I just upgraded my Avid 4896 motors with a new EX controller. I followed the instructions for updating my VFD (Mitsubishi D700) but whenever I try to start the spindle I get a 9031 error message. I first attempted sending a file from Fusion and then attempted a spindle warm up.
I’ve checked and rechecked the cables, reset the machine using the e-stop, and turned the machine/centroid on and off more times than I can count. Anyone have any ideas where to look to figure out what’s going wrong?
Can you test the vfd and spindle if it is disconnected from the system?
How would you recommend I go about doing that?
I looked further into it - super helpful suggestion! I attempted to run the D700 a few times and I got two error messages (e.oht and eoc1). Not sure what could be causing either. The spindle was working perfectly before I swapped out the motors
If you want to get up and running you can just bypass the VFD fault by flipping a dip switch on the servo board: Schematics - EX Controller Technical Manual
That board is where all of the 8 pin connectors for your servo motors connect to the control box.
E.OC1, E.OC2, E.OC3: Overcurrent Trip. Occurs during acceleration (OC1), constant speed (OC2), or deceleration/stop (OC3). Check for short circuits, heavy loads, or insufficient acceleration/deceleration times.
First I would check that I updated the VFD correctly. Then I would check the wires for opens/shorts with an ohm meter. Then I would reset the vfd programming and try again.
Good point, a common failure is not tightening down those M23 cables (spindle power cables)
They are easy to cross thread and not seat properly
