Error 327 on Rapid (Z Axis Move)

[Chaz]

New error for me, not had this before.

I'm getting an Error 327 - same place each time when trying to cut a part. I dont have the code, but ive slowed down the Axis. Ill get the code across in a bit but Report attached.

From other errors it sounds like a noise issue but not had issues before, suggestions welcome.

Thanks

Make sure you are using shielded ethernet cables. Make sure PC, ethernet cable are seated very well and routed away from anything that can cause EMI

Thanks, its using the supplied Ethernet cable and is as it was before the problem started. I did install a small VFD however to run the coolant pump but its in its own box with the Spindle VFD. Ill disconnect it and see if the problem goes away.

[martyscncgarage]

Might be the coolant pump vfd.
I'll be interested to know what you find

[Chaz]

Indeed. The VFD wasnt running at the time but its connected and powered.

[Chaz]

Ok, tested again.

VFD disconnected, no problems.

VFD connected, not running, same issue.

The VFD is power from the same powersource in a cabinet adjacent to where the Acorn controller is. The only wiring going to it from Acorn is an unshielded 3 core cable, using 2 cores to switch on the VFD to run the coolant pump.

From the VFD it goes to the motor via a route nowhere near the Acorn setup.

What's interesting is that it shows:-

9031 DRIVE FAULT!
327 Fault

Yet there is no fault wiring going to the HSS86 drives, so how / why does Acorn think there is a drive fault?

New report attached.

The MPU REquest resend is bad ethernet packet data. Likely from NOISE.
Open your diagnostic screen (Alt+i) look at your Drive Fault input, what state is it?

I think you have a nasty VFD...

What is "3 core cable"?

I would use the digital inputs on the VFD to turn your pump on and off, not power up and down the VFD if that's what you are doing....

Thanks, saw those messages in the logs too. I dont believe I have anything connected to the input for drive fault. Need to check, the machine was retrofitted by another forum member here. Ive got some screenshots (Ive closed up the garage for now), so wont head back in tonight.
