4. HOW TO USE THE POINT TABLE
(2) Absolute position linear encoder
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].
