Parameters
11.2 Parameter list
Par. No. Name
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, and F07451
Note: The following applies for the setting of the standstill and positioning monitoring time:
Standstill monitoring time (p2543) ≤ positioning monitoring time (p2545)
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 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).
p2571 IPos maximum velocity
Description: Sets the maximum velocity for the "basic positioner" function (EPOS).
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:
p2571[1000 LU/min] = max_speed[rpm] x p29248/p29249 x p29247/1000
p2572 ** EPOS maximum acceler-
ation
Description: Sets the maximum acceleration for the "basic positioner" function (EPOS).
Dependency: Refer to: p2619
Note: The maximum acceleration appears to exhibit jumps (without jerk).
"Traversing blocks" operating mode:
The programmed acceleration override (p2619) acts on the maximum acceleration.
"Direct setpoint input/MDI" mode:
The acceleration override is effective (p2644, 4000 hex = 100%).
"Jog" and "search for reference" modes:
No acceleration override is active. The axis starts with the maximum acceleration.
p2573 ** EPOS maximum deceler-
ation
Description: Sets the maximum deceleration for the "basic positioner" function (EPOS).
Dependency: Refer to: p2620
