[AL. 070.6_Load-side encoder initial communication - Transmission data error 2]
Cause
1.
If an A/B/Z-phase differential output type
encoder is being used, the wiring of the
encoder is incorrect.
2.
There is a problem with the load-side encoder
cable.
3.
The servo amplifier has malfunctioned.
4.
The load-side encoder has malfunctioned.
5.
There is a problem with the surrounding
environment.

1.3 Handling methods for alarms/warnings
Check/action method
Check if the Z-phase pulse signals (PZ and PZR) of the encoder cable have
been disconnected or have shorted.
Refer to "A/B/Z-phase differential output type encoder" in the following manual.

Page 78 [AL. 070.1_Load-side encoder initial communication - Receive
data error 1]
Check/action method
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.
