Speed Ripple Compensation Warnings

The speed ripple compensation value is specific to each Servomotor. If you replace the Servo-
motor while speed ripple compensation is enabled, an A.942 warning (Speed Ripple Compen-
sation Information Disagreement) will occur to warn you.
If an A.942 warning occurs, either reset or disable speed ripple compensation from the Sig-
maWin+.

You can also disable detection of this warning with the following parameter.
