4. DESCRIPTION OF PARAMETERS
49
NOTE
If bit 2 (D3R) of parameter No. 5400 is set to 1, this parameter
setting is ignored in the three–dimensional coordinate
conversion mode. A reset does not cause the workpiece
coordinate system to be returned to that specified with G54.

[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 : G50 is executed and no alarm is issued.
1 : G50 is not executed and a P/S alarm (No. 010) is issued.
RLC Local coordinate system is
0 : Not cancelled by reset
1 : Cancelled by reset
G52 In local coordinate system setting (G52), a cutter compensation vector is:
0 : Not considered.
1 : Considered.
