Cause : Check modulo value for safe position via PROFIsafe comes when parameterizing the modulo value for safe position via PROFIsafe (p9505) the position actual value can jump when the range that can be represented overflows.

Range that can be represented:
- 32-bit value: +/- 2048 revolutions
- 16-bit value: +/- 2048 revolutions (depending on p9574)

1. Correct the parameter assignment.
2. Set p9505 to 2^n revolutions - and to complete revolutions (i.e. a multiple of 360 °).
