Mitsubishi General-Purpose Ac Servo Protocol Communication Function - Mitsubishi Electric MR-J4 Instruction Manual

18. MR-J4-03A6 SERVO AMPLIFIER

18.9 Mitsubishi general-purpose AC servo protocol communication function

With MR-J4-03A6 servo amplifier, driving servo, changing parameters, operating motor function, etc. is
possible using Mitsubishi general-purpose AC servo protocol (RS-422 communication).
In this section, only the configuration of operating RS-422 communication function with MR-J4-03A6 servo
amplifier is described. Refer to chapter 14 for details of the communication specification and protocol, etc.
