FANUC AC MAIN SPINDLE problem!!

[Cole84]

Hello all.
We have FANUC AC regulator for main spindle type A06B-6059-K0311.
On display we have error message AL-17.
Regulator has display on main board and 4 buttons

MODE UP

DATA_SET DOWN

We have checked all voltages (+24; +15; -15 and 5 V) are they are ok.
Could anybody tell us what is ALARM-17.
How to enter parameters and listing of parameters.

Best regards !

I faced with same problem on the 10T control. But I do not remember model of spindle amp. My control displayed OT113 error and AL-17 was on the spindle amp. I received the quote on the forum:
My notes say Alarm 17:
(1) Meaning
In the main circuit, the voltage at the DC link is abnormally high.
A fuse of the AC reactor unit may have blown.
(2) Cause and troubleshooting
(a) An input fuse of the AC reactor unit has blown.
→ Replace the fuse.
(b) Regeneration circuit failure
→ Replace the unit.

I searched the whole Fanuc Manual for the alarm AL-17.But no luck it was not there.The problem also occured on my machine wich has a Fanuc OT-D control.The problem was tht the serial pulse coder was malfunctioning later when we opened it an IC was blown this defective pulse coder gave wrong signals to the IGBT due to this the IGBT was also found defective. Please check the components of the spindle drive like the IGBT(spindle module).The serial pulse coder(encoder) wich is usually of 1024PPR or 2500PPR,check all its signals.After rectifying some defects in them the problem shud be solved.

I had an AL-17 just this week and this is what I did to fix my problem

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.

Thanks a lot m8 will try that
Nice explanation.

[Cole84]

Now Duke was right i initialize the memory but i didnt get any parameters with machine so i will try to contac machine dealer and try to get parameters. If anybody have parameter or parameters description i would be grateful my machine is anayak-matic-9-cnc.

To my mind type of machine does not very matter. The following text from manual for spindle amp. of Tsugami NP 32. But data for spindle amp. of Tsugami NU4Y are enclosed too.

Only several parameters depend on machine settings. In general, you should look into whole spindle parameters meaning, then find out what kind of model of motor is being used and only then try to change them

[Cole84]

I solved my problem after i got parameters for my machine. The procedure of parameter input was just like DUKE356 told to do only i havent got jumper SET-DRIVE.
Many many thanks to GUHL and DUKE356.
I will post my parameters soon.
