I'm hoping one of you guys can help me out. We just threw the 4th axis back on the machine and as usual we're running into a bunch of problems. What I've done so far, pulled the dummy plug, hooked up the 4th axis. Changed the parameters to XYZA, then powered down and up. At this point it was just giving an A axis fault, sometimes, error #1, sometimes error #18, zeroed the memory as this worked last time. Checked all of the fuses and breakers, fine, lights are on on all of the boards. Diagnostics says all the boards are fine, yet still the 4th axis wouldn't work or even move. Then it started throwing axis faults on the X Y and Z. This was friday so we said screw it, went out and got drunk.
Fast forward to this morning. Fired it up. skipped the CS and went to jog, the X Y and Z are running fine, flip over to A and get an axis fault. So I decided to try cold starting it and the X Y and Z did their little dance and the A did a full 360. Then It gave me a Z axis and A axis fault. Hit jog, and the A moved a little and the screen went blank. Shut it down and power it back up and hit jog and the A moves about 5 degrees and throws me "A axis fauly error #1 motor overload, reset emergency stop condition". Thats all its doing now. I'm getting annoyed with this thing and hopefully someone has run across this before.
The 4th axis a vh65, and as far as I can tell the machine isn't set up to use the break, and the line isn't hooked up anyway. When the A is moving it doesn't sound like its working against anything, so I'm at a loss.
