CNC Machine Controls are somewhat Generic as they can be Adapted to Different Machines by Changing the Stored Parameters & Macro Programs that tell Control how to run a Particular Machine.
This Special Parameter & Macro Program Information is Custom Written by the
Manufacture of Your Machine Tool
( Not the Control Manufacturer! )
Specificity for each Model Machine Tool.
If this Control Information is Ever Lost , Your Machine Will Not Run Until it is Correctly Replaced!
In Early Strippit HECC80/1 Type Controls this Information was in Non-Volatile EPROM Memory that could Store it Correctly for Decades even with No Power to Control & Machine. Later Strippit HECC80/3 Type Controls and Fanuc GN6 Controls Stored this Data in Bubble Memory that also required No Power to hold it for Decades.
The Fanuc OP Control was used by Strippit, Amada,
and other CNC Machine Tool Companies in Late 1980's and 1990's. The OP is a Good Control, but
it Stores Critical Parameters & Macro Programs in Volatile, but Battery Backed-Up RAM Memory.
Strippit & Fanuc Poorly Document the Fact that You are Suppose to put New Batteries in Control Every Year. And let's be Honest Here, if you even Have the Strippit & Fanuc Controls Books, Nobody at your Company has Ever Read Books anyway.
So, Sit Down on Floor and Read the Hard-To-Read Printing Molded into Black-Cover in Lower Left Side of your Control, Like Control in the Photos. It says Change Batteries once a Year and to be sure
Control Power is On when Replacing Batteries.
When Control is On, Power is Supplied to RAM Memory to keep Data Stored. When Control Power is Off, the Batteries take over to keep Data Stored. But if you do not change Batteries once every year, eventually Batteries Wear-Out and your Data will be Lost and Machine will Not Run.
Typically, Machine Manufactures Supplied Disks or Printed Copies of Data so a Good Technician could Reload Lost Control Data. But you Probably Lost Data when you Lost Manuals. If you do not have Data Copies and if the Machine Company has Gone Out Of Business or Can't Supply Correct Data,
your Machine Tool is now Scrap Metal.
Typical Symptoms are 100 and 101 Alarm Error Code Messages on Control CRT Display. There is Sometimes a "Low Battery" Message on Display.
So, before this Happens, I Advice;
1 -- Change The Control Batteries!!!
2 -- Download Copies of ALL Parameters and Macro
Programs to a PC Computer and Store in
Safe Places. You may need an Experienced
Fanuc Control Technician to get All Data!!!
To Change Batteries;
1 -- Turn-On Control
2 -- Leave The Control On!!!
3 -- Remove the Black Battery Cover.
4 -- Remove the 3 "D" Batteries.
5 -- If Battery Holder Contacts are Dirty or
Corroded, Clean with a Scotch-Bright Pad.
6 -- Put in 3 New Alkaline Batteries.
Do Not use Rechargeable Type Batteries!
7 -- Make sure you Orient Batteries in Correct
Direction, so that Plus & Minus are Correct!
8 -- Replace Cover.
9 -- Tape a Paper-Log to Control showing Date
Batteries were changed so you know when to
change them again, like this Customer taped
on Front Right of their Control.
