Parameters
10.2 Parameter list
Par. No. Name
p2544 * LR positioning window
Description: Sets the positioning window for the positioning monitoring function.
After the positioning monitoring time expires, it is checked once as to whether the difference between the
setpoint and actual position lies within the positioning window and if required an appropriate fault is output.
Value = 0 --> The positioning monitoring function is de-activated.
Dependency: Refer to F07451.
Note: The following applies for the setting of the standstill and positioning window:
Standstill window (p2542) ≥ positioning window (p2544)
p2545 * LR positioning monitoring
time
Description: Sets the positioning monitoring time for the positioning monitoring.
After the positioning monitoring time expires, it is checked once as to whether the difference between the
setpoint and actual position lies within the positioning window and if required an appropriate fault is output.
Dependency: The range of p2545 depends on p2543.
Refer to: p2543, p2544, F07451
Note: The tolerance bandwidth is intended to prevent the dynamic following error monitoring incorrectly re-
sponding due to operational control sequences (for example, during load surges).
p2546 * LR dynamic following
error monitoring tolerance
Description: Sets the tolerance for the dynamic following error monitoring.
If the dynamic following error (r2563) exceeds the selected tolerance, then an appropriate fault is output.
Value = 0 --> The dynamic following error monitoring is de-activated.
Dependency: Refer to r2563, F07452
Note: The tolerance bandwidth is intended to prevent the dynamic following error monitoring incorrectly re-
sponding due to operational control sequences (e.g. during load surges).
p2571 IPos maximum velocity
Description: Sets the maximum velocity for the "basic positioner" function (IPos).
Note: The maximum velocity is active in all of the operating modes of the basic positioner.
The maximum velocity for the basic positioner should be aligned with the maximum speed/velocity of the
speed/velocity controller.
p2572 ** IPos maximum accelera-
tion
Description: Sets the maximum acceleration for the "basic positioner" function (IPos).
Note: The maximum acceleration appears to exhibit jumps (without jerk).
"Traversing blocks" operating mode:
The programmed acceleration override acts on the maximum acceleration.
"Direct setpoint input/MDI" mode:
The acceleration override is effective.
"Jog" and "search for reference" modes:
No acceleration override is active. The axis starts with the maximum acceleration.
