CNC Machine Controls are somewhat Generic as they can be Adapted to Different Machines by Changing 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 Fanuc! )
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 Controls and Fanuc GN6 Controls Stored this Data in Bubble Memory that also required No Power to hold it for Decades.
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
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 , if you even
Have Strippit & Fanuc Controls Books, Nobody at Your Company Has Ever Read the 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 Photos. It says Change Batteries once a Year and 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, Batteries take over to keep Data Stored.
If you do not change Batteries once every year,
eventually Batteries Wear-Out and
Data will be Lost and Machine will NOT Run.
Typically, Machine Manufactures Supplied Disks,
Tapes, 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 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 them in a Couple of Thumpdrives in
Safe Places! You 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.
