Help me please,
My CNC is Fanuc 18M router machine.
When i turn on power. The machine has an error 414 SERVO ALARM. X,Y,Z axis detect error. I think that is lower DC voltage.
I see the led on main power is 02
00 is ready
-- is not ready
## is number code
Can you help me? How is the 02 code?
I just check 24V DC power. I changed a new cooling fan. Number 02 alarm code become --. but on screen has a message "401 X,Y,Z,V,A SERVO VDF DETECT ERROR"
"2" low voltage
if your drive is A06B-6066-Hxxx check circuit breaker inside the drive and of course all power connections (R, S, T)
if incoming voltage is OK, then it's needed to check PCB inside the drive
the DC wires are too thick to be bad, besides you may measure DC voltage on incoming terminals L+ L-
step 1: measure DC voltage. is it OK?
no -> the fault is searched, think what to do further
yes -> go to step 2
step 2: swap control cables between axes. the fault moves to another axis?
yes -> the drive or motor is faulty. think what to do further
no -> the problem is not in drive. think what to do further
tell what type of axis control card is being used?
