Description: Displays the total speed setpoint
This value is obtained from the sum of the speed pre-control and position controller output.
Dependency: Refer to: r2560, r2561
Description: Displays the dynamic following error.
This value is the deviation, corrected by the velocity-dependent component, between the position setpoint and the
position actual value.
Note: For p2534 >= 100 % (pre-control activated) the following applies:
The dynamic following error (r2563) corresponds to the system deviation (r2557) at the position controller input.
For 0 % < p2534 < 100 % (pre-control activated) or p2534 = 0 % (pre-control de-activated) the following applies:
The dynamic following error (r2563) is the deviation between the measured position actual value and a value that is
calculated from the position setpoint via a PT1 model. This compensates the system-related velocity-dependent
system deviation for a P controller.
Description: Displays the torque pre-control value.
Dependency: Refer to: p1511, p1512
Note: The torque pre-control value is the derivation over time of the speed pre-control value and is referred to a moment
of inertia of 1 kgm^2/2 PI. When using the pre-control, then this should be evaluated corresponding to the actual
moment of inertia.
Description: Displays the actual following error.
This value is the deviation between the position setpoint - after fine interpolation - and the position actual value.
Notice: When speed pre-control is active (p2534 > 0 %), the following applies:
To calculate this value, the position setpoint is delayed by two position controller clock cycles.
When speed pre-control is inactive (p2534 = 0 %), the following applies:
To calculate this value, the position setpoint is delayed by two position controller clock cycles.
