoot when traversing (moving) in micrometer steps.
Also prevents tension/stressing for axes that are mechanically and rigidly coupled with one another (e.g. for syn-
chronous spindles, master - slave axes).
Description: Sets the time constant of the PT1 filter for integrator feedback.
The integrator of the speed/velocity controller is re-parameterized to become a PT1 filter through a feedback ele-
ment (1st Order low pass filter characteristics).
The following applies:
p1494 < 0.25 (2 * p0115[1]) --> the PT1 filter is not active - the pure integrator is effective.
p1494 >= 0.25 (2 * p0115[1]) --> the PT1 filter is active and has replaced the pure integrator.

Description: Sets the signal source for the acceleration pre-control.
Dependency: The signal source for the acceleration is activated with p1400.2 = 1.
For p1400.2 = 0, the acceleration pre-control is calculated from the speed setpoint change from r0062.
For p1400.2 = 0 and activate reference model (p1400.3 = 1) the acceleration pre-control is switched-out.
Refer to: p1400, p1496
Note: If the acceleration is entered as external signal, then the accelerating torque is calculated as follows (r1518):
r1518 = acceleration (% of p2007) / 100 % * (p2007 * 60 s) / p0311 * r0345 / 1 s * r0333
Description: Sets the scaling for the acceleration pre-control of the speed/velocity controller.
