| | | 5.1.5 Axes programming through parameters AA, AB, AC The system parameters AA, AB and AC are very useful for parametric programming (like macros or fixed cycles). These parameters represents respectively the first (AA), the second(AB) and the third(AC) axis specified with G25. For example, with G25XYZ, the parameter AA represents the axis X, parameter AB the Y axis and AC the Z axis. Through these parameters it is thus possible to program axes movements independently from the real axes names. By programming G25 the axis related to AA, the one related to AB and the one related to AC are specified, as shown in the following diagram: | | |
