10.1.7 Local Coordinate System

This function is for assigning a coordinate system on the workpiece coordinate system now being selected.
This enables the workpiece coordinate system to be changed temporarily.
The local coordinate system can be selected independently on each workpiece coordinate system G54 to
G59.
G54 G52
G55 G52
G56 G52
G57 G52
G58 G52
G59 G52
The command format of the local coordinate system is given below.
(G54) G52 Xx1 Yy1 Zz1 ;
(G54)
G52
Xx1,Yy1,Zz1
The local coordinate zero points are provided as distances from the zero point of the designated workpiece
coordinate system (local coordinate offset).
In the incremental position setting mode, the position obtained by adding the local coordinate offset amount
to the previously specified offset amount serves as the new local coordinate zero point.
If no workpiece coordinates are designated, the local coordinates will be created on the currently selected
workpiece coordinates.
This command is unmodal but the local coordinate system created by G52 is valid until the next G52
command is issued.
The local coordinate system is canceled by the input of the reset signal or by manual or automatic dog-type
reference position return.
