[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.
Mounting condition of the linear encoder and
head is failure.
2.
The external conductor of the encoder cable is
not connected to the ground plate of the
connector.
3.
There is an abnormality in 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 head.
Check if the external conductor of the encoder cable is connected to the
ground plate of the connector.
Refer to "Ground plate connection" in the following manual.
Rotary Servo Motor User's Manual (HK series)
Check the noise, ambient temperature, and others, 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.
