Our shop just acquired a used Fanuc Robodrill Alpha-T142A with the 16i-M control, along with a 5th axis Nikken 5AX-2MT-105-120 that was previously mated with it. We really need help figuring a couple issues out. We got each unit off the truck and plugged them in once in place, and got a couple alarms:
'300 APC ALARM : A AXIS NEED ZRN'
'300 APC ALARM : B AXIS NEED ZRN'
'306 APC ALARM : A AXIS BATTERY ZERO'
'306 APC ALARM : B AXIS BATTERY ZERO'
All I can figure regarding the "battery" alarms is that the APC absolute position coder battery drained while the machine was being shipped, judging by the fact that alarm was gone today after being plugged into the wall and charging overnight. The first two alarms are the real issue; I assume the absolute position was lost when the machines were disconnected from power & batteries drained and the 4th and 5th axis need to be taught zero again although they normally save their position using that battery. How are you supposed to home the darn thing? There is no 'reference point' button for homing on this model robodrill so we tried jogging it manually with the pulse handle and made the problem worse; the A axis stopped moving at one point (seemingly overtravelled, no crunch/clunk sound though) and this alarm came up:
'369 A AXIS: DATA TRANS. ERROR(INT)'
This is the only description I can find for this alarm- "A CRC or stop bit error occurred in the communication data being received from the built-in pulse coder." The machine will no longer let you jog anything with the pulse handle and I can't clear it with the reset button. Is there a hard override on these fanuc's that will let me jog the 5th axis away from the overtravel point so we can hopefully clear the 369 alarm and attempt to home it (once we finally figure out how to do that)?
Couldn't find much relevant material from the manufacturer online but I'll give them a call, any info or ideas you might have would be welcome. Thanks
