(2) Fabrication of the encoder cable
Produce the load-side encoder cable using MR-J3CN2 or a junction connector as shown below. The
encoder cable can be produced as the length of maximum 30 m.

2. For the CN2L connector, signals of pin 3 and pin 4 will be as follows.
Pin 3: MR2
Pin 4: MRR2
3. Do not connect anything to the pins shown as
. Especially, pin 10 is for manufacturer
adjustment. If it is connected with any other pin, the servo amplifier cannot operate normally.
Referring POINT of chapter 1, securely connect the external conductor of the shielded cable to
the ground plate and fix it to the connector shell.
