The bits below are defined for the following spindles. They do not affect the following spindles,
only the active leading axes which belong the to GI grouping defined by the following spindle.
The above values are included when calculating the synchronous position (G403).
Bit 5 Bit 5=1 Include tool length compensations for GI position calculation
Bit 5=0 Do not include tool length compensations
Circle radius compensations are never included in calculations.
Bit 4 Bit 4=1 Include programmable ZO offset (G58...G59) for GI position calculations
Bit 4=0 Do not include programmable ZO offset
Bit 3 Bit 3=1 Include external ZO for GI position calculations
Bit 3=0 Do not include external ZO
Bit 2 Bit 2=1 Include ZO (G54...G57) for GI position calculations
Bit 2=0 Do not include ZO (G54...G57)
Bit 1 Bit 1=1 Include DRF and preset for GI position calculations
Bit 1=0 Do not include DRF and preset
Bit 0 Reference system GI positions
Bit 0=1 The positions have been entered in the workpiece system; include offsets
as for bits 2..5 in calculation
Bit 0=0 Positions have been entered in machine system; do not include any offsets
in calculation
