12.3 Programming rotary axes

Incremental programming (IC, G91)

Example for positioning axis: POS[axis name] = IC(+/-value)

When programming with incremental dimensions, the rotary axis traverses across the same

path as with the modulo axis. In this case, however, the traversing range is limited by the

software limit switches.

● The value identifies the rotary-axis traversing distance.

● The value's sign unequivocally defines the rotary-axis traversing direction.

Limited traversing range

The traversing range is limited as with linear axes. The range limits are defined by the "plus"

and "minus" software limit switches.
