The G30 command positions the tool to the 2nd, 3rd, or 4th reference
position, via the specified intermediate point. It then sets the completion
signal for 2nd, 3rd, or 4th reference position return to 1.
Before issuing the G30 command, The 2nd, 3rd, or 4th reference position
must be set in parameter No. 1241, 1242, or 1243 with coordinates in the
machine coordinate system.
The tool moves to the intermediate point or 2nd, 3rd, or 4th reference
position at the rapid traverse rate.
Return to the 2nd, 3rd, or 4th reference position can be performed only
after the reference position has been established.
