The following table shows the possible settings for the operands.
Operand
Axis names
M code
D code
Stopover Axes
Coordinate data 0 to 39999999
Note Refer to 7-4 M Code Outputs for details on M codes, and to 7-4-9 D Code Out-
puts for details on D codes. Refer to 7-4-10 Stopover Function for details on

This command moves the specified axes to the workpiece origin by PTP con-
trol. The coordinate system and mode settings will be as follows after the
return to the workpiece origin:
1. The coordinate system will be set to the workpiece coordinate system.
2. The command mode will be set to absolute specification.
3. The operating mode will be set to Pass Mode.
The settings will not be switched to the ones above if the G27 command is ter-
minated while in progress by the OPTIONAL END command (G74), FORCED
BLOCK END, or other command. The command is also considered to be in
progress while waiting for the M code reset.
