Startup; Modbus/Tcp Initial Communication Setting - Mitsubishi Electric MR-JE-C Series Instruction Manual

3. Modbus/TCP

3.7 Startup

This chapter describes the network setting of the MR-JE-_C servo amplifier. Refer to "MR-JE-_C Servo
Amplifier Instruction Manual", "MR-JE-_C Servo Amplifier Instruction Manual (Profile Mode)", and "MR-JE-_
C Servo Amplifier Instruction Manual (Positioning Mode)" for other startup settings.

3.7.1 Modbus/TCP initial communication setting

Make the initial communication settings in the following procedure.
Communication function
selection setting
IP address setting
Subnet mask setting
Default gateway setting
Server (servo amplifier)
power cycling
Client (controller)
Modbus/TCP communication start
POINT
When using Modbus/TCP communication, set [Pr. PN10 Ethernet
communication time-out selection] before driving the servo motor. The servo
motor may continue to operate after the communication is disabled due to a
communication shut-off or other causes.
Setting [Pr. PN10 Ethernet communication time-out selection] to a small value
may trigger [AL. 86.4] in the following condition: the power of the servo amplifier
is cycled, or an instantaneous power failure occurs during Modbus/TCP
communication.
[Communication function selection setting]
The initial setting is Ethernet communication. If RS-485 communication is set, change to
Ethernet communication with the following parameter. (Refer to chapter 5.)
Parameter ("communication function selection" of [Pr. PN08 Function selection N-2])
[IP address setting]
The initial value is 192.168.3.0. To change the initial value, set it with either of the
following (1) or (2). (Refer to section 3.7.2.)
(1) Identification number setting rotary switch (SW1/SW2)
(2) Parameter ([Pr. PN11] to [Pr. PN14])
[Subnet mask setting]
The initial value is 255.255.255.0. Set it with the parameters ([Pr. PN15] to [Pr. PN18]).
(Refer to chapter 5.)
[Default gateway setting]
The initial value is 192.168.3.1. Set it with the parameters ([Pr. PN19] to [Pr. PN22]).
(Refer to chapter 5.)
[Server (servo amplifier) power cycling]
The settings of the IP address, subnet mask, and default gateway are reflected.
[Modbus/TCP communication start]
Start Modbus/TCP communication of the client (controller).
