Note 1. Signal can be assigned for these pins with controller setting.
For contents of signals, refer to the instruction manual of controller.
2. For sink I/O interface. For source I/O interface, refer to section 3.7.3 of the MR-J3-
B Servo Amplifier Instruction Manual.
3. Speed, position and temperature of the direct drive motor are detected.
4. To configure the absolute position detection system, always connect this by combining with the MR-J3BAT battery. (Refer to
section 9.2.)
5. Fabrication of the encoder cable is required at user side. (Refer to section 9.1.2.)
