CAUTION
1 When ZCL (bit 2 of parameter No.1201) is set to 1
and an axis returns to the reference position by the
manual reference position return function, the
origin of the local coordinate system of the axis
matches that of the workpiece coordinate system.
The same is true when the following command is
issued:
G52α0;
α: Axis which returns to the reference position
2 The local coordinate system setting does not
change the workpiece and machine coordinate
systems.
3 Whether the local coordinate system is canceled at
reset depends on the parameter setting. The local
coordinate system is canceled when either CLR,
bit 6 of parameter No.3402 or RLC, bit 3 of
parameter No.1202 is set to 1. In
three-dimensional coordinate conversion mode,
however, the local coordinate system is not
canceled when D3R (bit 2 of parameter No. 5400)
is set to 1.
4 When a workpiece coordinate system is set with
the G92 (G50 for G code system A in the T series)
command, the local coordinate system is canceled.
However, the local coordinate system of an axis for
which no coordinate system is specified in a G92
(G50 for G code system A in the T series) block
remains unchanged.
5 G52 cancels the offset temporarily in cutter or tool
nose radius compensation.
6 Command a move command immediately after the
G52 block in the absolute mode.
