Got my new EX controller with servo’s, so I spent the weekend taking things apart and hooking everything back together.
Generally the physical work went well, but after the upgrade I get the same “9031” spindle fault error when trying to jog that others have reported.
I have filed some details with support and hope to hear from them tomorrow.
I thought I would include what I have tried so far here and report resolution in case other folks run into this as well.
I have double checked the following:
All cables are connected. Especially I checked the brake cable is connected.
The VFD parameters have been updated as detailed in the instructions.
The configuration wizard has been run and the servo settings have been selected.
Only the A axis lights up red on the plug in panel when I power up. All the other axes are showing no lights.
When I jog any axis it moves a small amount in the requested direction, then faults.
When I jog the Z axis, it falls, then jogs and faults. It seems the brake is released, and then the motor jogs in the requested direction after a delay.
I did check and I can manually start and stop the spindle using the MPG.
I have not messed with the sensor setups yet, but I can’t get the system to jog in the middle of the range, so not sure how that would make any difference.
Hopefully turns out to be something easy to fix once we get support in the loop, but I think I have checked the reported potential problems that I have seen here so far.
Seems that many of us are dealing with the same issues. Last night I went through and checked all cables again. The z axis seemed to be the one giving me issues. I reseated that motor cable again and out of nowhere I was able to home and do the tool setter utility so I thought I was in the clear. Then I tried to add in the spindle to the mix and then the faults reappeared.
Wait for avid support - but it may be this: On the board inside the control box that connects to the outputs, there are sets of 3 pins with jumpers spanning between two of them. They told me to move the jumper connected to the A-axis to the other orientation, spanning the middle pin and the previously un-jumped pin.
Good news, I had a bit of an exchange with support, and when none of the obvious things to check seemed to be a problem, I pulled off the 14 pin VFD cable and checked the pins for continuity. Both pins 1 and 2 which form the circuit that is normally closed when there is no fault failed. When I opened up the connectors I found loose wires on both ends. Both pins 1 and 2 where disonnected on one end, and on the other end pin 1 was disconnected.
I got the circuit closed by pushing the wires back into place and carefully reassembling the connectors with the strain relief having a bit of extra slack.
This is not a real repair, but it did get me into a state where I can home the machine and jog succesfully.
I don’t have time to dig into callibration and such today, maybe later this week.
In the meantime I’ve asked support about sourcing a new 14 pin cable, since I don’t have the right gear to really fix the disconnected pins in the cable I have.
So, if you are getting a VFD fault, consider that the cable might be broken!
