I had a power outage which was accompanied by a power surge which caused the title alarm. I have 2 identical Citizen L20s, however on the other L20 the power issue tripped the inside breakers, once reset the machine came back up and work normally. However on this other L20 the breaker never tripped and now I'm left with the title fault. It is a mitsubishi equipped machine so any citizen documentation that I have is completely useless. Citizen has been informed of the issue and they are suggesting the the Y1 servo need replaced. I'm not completely convinced and was curious about any troubleshoot methods before I purchase a new servo motor.
