Ac Fanuc spindle alarm AL-17

How to initialize the memory (NV-RAM) on the AC Digital Spindle PCB. 
ALARM #17

1) Obtain a current spindle parameter list from the Machine Tool Builder.
(This parameter list was supplied by the MTB and should be with the machine.)

2) Turn main power off.

3) On the spindle board change the jumper setting “S1” from DRIVE to TEST.

4) On newer spindle PCB, “SH” jumper must be set from DRIVE to SET.
(Most spindle boards do not have this jumper setting.)

5) Turn the main power on.
You will see the 7 segment display changing as follows.
(00000) to (11111) to…to (FFFFF) to (00000) etc.

6) Push and hold down all 4 buttons (MODE, DATA SET, UP & DOWN)
at the same time until you see (FFFFF) on the display.

7) Push and hold down the (MODE) button, while pushing the (UP) or (DOWN)
button until (FC-22) is displayed.

8) Push and hold the (DATA SET) button until you see (GOOD) on the display.

9) Turn the main power off.

10) Change the “S1” jumper setting from TEST to DRIVE.

11) Change the “SN” jumper setting from SET to DRIVE. (If board has jumper)

At this point, the generic spindle parameters are set. Your machine will not operate properly with these parameters.
The next step is to load the customized parameters back into your machine. The MTB parameter list is needed at this time.

HOW TO CHANGE PARAMETERS

1) With the main power off, set the “SH” jumper from DRIVE to SET
(Most spindle boards do not have this jumper setting.)

2) Turn the main power on.

3) Push and hold all 4 buttons (MODE, DATA SET, UP & DOWN)
at the same time until you see (FFFFF) on the display.

4) Push the (MODE) button, you will see parameter number (F-00) Release the(MODE) button to see the parameter contents.

5) To change the parameter number, push and hold down the (MODE) button, and push the (UP) or (DOWN) buttons to scroll to the next parameter.

6) To change contents of parameter, release the (MODE) button and push the (UP) or (DOWN) button. Change the value to the values on the parameter sheet.

7) After all parameters have been changed, push and hold the (DATA SET) button untill you see (88888) on the display

8) Turn the main power off.

9) Change the “SH” jumper setting from SET to DRIVE. (if jumper is used)

The spindle board has been initalized and the parameters reset. At this time your spindle should run
