    Any idea what would cause the parameters to not save on a A500?

    Peepaw, did you get into an altercation with a wild rabid set of clippers?? What happened there? At least hair always grows back :)

      If it comes up in Japanese every time, is there also a problem with the battery (or the eeprom)??

      Hello Sir, I am so sorry. I have no knowledge of the 1320. The only ACOPOS that I have ever worked on, was the 1080 in the video I made. In the future, I will continue to look out for this servo drive. Possibly someone that has an answer to your 1320 malfunction can leave a comment on how they repaired their drive.

      @@cherifelmilegh9757 Malfunction: Does not run the feeder motor. Just on the chance I don't get to part 2 and Part 3. I found what appears to be a circuit breaker that was tripped on the drive. it is located next to the place where the red and black fuse wires connect to the board. On the circuit breaker is a blue switch. I flipped the switch to the opposite direction that it was set. And then I measured good voltage diode drops from +Bus to U, V, and W. I hope this helps in your repair :)
