Absolute dimension programming along the shortest path (DC)
Example of DC: C=DC(60.3), general: axis name =DC(value)
Even if the rotary axis is not defined as a modulo axis, the axis can still be positioned with
DC (direct control). The response is the same as on a modulo axis.
Incremental programming (IC, G91)
Example of IC: C=IC(-532.4) , general: 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.
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.
