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 can be negative and ≥ +/-360°.
● 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.
12.3.4 Other programming features relating to rotary axes
Offsets
TRANS (absolute) and ATRANS (additive) can be applied to rotary axes.
Scalings
SCALE or ASCALE are not suitable for rotary axes, since the control always bases its modulo
calculation on a 360º full circle.
Preset actual value memory
PRESETON is possible.
Indexing axes
See Section "T1: Indexing axes (Page 771)".
