Description: Display and connector output for the actual following error.
This value is the deviation between the position setpoint - after fine interpolation - and the position actual value.
Notice: When speed precontrol is active (p2534 > 0 %), the following applies:
To calculate this value, the position setpoint is delayed by two position controller clock cycles.
When speed precontrol is inactive (p2534 = 0 %), the following applies:
To calculate this value, the position setpoint is delayed by two position controller clock cycles.

CU250S_V_PN
(Position control)
Description: Sets the moment of inertia for the torque precontrol.
Dependency: Refer to: p2534, r2564
Note: When calculating the torque precontrol value (r2654), the time derivation of the speed precontrol value is multiplied
by 2 PI * p2567.
For reasons associated with the compatibility to earlier firmware versions, the factory setting for p2567 = 1 kgm^2/2
PI. This means that CO: r2564 remains as standard the derivation over time of the speed precontrol value and is
referred, as before, to a moment of inertia of 1 kgm^2/2 PI. For torque precontrol, the moment of inertia can now be
directly entered into p2567 (instead of subsequently evaluating the precontrol value.
