3.1 Parts identification
*1 For the 2-axis drive unit and 3-axis drive unit.
*2 For the 3-axis drive unit.
*3 For the 1-axis drive unit.
■
External encoder connector
The following table shows the communication method of the external encoder compatible with the drive units.
*1 The MR-J4FCCBL03M branch cable is required.
*2 If the external encoder communication method is the four-wire type, the MR-J5D2-_G_ cannot be used. Use MR-J5D1-_G_.

*2
C-axis encoder connector (CN2C) Connect the C-axis servo motor encoder or external encoder.
(20)
*3
External encoder connector (CN2AL) Connect the external encoder.
(21) Battery connector (CN4) This is a connector to connect the battery for absolute position
data backup. When the servo motor with a batteryless absolute
position encoder is being used, it does not need to be connected
to the battery for absolute position data backup. 
(22) USB communication connector (CN5) Connect with a personal computer.
