When fabricating encoder cables, note the descriptions in this section, in order to ensure the reliability of communication.
Fabricate cables with the following procedure.
1.
Selection of connectors
• Check the cable clamp size.

• Obtain the specification, wiring guide for the connector, and other documents from the manufacturer.
• Purchase assembly jigs and similar parts as necessary.
2.
Selection of cables
• Select a recommended wire described in chapter 5. For the MR-J3ENSCBL_M-_ (10 m or less), a recommended wire or
equivalent wires can be used.
• Select a shielded cable.
• Select a cable with a diameter that can be clamped with the connector cable clamp.
• Select a cable whose length, diameter, and flex type are appropriate.
3.
Assembly of the cable
• Check the wiring guide of the connector manufacturer, then connect the connector properly.
• Check internal wiring described in chapter 5 to connect it properly.
• Perform a shielding process on the encoder cable properly.
• Do not connect anything to unused pins.
• When wiring the CN2, CN2A, CN2B, and CN2C side connectors, connect the external conductor of the shielded cable to
the ground plate and fix it to the connector shell.
• When wiring the connector on the rotary servo motor-side, connect the external conductor of the shielded cable to the SHD
terminal.
• Check if the pin arrangement is correct.
• Connect the twisted pair cable using the correct combination.
• Check if the number of pairs of P5/LG wiring connected in parallel is correct.
• Fix the cable to the connector with a proper clamping torque.
4.
Inspection
• After assembly, perform conduction, insulation, and other inspections to check if the connection is correct.
• Check the surface for scratches and contamination.
• Check the connector pins for distortions, bending, dents, and other problems.
• Check the connector pins for foreign matter adhesion, contamination, and discoloration.
