ZPI Coordinates at the reference position when a coordinate system is set
automatically
0 : Value set in parameter No. 1250 is used.
1 : For input in mm, the valueset in parameter1250 is used, or for input in
inches, the value set in parameter No. 1251 is used.
AWK Action taken after the workpiece zero point offset value is changed
0 : The absolute coordinate value is changed when the first automatic
operation is performed.
1 : The absolute coordinate value is changed immediately.(If automatic
operation is not in the start--up sequence)
NOTE
In either case, the change becomes effective when the next
block is buffered.

[Data type] Bit
EWD The shift direction of the workpiece coordinate system is:
0 : The direction specified by the external workpiece zero point offset
value
1 : In the opposite direction to that specified by the external workpiece
zero point offset value
EWD=0

EWS Shift value of the workpiece coordinate system and external workpiece
zero point offset value are
0 : Stored in the separate memory areas.
1 : Stored in the same memory area, that is, the shift and the offset values
are the same.
G50 When the CNC has commands G54 to G59 specifying workpiece
coordinate systems (optional function), if the G50 command for setting a
coordinate system (or the G92 command in G command system B or C) is
specified,
0 : The G50 (or G92) command is executed without an alarm.
1 : P/S alarm No. 010 is issued and the G50 (or G92) command is not
executed.
