Hello Gentlemen.
I’m hoping some one can lay their hands on a Fanuc Alpha servo maintenance manual, and give me the blurb for a # 8 alarm on the Led on that drive.
I’d normally have that manual, but I’m away in the bush about 4 hours from town. Here doing some thing else and got roped into this as well.
I have a Deawoo Puma 250 Lathe 1998 , Fanuc OT-C control, A06B-6079-H106 Single axis Alpha Servo module.
As soon as the control comes up, I get a “424 Servo Alarm - Z axis Detect error” and a 401 “Servo Alarm (Vrdy Off)”. I’m convinced the 424 is the real alarm, as the 401 clears with reset. The 424 is solid.
When I read the alarm code on the drive module its self, it is showing a # 8. Can any one reach for a manual and give me the definition of that? This comes up virtually instantly I push the machine ready button. And stays there.
I’m thinking its to do with the drives its self. I’ve checked and cleaned the encoder feed back side. That’s all spotless. I get different alarms when I leave those disconnected.
The Number 8 alarm even stays there with the motor connections disconnected from the bottom of the drive. I’ve got no chance of swapping motors or servo modules, as the X and Z are different.
Input voltage is good, DC bus voltage is in spec, 24 volts is good, both fuses on the module are fine. I’ve had the drive out and pulled the covers. It all looks clean, nothing obvious blown. Transistors look O.K
I believe that maintenance manual is B-65162. Can I please get a explanation of what a #8 alarm is?
If anyone happened to have that in PDF, that would be even better.
Best regards
Phil.
