Absolute coordinates after zero return is（0,0）；EXOF=(0,0) ； ZOFS1=(-10,-10);
Absolute coordinate values after zero return in G54: 0 - (-10 + 0) = 10;
Example 2：
Absolute coordinate values after zero return:（20,20）；EXOF=(5,5) ； ZOFS2=(10, 10);
Absolute coordinate values after zero return in G55: 20 - (10 + 5) = 5;
Example 3：
Current absolute coordinates (10,10); EXOF=(5,5) ; ZOFS1=(-10,-10); ZOFS2 =
(-30,-30); absolute coordinate values from G54 to G55: 10-（-30-（-10））= 30
EXOFS：external workpiece coordinate zero（it is added to zero offset value of each
workpiece
coordinate system, its value is a part of tool compensation->setting in the workpiece
coordinate
system）
ZOFSn：zero offset value of each workpiece coordinate system ZOFS1～ZOFS6（its value
is a
part of tool compensation->setting in the workpiece coordinate system）

Ⅰ Programming
Notes：
● When №11.7（APRS）is set to 0, the absolute coordinate system after machine zero
return is
not set, and the EXOF and ZOFSn offset cannot be executed because the workpiece
coordinate system is not set again.
● Modification setting of EXOFS and ZOFSn are valid only in non-run state, namely,
setting
values of each workpiece coordinate system cannot be modified when a program is
running.
● The workpiece coordinate system offset is immediately valid after values of EXOFS
and
ZOFSn are modified.
● Whether the incremental coordinates include offset values of the coordinate system is
set
by№05.1（PPD）.
● In tool nose radius compensation mode, compensation is cancelled temporarily in
G54~G59,
and is recovered in the next movement command.
● When G54~G59 and G50 are in the same block, G54~G59 are invalid, but G50 is
valid.
● When G50 sets the coordinate system, origin of the current workpiece system is
modified. So,
there is an offset value of origins between a new coordinate system set by G50 and
previously current coordinate system. The offset value should be added to offset values of
origins of all workpiece coordinate systems, i.e. all workpiece coordinate systems move
the same values, which are shown below: Offset value A are all workpiece coordinate
