Note 1. Refer to section 9.1 for the connection of a manual pulse generator.
2. This diagram shows sink I/O interface. For source I/O interface, refer to section 3.9.3 of "MR-JE-_A Servo Amplifier Instruction
Manual".
3. 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.
4. To use the RS-422/RS-485 communication function, connect between TRE and RDN of the final axis servo amplifier. (Refer to
section 12.1.1 of "MR-JE-_A Servo Amplifier Instruction Manual").
