For a rotary axis, the internal position actual value calculation limits the
maximum modulo value with which a drive can be parameterized.
The following inter–relationship exists:
F in the following is a conversion factor which depends on the dimen-
sion system:

From SW 1.6, the following applies:
When changing P1, P2 or P3, a check is automatically made in the
drive as to whether these three parameter values fulfill the appropriate
formula. If the modified value lies outside the valid range, then the drive
rejects it and the old value is kept.
