14. USING A LINEAR SERVO MOTOR
14 - 16
(a) For the incremental linear encoder
POINT
For the incremental linear encoder, the magnetic pole detection is required
every time the power is turned on.
By turning on the servo-on command from the controller after the power-on, the magnetic pole
detection is automatically carried out. Therefore, there is no need to set the parameter (first digit of
[Pr. PL01]) for executing the magnetic pole detection.

Magnetic pole detection time (Note)
Note. The magnetic pole detection time indicates the operation time when FLS (Upper
stroke limit) and RLS (Lower stroke limit) are on.

on)

Note 1. When you turn off FLS (Upper stroke limit) or RLS (Lower stroke limit) during the magnetic pole detection, the operation of the
magnetic pole detection is carried on to the opposite direction. When both FLS and RLS are off, [AL. 27 Initial magnetic pole
detection error] occurs.
