hey everyone,

im having a huge issues with my shopbot PRS Alpha, the damn thing has problems the faults code:EF4 I believe, which indicates that there is some mysterious issue in the spindle. Sooo... to date i have checked all connections from VFD to spindle and spindle to board all is AOK. Spindle does not seem to overheating issues.

can someone give me some insight, I have been on the horn with tech support but have been unable to resolve the issue.

the system is PRS alpha: auto tool changer upgrade from shopbot. Ill find all the part number etc.. this afternoon when im in front of my machine.

thanks

Don't know if this will help, but...

From Yaskawa manual:


EF4: External fault input
Protective command from control
Operation. circuit terminal S4

S4 Multi-Function-Input 4 Factory setting is " Fault Reset " (1)

Do you have the manual that came with it? Pretty good documentation.

Hope this helps!
