In this example, the final setting value of [Pr. PL09] is 49 (Setting value at the alarm occurrence = 70

× 0.7).

14.3.3 Home position return

POINT

The incremental linear encoder and the absolute position linear encoder have

different reference home positions at the home position return.

(1) Incremental linear encoder

CAUTION

If the resolution or the stop interval (the third digit of [Pr. PL01]) of the linear

encoder is large, it is very dangerous since the linear servo motor may crash into

the stroke end.

(a) When the linear encoder home position (reference mark) exists in the home position return direction

When an incremental linear encoder is used, the home position is the position per 1048576 pulses

(changeable with the third digit of [Pr. PL01]) with reference to the linear encoder home position

(reference mark) passed through first after a home position return start. Change the setting value of

[Pr. PL01] according to the linear encoder resolution.
