1305 $MD_SAFE_MODULO_RANGE
Actual value range for SN for rotary axes
Unit: Default:
mdegree 0
Actual value range within which safe cams for rotary axes are calculated. The
axis must be a rotary axis ($MA_/$MD_SAFE_IS_ROT_AX = 1).
Value = 0:
Setting > 0 and multiples of 360 000 mdegrees:

Minimum value: Maximum value:
0 737 280 000
Modulo correction after +/- 2048 revolutions (i.e. after 737
280 000 mdegrees)
Modulo correction after this setting e.g. setting = 360 000
the actual value range is between 0 and 359.999 degrees,
a modulo correction is carried-out after every revolution.
