Note 1. Signal can be assigned for these pins with the controller setting.
For contents of signals, refer to the instruction manual of the controller.
2. The signal cannot be used in the speed control mode and torque control mode.
3. This diagram shows sink I/O interface. For source I/O interface, refer to section 3.8.3.
4. This is for MR-J4-_B_-RJ servo amplifier. MR-J4-_B_ servo amplifier does not have CN2L connector.
5. The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they
can be configured by one.
6. Refer to table 1.1 for connections of external encoders.
