With the CC 61xx or CC 424 you can also use this function without active IPC.
A prerequisite for the activation of the possibility of compensation with the
CC 422 is an active and already adjusted IPC (Integral Phase Compensation).

Enter the following test program:
BEARBEITUNG [MACHINING]

N1 G0 X400
N2 G0 X0
N3 M99

 Run the program at high speed.
 Use the integrated oscilloscope to record the following error.

CC 424: Adjust MP_compIpcJerkFact until a minimal following error occurs
in the jerk phase. Here you can compensate the following error for the jerk
phase.
Typical input values: 0 to 0.5 (e.g. 0.01).
Note
Please note that values over 0.5 in MP_compIpcJerkFact do not make
sense for the CC 424 controller unit, and are therefore not permissible.
Therefore, an error message will be issued for values greater than 0.5.
 CC 422: Adjust MP_compIpcJerkFact until a minimal following error occurs
in the jerk phase. Here you can compensate positive following errors
(MP_compIpcJerkFact > 1) as well as rare negative following errors
(MP_compIpcJerkFact < 1) for the jerk phase.
Typical input values: 0.5 to 2.
