18. MR-J4-03A6 SERVO AMPLIFIER
18 - 82
18.9 Mitsubishi general-purpose AC servo protocol communication function
POINT
The USB communication function and RS-422 communication function are
mutually exclusive. They cannot be used together.
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.
