17.2.3 How to use scale measurement function

(1) Selection of scale measurement function
The scale measurement function is set with the combination of basic setting parameters [Pr. PA01] and
[Pr. PA22].
(1) Operation mode selection
The scale measurement function can be used during semi closed loop system (standard control
mode). Set [Pr. PA01] to "_ _ 0 _".
(b) Scale measurement function selection
Select the scale measurement function. Select "1 _ _ _" (Used in absolute position detection system)
or "2 _ _ _" (Used in incremental system) according to the encoder you use.
(2) Selection of scale measurement encoder polarity
Select a polarity of the scale measurement encoder with the following "Encoder pulse count polarity
selection" of [Pr. PC27] as necessary.
[Pr. PA01]
1 0 0
[Pr. PA22]
0 0 0
Scale measurement function selection
0: Disabled
1: Used in absolute position detection system
2: Used in incremental system
POINT
"Encoder pulse count polarity selection" in [Pr. PC27] is not related to [Pr. PA14
Rotation direction selection]. Make sure to set the parameter according to the
relationships between servo motor and linear encoder/rotary encoder.
