Hi every body,
please help me !
I have one Hurco BMC 30 whith Fanuc Drivers. When power on the spindle driver appear : AL 17..
Could you help me with the meaning AL 17? Or better or better with significance and other alarms signs . Where to find them , because Fanuc is very very hermetic . Can a user manual anyone help me to download it? .
My driver is the type AO6B -655 - H122
Thank you

Hello

Error seems to be related to NVRAM on Spindle PCB

To initialize the NVRAM:

1. Power down.
2. Move shorting pin (S1) to TEST position.
3. Power on.
4. Hold all four switches until FFFFF is displayed.
5. Hold the MODE button and press the UP button until FC-22 is displayed.
6. Hold the DATA SET button until GOOD is displayed.
7. Power down.
8. Move shorting pin back to normal position.
9. Power on.

This procedure is necessary when the NVRAM has been replaced or when alarm 17 or 23 has occurred. Anytime you have an alarm which will not go away, you can try this. Alarm AL-23 must be cleared this way, it will not go away by cycling power.

As far as I know, there is no procedure to backup except manual recording
