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 !
