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