CN3-3
CN3-16
The encoder output pulses set in [Pr. PA15] and [Pr. PA16] are output in differential line
driver type.
In CCW rotation of the servo motor, the encoder B-phase pulse lags the encoder A-
phase pulse by a phase angle of
π /2.
The relation between rotation direction and phase difference of the A-phase and B-
phase pulses can be changed with [Pr. PC03].
Output pulse specification, dividing ratio setting, and electronic gear setting can be
selected.
These signals cannot be used for MR-J4W3-_B.

Function and application
Digital I/F power input DICOM CN3-23 Input 24 V DC (24 V DC ± 10% MR-J4W2-_B: 350 mA, MR-J4W3-_B: 450 mA) for I/O
interface. The power supply capacity changes depending on the number of I/O interface
points to be used.
For sink interface, c of 24 V DC external power supply.
For source interface, connect - of 24 V DC external power supply.
Digital I/F common DOCOM CN3-26 Common terminal for input device such as EM2 of the servo amplifier. This is separated
from LG.
For sink interface, connect - of 24 V DC external power supply.
For source interface, c of 24 V DC external power supply.
Control common LG CN3-14 This is for encoder output pulses (differential line driver).
Shield SD Plate Connect the external conductor of the shielded wire.
