12.3 Programming rotary axes

Application
By approximating the two following machine data, indexing positions of modulo indexing
axes can be implemented in the same way as for the modulo range (see also Section "T1:
Indexing axes (Page 771)").
MD30503 $MA_INDEX_AX_OFFSET
MD30340 $MA_MODULO_RANGE_START

MD30310
Axis-specific machine data
MD30310 ROT_IS_MODULO (modulo conversion for rotary axis)
is used to define whether the rotary axis behaves as a linear axis during programming and
positioning or whether rotary-axis special features are taken into account.
These features and any differences (mainly with respect to absolute programming) are
explained on the following pages.
12.3.2

Rotary axis with active modulo conversion (continuously-turning rotary axis).

Activate modulo conversion
→ Set MD30310 $MA_ROT_IS_MODULO = 1.
Note
With modulo axes, it is advisable to set the position display to modulo 360º (set MD30320
$MA_DISPLAY_IS_MODULO = 1).
