<strong>11</strong>.03 3 Variables3.5 Axis status data3.5.4 Area C, Mod. SEGA: State data: Geometry axes in tool offsetmemory (extension of SGA)OEM-MMC: Linkitem/Channel/GeometricAxis/...All status data that are dependent on machine movement and specified in theworkpiece coordinate system are combined in module SGA. Supplementaryinformation can be found in module SEGA. The individual variables are definedas arrays where the line index is the number of the axis (assigned to the currentchannel).The variable "name" in module SGA with the line index in questionidentifies the axis.The assignment of the line indices in modules SGA and SEGA is identical.With SW 5.2 and later, OPI modules SGA and SEGA can be addressed via thegeo-axis no. instead of via the channel axis no.:Line index 1001: 1st geo-axisLine index 1002: 2nd geo-axisLine index 1003: 3rd geo-axisThe number of channel axes (geometry, special axes and spindles) can befound in "numMachAxes" in module Y in area C.aaDelt$AA_DELT[x] x = AxisStored axial distance-to-go in the WCS after axial delete-distance-to-go DELDTG(axis) for synchronous actions (Note:for SYNACT only)- DoubleMulti-line: yes Axis index numMachAxesaaDtbw$AA_DTBW[x] x = AaxisAxial distance from the beginning of the block in the WCS for positioning and synchronous axes for synchronousmotion (Note: for SYNACT only)- DoubleMulti-line: yes Axis index numMachAxesaaDtepw$AA_DTEPW[x] x = AxisAxial distance-to-go for infeed during oscillation in the WCS (Note: for SYNACT only)- DoubleMulti-line: yes Axis index numMachAxesaaDtew$AA_DTEW[x] x = AxisAxial distance to the end of the block in the WCS for positioning and synchronous axes for synchronous actions (Note:for SYNACT only)- DoubleMulti-line: yes Axis index numMachAxesaaMw$AA_MW[x] x = AxisLatched probe position retransformed in the WCS- DoubleMulti-line: yes Axis index numMachAxes© Siemens AG, <strong>2003</strong>.
