Ok, I have a Chinese 3Kw 24,000 RPM water cooled spindle and a Fuler VFD. I changed my machine over to Acorn and I tested my spindle tonight and found out that it was only doing 8,000 RPM. While looking at the VFD, I pushed a couple of buttons and messed it up. I watched a video on how to go in and change parameters and so I went in and tried to set the parameters and did something wrong. Now when it comes on it has a flashing P and 0.0 on the screen. I can't get back into the parameter settings or anything else. The manual that I had found online does not say anything about what that might be. It mainly talks about an E showing an error but no P. I have turned off power from the breaker and restarted but always get the same display.
Anyone have any experience with these and know what this screen is? Possibly how to get back to the Parameter set up screens that I had before or reset the thing back to factory defaults or something? I'm in over my head right now and don't know what to do at this point.
At this point I have no ability to start the spindle either manually or thru Acorn.
It is a Fuler DZB 300 series VFD.
