Description: System variable/value range/index
$AA_IEN[X]
Actual value in the settable origin system (SOS).
Axes: Channel axis
$AA_IBN[X]
Actual value in the basic origin system (BOS).
Axes: Channel axis
$AA_IB[X]
Actual value in basic coordinate system (BCS)
Axes: Channel axis
$AA_IM[X]
Actual value in machine coordinate system (MCS).
Axes: GEOAX, channel axis, machine axis
$AA_ACT_INDEX_AX_POS_NO[X]
0: No indexing axis, therefore no indexing position available.
> 0: Number of indexing position last reached or crossed
Axes: Geometry axis, channel axis, machine axis
$AA_PROG_INDEX_AX_POS_NO[X]
0: Not an indexing axis, therefore no indexing position available or
the indexing axis is not currently approaching an indexing position
> 0: Number of programmed indexing position
Axes: Geometry axis, channel axis, machine axis
$AA_ENC_ACTIVE[X]
Active measuring system is operating below encoder limit frequency
Axes: Geometry axis, channel axis, machine axis
$AA_ENC1_ACTIVE[X]
Encoder 1 is operating below encoder limit frequency
Axes: Geometry axis, channel axis, machine axis
$AA_ENC2_ACTIVE[X]
Encoder 2 is operating below encoder limit frequency
Axes: Geometry axis, channel axis, machine axis
