I have a Leblond/Makino FNC-106 with a Fanuc OM control. We have been getting a lube error on the console & fault light. Once the fault light comes on you can't clear it with a reset, or drip feed a program or type a program in from the console. The machine is getting plenty of way oil. There is what looks like a pressure sensor on the Showa lube system, but I don't know how to check it. The lube pump is functioning ok, the hydraulic reservoir is full & has 550 psi & the spindle chiller works & the site buble has oil circulating.

This error has been coming & going for a few months now. The machine will run for about 15 minutes without an alarm. The only way I can find to reset the error so that I can drip feed is to completely power down.

I've got a job on the table that has to get out.

Can anybody tell me how to reset the error so that we can execute commands or have a possible solution to the fault light?

Thanks,

Mike
