Absolute position linear encoder
The data set type home position return can also be carried out.
When an absolute linear encoder is used, the reference home position is the position per 1048576 pulses (changeable with
the third digit of [Pr. PL01]) with reference to the linear encoder home position (absolute position data = 0).
In the case of a proximity dog type home position return, the nearest reference home position after proximity dog off is the
home position. The linear encoder home position can be set in any position. LZ (Encoder Z-phase pulse) is outputted based
on "Stop interval selection at the home position return" in [Pr. PL01].
