Hi
Periodically when I power on the machine I get AL-17 on A06B-6055-H108 spindle unit with A20B-1001-0120 main board.
Earlier I have been advised possible reasons:
(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.
But nothing of this doesn't attend.
May bad capacitors cause this alarm?
