Spindle fault reset

Post by xr4x4ti »

Dumb question, but how do you reset a spindle fault in CNC12 mill?

I am still debugging my Protrak conversion with the allin1DC and a few times I have forgot to plug in the VFD. This results in a spindle fault. I will then plug in the VFD and the input chances state, but no matter what I do I cannot get the machine to jog.

I thought you just had to reset the machine once the fault has been cleared, but that does not seem to work.

Am I doing something wrong?

If I cycle power, then the machine works normally.

Thanks,
Tim

Pressing and releasing the emergency stop button should clear the fault condition.

Whether cycling the "reset" button on the VCP does, depends on the particular PLC program you are using.

Here is an Allin1DC basic mill PLC program, with CWP/WMPG and VCP/VCP2 support, that will correctly reset a spindle fault with either Emergency Stop or the VCP Reset button.

Thanks for the quick reply.

In my case pressing and releasing the e-stop or the VCP reset did not clear the fault.

Here is my report.
Am I using the correct PLC?

Thanks,
Tim

Do you have the fault reset line connected to your VFD? If not you'll need to manually clear the fault on the VFD.

If you wired the machine, what schematic number did you follow and what VFD do you have? (Make and Model?)
Please post a link to its manual
Please post a picture of the VFD control terminals showing the wiring
Please post a picture of the Motion Controller Output terminals and how they are wired.

My *hunch* is you did not wire the Inverter/Fault Reset properly and/or you did not program the VFD input that it is connected to to RESET the VFD. I am attaching schematic Excerpts from an All in One DC schematic.

If wired/programmed correctly, cycling your physical estop button should reset the inverter.

Thanks for all of the feedback.

What is confusing is that I have verified that once I power up the the inverter, that the inverter fault input is going green. There is not a fault on the VFD screen, it is ready to go.

I am using the Teco L510 drive.



Thanks,
Tim

Don't confuse a VFD FAULT INPUT (Telling the inverter there is a fault from the control) with VFD RESET.

Are you wired to VFD Input 5 RESET?

IF you are, then next time the VFD faults, take a jumper from VFD COM and touch it to VFD input 5. Does the VFD RESET? If it does, its your wiring from the control, if it does not, its likely something with the drive. Check to see that VFD INPUT 5 is programmed properly for RESET. AND double check your wiring from AIO DC

I think his point is that there is no VFD fault to reset. The VFD is fine.

The problem is that the Centroid PLC program has latched SpindleFault_M, and won't reset it.

In the PLC program he has been using, someone has commented out the code that resets SpindleFault_M in response to Emergency Stop.

He could edit it to fix that one thing, and hope there are not other similar issues; or he could just use the program that I posted.
