Help! I just purchased a dainichi f 15 lathe with a fanuc series 21 TB control. The machine is like brand new with only 24 run hours (came out of a college).
I powered it up and got a servo turret alarm (2048). The fanuc beta series pulse coder had weak batteries. I replaced the batteries but still have the alarm. The led on the pulse coder is flashing 11U. I belive the turret has lost its reference position because the screen shows tool number T00. The manual says to exacute a dogless reference position setting to memorize reference position. How do I do this as I am unfamiliar with this control? Any help would ne appreciated. Thanks, Norb![]()
Thanks for the help but I contacted Dainichi and they sent me the instructions. I had to change a bit on a keep relay then index the turret to tool 1, change the bit back to the original setting and power down then back up again, I hope this info can be of help to others. The Dainichi people were very friendly and helpful especially Harris. Thanks to all, Norb
