Description: Sets the standstill window for the standstill monitoring function.
After the standstill monitoring time expires, it is cyclically checked whether the difference between the setpoint
and actual position is located within the standstill window and, if required, an appropriate fault is output.
Value = 0: The standstill monitoring is deactivated.
Dependency: Refer to: p2543, p2544, and F07450
Note: The following applies for the setting of the standstill and positioning window:
Standstill window (p2542) ≥ positioning window (p2544)

Description: Sets the standstill monitoring time for the standstill monitoring function.
After the standstill monitoring time expires, it is cyclically checked whether the difference between the setpoint
and actual position is located within the standstill window and, if required, an appropriate fault is output.
Dependency: Refer to: p2542, p2545, and F07450
Note: The following applies for the setting of the standstill and positioning monitoring time:
Standstill monitoring time (p2543) ≤ positioning monitoring time (p2545)

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.

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, and 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).

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 deactivated.
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).

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.
