I have a Hitachi Seiki HC 400 with a Fanuc 15-m control. The machine was left off for an extended period of time. Upon start up it had an A axis servo alarm and overtravel of every axis in positive and negative. The machine doesn't even have an A axis. I turned off the axis in parametes and that alarm cleared but others will not clear. I found that the batteries had died and started to leak. I replaced the batteries and was able to locate a copy of all my parameters. I reloaded parameters and same overtravel alarms will not clear. I have had Fanuc service in on this and was told they could not help without wiring diagrams which we do not have. I am not getting anywhere with Mori support and I am really banging my head on this one. Please help!
Thanks
