[Al. 02A_Linear Encoder Error 1] - Mitsubishi Electric MR-J5-G Series User Manual

[AL. 02A_Linear encoder error 1]

• An error of the linear encoder was detected. The content of the errors varies depending on each encoder manufacturer.
[AL. 02A.1_Linear encoder error 1-1]
Cause
1.
There is a problem with the way that the linear
encoder and the head are mounted.
2.
The external conductor of the encoder cable is
not connected to the ground plate of the
connector.
3.
There is a problem with the surrounding
environment.
4.
A linear encoder alarm was detected.

1.3 Handling methods for alarms/warnings
Check/action method
Adjust the positions of the linear encoder and the head.
Check if the external conductor of the encoder cable is connected to the
ground plate of the connector.
Refer to "Shield procedure of CN2, CN2A, CN2B, and CN2C side connectors"
in the following manual.
Rotary Servo Motor User's Manual (HK series)
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.
