[Al. 070_Load-Side Encoder Initial Communication Error 1] - Mitsubishi Electric MR-J5-G Series User Manual

[AL. 070_Load-side encoder initial communication error 1]

• There is a communication error between the load-side encoder and servo amplifier.
[AL. 070.1_Load-side encoder initial communication - Receive data error 1]
Cause
1.
There is a problem with the load-side encoder
cable.
2.
If an A/B/Z-phase differential output type
encoder is being used, the servo amplifier is
not compatible with the A/B/Z-phase
differential output type encoder.
3.
If an A/B/Z-phase differential output type
encoder is being used, the connection with the
encoder is incorrect.
4.
The servo amplifier has malfunctioned.
5.
The load-side encoder has malfunctioned.
6.
There is a problem with the surrounding
environment.

1.3 Handling methods for alarms/warnings
Check/action method
Check if the load-side encoder cable has been disconnected, incorrectly wired,
or has shorted.
If there is a problem with the cable, replace or repair the cable.
Check if the servo amplifier is compatible with the A/B/Z-phase differential
output type encoder.
Refer to "Compatible linear encoder list" in the following manual.
MR-J5 Partner's Encoder User's Manual
Check if the wiring of the A/B/Z-phase differential output type encoder is
correct. Check if the encoder is wired to PSEL.
Refer to "A/B/Z-phase differential output type encoder" in the following manual.
MR-J5 Partner's Encoder User's Manual
Replace the servo amplifier.
Replace the load-side encoder.
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.
