2) MR-J4-_B_-RJ servo amplifier
You can connect the rotary encoder without using a branch cable shown in 1) for MR-J4-_B-RJ
servo amplifier. In addition, a four-wire type or A/B/Z-phase differential output rotary encoder can
also be used.

17.3.3 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].
(a) 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.

0: Disabled
1: Used in absolute position detection system
2: Used in incremental system

[Pr. PA22]
(2) Selection of scale measurement encoder communication method and polarity.
The communication method differs depending on the scale measurement encoder type. For the
communication method for using a linear encoder as scale measurement encoder, refer to "Linear
Encoder Instruction Manual". Select "Four-wire type" because there is only four-wire type for
synchronous encoder.
Select the cable to be connected to CN2L connector in [Pr. PC26].
000
[Pr. PC27]
Encoder pulse count polarity selection
0: Load-side encoder pulse increasing direction in the servo motor CCW
1: Load-side encoder pulse decreasing direction in the servo motor CCW
00
[Pr. PC26]
Load-side encoder cable communication method selection
0: Two-wire type
1: Four-wire type
When using a load-side encoder of A/B/Z-phase differential output method, set "0"
.
Incorrect setting will trigger [AL. 70] and [AL. 71].
Setting "1" while using an MR-J4-_B_ servo amplifier will trigger [AL. 37].
If the settings of the servo amplifier are unchanged from the factory settings and
communication with the controller is performed for the first time, this digit will be
automatically set according to the communication method of the connected
encoder cable.
