Program Block

Comments

G10L2P1O1X-15.Z-10.;

defines work coordinate system zero

point to be at X-15, Z-10 from the

machine coordinate system zero point

G90;
G10L2P0O1X-15.Z-20.;

sets external offset of X-15, Z-20 moving

work coordinate system zero point to be

at X-30, Z-30 from the machine

coordinate system zero point

G90;
G10L2P0O1X-30.Z-30.;

sets external offset of X-30, Z-30 moving

work coordinate system zero point to be

at X-30, Z-30 from the machine

coordinate system zero point

Important: This modification is permanent. The new table values for the

work coordinate systems are saved even when control power is turned off.
