Mitsubishi MR-JE-100A - Multi-Drop Method (RS-422 Communication)

5. HOW TO USE THE PROGRAM
5 - 60
5.5.2 Multi-drop method (RS-422 communication)
The RS-422 communication function enables to operate multiple servo amplifiers on the same bus. In this
method, set station Nos. to the servo amplifiers so that the controller recognizes which servo amplifier is
receiving the data currently being sent. Set the station Nos. with [Pr. PC20 Station number setting].
Be sure to set one station No. to one servo amplifier. Setting one station No. to multiple servo amplifiers will
disable a normal communication. When operating multiple servo amplifiers with one command, use the
group specification function mentioned in section 5.5.3. For the cable connection, refer to section 12.1.1 (2)
of "MR-JE-_A Servo Amplifier Instruction Manual".
