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

U32 IM T
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.

U32 IM T
Description: Sets the maximum deceleration for the "basic positioner" function (EPOS).
Dependency: Refer to: p2620
Note:
The maximum deceleration appears to exhibit jumps (without jerk).
"Traversing blocks" operating mode:
The programmed deceleration override (p2620) acts on the maximum deceleration.
"Direct setpoint input/MDI" mode:
The deceleration override is effective (p2645, 4000 hex = 100%).
"Jog" and "search for reference" modes:
No deceleration override is effective. The axis brakes with the maximum deceleration.

U32 IM T, U
Description: Sets the jerk limiting.
Dependency: Refer to p2572, p2573, and p2575
Note: The jerk limiting is internally converted into a jerk time as follows:
Jerk time Tr = max(p2572, p2573)/p2574
