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

are the same.
G50 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.

This is one of the parameters that give the position of workpiece
coordinate system (G54 to G59). It gives an offset of the workpiece zero
point common to all workpiece coordinate systems. In general, the offset
varies depending on the workpiece coordinate systems. The parameter
value can also be set from the PMC by using the external data input
function.
