Acorn / Leadshine "9031 DRIVE FAULT"

[Richard70]

Just wondering, since flipping the step and direction switches in Wizard advanced axis helped to make my problem go away,
would flipping the enable switches do the same for the enable input?

[Nick4Maker]

No effect on flipping direction in Wizard. I will try again.

"Correction"
When I 1st read your suggestions, it was on my phone, while I was coaching a Basketball game. I only tried switching step & direction. See below for my results.

Same issues with me (drive faults & 5VDC boot up), except I have DMM motors & DYN4 drives.
Thanks to all the contributors, I almost had it figured out, but unable to move motors with ENA wire connection (DYN4 PIN15 to Acorn H2,3 ENA), in Acorn CNC12. Without ENA connected, all motors move and test G-code shows motor movement.

Therefore, since the problems are the same (except diff. motors), should I post my set-up, trials and results here?
Or should I start a new thread?

Thanks to all,

Nick

You should start your own thread. DYN4 drives and Leadshine in this thread is not the same.
Search DRAFT DYN4 and did you use that schematic by the way?

[Nick4Maker]

Ok, I will search for Draft DYN4 schematic.
Then start new thread.

Thx, Nick

Ok, good news, found the issue. Thanks Richard, that worked.
In the Wizard, under the "Advanced Axis Configuration" tab, I simply checked off "Enable" to "X" drive and it worked. Powered down and made the changed to the "Y" & "Z". Tested again and still works, what a relief after days of frustration or some call it fun .

Here is a quick summary for other people:

Hardware Configuration:
- Acorn Rev.3
- DMM DYN4 (w/latest version, which includes fix for noise when using a spindle motor & ZRI added feature), DMM tech were nice enough to do an exchange, since my drive were recently purchased.
- Followed Acorn_DYN4_draft.pdf for wire schematics (link:download/file.php?id=1567)
- Also used the following DMM-Tech updated schematics:
DYN4 to Acorn Connection Diagram: http://dmm-tech.com/Files/schematics/...
DYN4 to Acorn Servo Spindle Connection Diagram: http://dmm-tech.com/Files/schematics/...

Problems:
1) "9031 Drive Fault" when in CNC12 and attempting homing or motor movement (Bench test in DMM program worked fine)
2) Acorn not able to boot, only +24V LED would light up
3) Narrowed down drives not able to move due to ENA wire connection (DYN4 PIN15 to Acorn H2,3 ENA)

Solutions
1) In Wizard under Tab 1. "Primary System Configuration", changed Input 5 channel to NO from NC (does not seem right, but it works )
2) Wired the panel circuit where main disconnect gives power to Acorn, HW E-stop & Door Motor Run enable switch. Then the Enable Switch turns on the breakers for all the motors drives & the +5VDC. This allows me to sequence power to Acorn 1st, then turn on all other components, specifically 5VDC for the PUL+(Pin 11)/Dir+(Pin 10).
3) As listed above, in the Wizard, under the "Advanced Axis Configuration" tab, I simply checked off "Enable" for X,Y & Z.

Many thanks to all, especially Richard and his headaches & as always Marty. Someone should start a go fund me page for Marty, he has helped out so many people.

Well on to other challenges, need to configure spindle motor with encoder & resolve my "Z" motor, which has a brake and I'm having temp issues (motor & brake fighting each other). This will be a new thread.

Thanks,
Nick

No problem. It's why we are here.
As for the brake, it needs to release when the drive is enabled.
Double check with DMM, I believe they have a built in method to release it as needed. Though I'm not for sure.

Z axis with linear guide rails and ballscrews usually need a brake to keep the head from falling when servo is not enabled and holding the axis.

I just have to give a huge thanks for this thread, solved my 8082 not moving issue in about 10 min after spending hours troubleshooting! You guys rock!

That why the board is here. Hopefully folks will take the time to use the search feature with some key words to find what they are looking for. Glad it helped you.
