B-63943EN-1/02 1.AXIS CONTROL
- 171 -
CAUTION
1 When ZCL (bit 2 of parameter No.1201) is set to 1
and an axis returns to the reference point by the
manual reference point return function, the zero
point of the local coordinate system of the axis
matches that of the work coordinate system. The
same is true when the following command is
issued:
G52α0;
α: Axis which returns to the reference point
2 The local coordinate system setting does not
change the workpiece and machine coordinate
systems.
3 Whether the local coordinate system is canceled
upon reset depends on the specified parameters.
The local coordinate system is canceled upon reset
when 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 G code command for coordinate system setting
(G92 <M series> , G50 <T series> (G92 with G
code system B/C for T series)), the local coordinate
system is canceled. However, the local
coordinate system of an axis for which no
coordinate system is specified in a G code block for
coordinate system setting 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.
