fanuc OM high voltage alarm

[maxvic]

I've got a Fanuc OM controller and I keep getting error codes 401 and 414 (Velocity ready off, and X axis detect servo error) 414 error code leads to diagnostic 720 which reads 00010000 and Fanuc has told me that this is a high voltage condition. I have since purcased a new phase converter that is putting out 238,238,237 volts over all combos - still the alarm. So I go back to Fanuc and they say it must be my servo board so I buy a new one - still the alarm. I am out of money and out of time trying to fix this thing, if anyone has any ideas I would love to hear them.

Thanks, Maxvic

I just run them (and break them) call service in I hate to take my car to the shop but what can you do

[maxvic]

I've already had Boston Machine up to fix it and they pretty much just shrugged and said try a new phase converter - which I did.

boston machine is good for sales you might give methiods a call they ih the area and handle sales and service for Matsuura wich use that controller

Thanks, I wasn't sure if they would work on my machine because it is a Dahlih but I'll give them a try.

Thanks,

That bit indicates high current, does it fault out immediatly? or when loaded or in rapid?
Try running with the motor removed from the load, also try swopping motors if they are the same size.

I have to take care of a Dahlih too. Is that axis counterbalanced by a hydraulic piston? Maybe the valve gets stuck, it happened to me once.

Not sure if it would have caused an error or not, but...
I still think it was a bit over cautious, but we just had Puma lathe /w Fanuc installed and the line voltage was around 230 and they refused to set it up untill we installed transformers to step it down between 208-220. It was claimed it could damage it and of course the seller would not honor warrenty if the voltage was not to spec. So $1300 later, it is running. For $200k+ you would think they could include a built in transformer to make it run on standard supplies for the country it is sold in.

hello maxvic
i think ur voltag converter is producing high volts
according to fanuc system
so just re adjust the voltage in between 200 to 220 volts and after it reset ur alarms
Cheers.

This one could actually be a simple fix.....You will get these alarms if the amplifier in question has a cooling fan, and the fan has stopped working. Not all amplifiers have fans, but it would pay to check this before you go to too much trouble.

Thanks, I will check and let you know,

Its the X axis alarm but it is driven by a ballscrew with no counterbalance.

Thanks though,
