Not required Automatically executed at the first servo-on after
(default setting) the power is turned on.
For the absolute position linear encoder, [Pr. PL01]
can disable the magnetic pole detection. The timing
of the magnetic pole detection can be changed with
[Pr. PL01].

encoder
One servo motor Home position return pitch can be changed with
revolution unit parameter setting.
