Executing manual reference position return 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.)
