This section describes the following operations when tool position offset
is applied: G53, G28, G30, and G30.1 commands, manual reference
position return, and the canceling of tool position offset with a T00
command.
Executing reference position return (G28) or a G53 command when tool
position offset is applied does not cancel the tool position offset vector.
The absolute position display is as follows, however, according to the
setting of bit 4 (LGT) of parameter No. 5002.
LGT = 0 (Tool geometry compensation is based on shift of the coordinate system.)

The shift is reflected. Coordinates
shifted according to the tool geom-
etry compensation are displayed.
The vector is not reflected. The
coordinates are displayed as if the
offset had been temporarily can-
celed.
Next block Coordinates shifted according to
the tool geometry compensation
are displayed.
The vector is reflected.
LGT = 1 (Tool geometry compensation is based on tool movement.)

NOTE
Bit 6 (DAL) of parameter No. 3104 is set to 0 (the actual positions to which the tool position offset
is applied are displayed in the absolute position display).
