• An error occurred in the network communication.
[AL. 086.1_Network communication error 1]
Cause
1.
A network cable has been disconnected.
2.
The wiring of the network cable was incorrect.
3.
A network cable has been disconnected.
4.
Devices on the network (including repeaters
such as hubs) are turned off.
5.
The network was disconnected by an incorrect
procedure.
6.
Data transmission from the controller was
interrupted for a certain time.
7.
The settings of the controller were incorrect.
8.
There is a problem with the surrounding
environment.
9.
The servo amplifier has malfunctioned.
10.
The controller has malfunctioned.
11.
Devices on the network (including repeaters
such as hubs) have malfunctioned.

1.3 Handling methods for alarms/warnings
Check/action method
Check if the network cable is connected correctly.
Turn off the power supply of the servo amplifier, then connect the network
cable correctly.
Check if the connection of network cable is correct.
Check for disconnection in the network cable.
Check that the devices on the network are turned on.
Check if the network was disconnected by a correct procedure for each type of
network.
Refer to "Disconnecting the communication" or "Network disconnection
procedure" in the User's Manual (Communication function).
Check if data transmission from the controller has not been interrupted. If the
data transmission has been interrupted, review the controller communication
setting.
Check the controller settings.
When using CC-Link IE TSN, review communication settings such as those for
increasing the transient transmission time of the controller. Alternatively,
reduce the number of servo amplifiers that enter the network midway.
Check the noise, ambient temperature, and other conditions, and implement
appropriate countermeasures for the cause.
If there is noise, take countermeasures to reduce the noise.
Refer to "Noise reduction techniques" in the following manual.
MR-JET User's Manual (Hardware)
Replace the servo amplifier.
Replace the controller.
Replace the devices on the network.
