Software Policy: We do not sell or distribute Fadal copyrighted software. Boards such as the 1400 CPU board and the 1010 Axis controller board requires Fadal copyrighted software. It is best to retain and use your original Eproms and avoid introducing software compatibility issues. Contact a Fadal authorized Eprom supplier, they provide Eprom upgrade exchanges, usually for free.


About the Main CPU Boards:
Throughout the history of producing machines, there have been 6 main cpu boards.  Each identified by a dash number.  The very first machine (VMC45) used the 1400-1 board as well as the first VMC40s.  The 1400-2 was the second generation control board and each new revision was added as new INTEL microprocessors became available.

The 1400 board is the Central Processing Unit of the CNC control. All CPU boards come with 38K of battery backed memory. This memory is used to store the following:
   • CNC Part Program
   • Tool Data – both Length and Diameter
   • Fixture Offset Data
   • SETP parameters
   • Backlash
The CPU board executes the part program by issuing commands to the other boards and monitors the inputs from the other boards and proceeds as required by program and external information.

The Fadal CPUs are as follows:
  • 1400-1 – This was the first CPU, it is very rare, if you have problems with one please call for assistance.

  • 1400-2 – Served many years as the CPU. Can be in any of the first 5 slots however try to keep them in slot 5. Has a Program Module (1610-0) plugged into it, this module provides the operating code for the CPU. For optional memory expansion, memory expansion boards (1460-1) were added in slots 1 to 4. Each board contained 128K. Up to three memory boards could be added for a total of 422K.

  • 1400-3 – This CPU board was an interim CPU between the 1400-2 and the 1400-4. It has to be in slot 5 because of the bus board which connects the Computer Interface Board and the CPU. This CPU uses the Computer Interface for the video signal. This CPU uses the Program Module (1610-1) and the Expanded Memory Boards that plug into the CPU Board. (J4-J5) Up to 422K Expanded Memory total.

 • 1400-4 – This CPU board was used for years. It has to be in slot 5 because of the processor bus board which connects the Computer Interface Board (1030), the Video Graphics Board (1420-4) and the CPU. This CPU uses the Video Graphics for the video signal and the graphics. This CPU uses the Program Module (1610-1) and the Expanded Memory Boards that plug into the CPU Board. (J4-J5) Up to 422K Expanded Memory total.

 • 1400-5 - This CPU board is the current CPU. It has to be in slot 5 because of the processor bus board which connects the Computer Interface Board (1030), the Video Graphics Board (1420) and the CPU. This CPU uses the Video Graphics for the video signal and the graphics. This CPU uses the Program Module (1610-1) and the Expanded Memory Boards that plug into the CPU Board. (J4-J5) Up to 16MB Expanded Memory total.



True Knowledge and Experience you can Trust:

Experience - Always Your Best Choice:
Having been involved in the original design and production of the Fadal CNC hardware and software, we truly understand these boards; to the component level and the requirements for properly repairing and testing of all the boards we offer. With over 18 years of production testing and repairing Fadals CNC boards, there is none better experienced or equipped than ITS.
Independent Technology Service Inc. (ITS), the original PCB board house for Fadal, has been testing and repairing all production boards, since 1991.

 On your board, chances are you'll see the stamp already on it!

Before You Buy - Ask how the board was tested!
One simple question can save you a lot of frustration, wasted time and money when servicing a problematic machine. The common "repair" method today for others selling boards is to put a used board in a machine and see if it fails. It cannot be considered a "good board" just because the control doesn't fault. Most of the time there is no history of the board, no record of past performance (problems).
In fact, without proper testing, chances are you will be getting other unknown board problems when installing used, untested boards; wasting even more of your time and money!

Testing That Is Unsurpassed!
We are the only ones who can properly test and repair CNC88 boards!  It requires component level testing to verify that each and every component is performing to original specifications.

The Best And Only Way - In Circuit and Functional Testing:
The testing of electric circuits to determine and locate any of the following circuit conditions:
  (1) an open circuit.
  (2) a short circuit with another conductor in the same circuit.
  (3) a ground, which is a short circuit between a conductor and ground.
  (4) leakage (a high-resistance path across a portion of the circuit, to another circuit, or to ground).
  (5) a cross (a short circuit or leakage between conductors of different circuits).
  (6) a marginal or failed component(s).





The simple fact is that proper circuit testing for complex systems requires extensive automatic testing equipment to determine the failures defined above as well as many other quantities required to insure the board is working correctly.

CNC Board Replacement Options:
 1- New or Remanufactured exchanges are available for immediate shipping, requires core exchange.  A core refund is issued when we receive the bad pcb board.  The core return board must be in a state that is repairable not damaged.

 2- We will repair your board, for about 1/2 the cost of exchange replacement!  Rush repairs are available on most boards.
