Linear Encoder And Branch Cable - Mitsubishi Electric MELSERVO-J3W Series Instruction Manual

13. USING A LINEAR SERVO MOTOR

13.3.2 Linear encoder and branch cable

The CN2A/CN2B connector has the thermistor signal pins for the linear servo motor. To output the thermistor
signal, create a branch cable.
(1) Configuration diagram
The following shows the configuration diagram of the servo amplifier and the linear encoder. The
configuration of the encoder cable differs according to the linear encoder. For the encoder cable, refer to
section 3.1 in the MR-J3- B-RJ004 Instruction Manual.

(2) Production of branch cable
Produce the branch cable using the MR-J3THMCN2 connector set as shown below. Keep the branch cable
length 0.5m or shorter. Use the AWG22 cable for the wiring.
