WARNING
1 When 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 If coordinate values are not specified for all axes when setting a workpiece coordinate system
with the G92 command, the local coordinate systems of axes for which coordinate values were
not specified are not cancelled, but remain unchanged.
4 G52 cancels the offset temporarily in cutter compensation.
5 Command a move command immediately after the G52 block in the absolute mode.
6 If parameter CLR (No. 3402#6) is set in such a manner that NC is cleared by reset, the local
coordinate system is cancelled by reset.
7If X–axis or Y–axis was not commanded by G52 command, the local coordinate system of the
un–commanded axis remains unchanged as before.
If X–axis or Y–axis was not commanded by G92 command, the local coordinate system of the
uncommanded axis remains unchanged as before, and it is not cancelled.
8 The M, S or T code cannot be commanded in the same block as G52 command block.
9 The incremental command in a block just after G52 does not produce the incremental amount
from the present position of the tool at that time, but it produces the incremental amount from
the zero point of the set local coordinate system.
Provided that the incremental amount from the present position of the tool can be produced by
parameter LIP (No. 16201#0) setting.
