ALARM AL-11 on Fanuc A06B-6059-H206#H550

[Housica]

Hello guys ,

I have a fanuc spindle drive A06B-6059-H206#H550 and when starting it AL-11 goes out.
I changed the transistor modules with new ones but the alarm continues to appear, i check the input power voltaje its ok 210 VAC
Some ideas on how to solve the problem ???.

the alarm is related to the DC link output power that is too high,there is no related to transistors.
the problem is in your power PCB of that spindle drive

not to overlook the obvious but next to the voltage selector switch (220/200) on this unit is F5 and F6. One or both may be open. Remove from ckt - with power off - and check.
