Additional Manual
1 General
Each axis workpiece coordinate system preset signal presets a workpiece coordinate system
shifted by manual intervention, machine lock, etc. to the pre-shift workpiece coordinate
system by input signal.

[Data type] Bit
WTC When workpiece coordinate system preset is done, actual tool length offset is:
0 : Not considered.
1 : Considered.
When this paramter is set, the workpiece coordinate system preset by G-code, MDI
operation or input signal is done without cancelling the compensation modes. (cutter
compensation, tool length compensation and tool offset.)
The compensation vector is kept as the below figure when the workpiece coordinate system
preset is done to the coordinate shifted by amount of movement during manual intervention.
