Functions and configuration
Outline
The following shows the differences between the linear servo motor and the rotary servo motor.
Category Item Differences Remark
Linear servo motor Rotary servo motor
Servo motor
magnetic pole
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].
