I would suggest trying the snubber circuit modification from this post: viewtopic.php?p=46032#p46032

If that fails, then a signal isolator might be the ticket. Some options are posted in this thread: https://centroidcncforum.com/viewtopic.php?f=60&t=10170

I think you might have to request a spec sheet from Heidenhain but from the dimensional drawing/mounting instruction sheet ( https://product.heidenhain.de/JPBC/image/HWP.DE/hlr-system/id-nr.281593-94_rod_450-456.pdf ), it is a sine output so it will need to be changed or converted. You will probably...

Glad you are up and running! Feel free to post photos of the machine and things you make.

Thanks eng199, this is a huge help, you really saved my day. Wire came loose inside the cabinet, i think i...

My centroid control PC decided to do a windows update this afternoon. After that, every time I try and start a program in CNC12 Mill, I get a 9045 Z Axis Drive Fault error. The system no longer moves. Was working all week without issue. The timing coinciding with a windows update is too suspicious....

Go to the input assignment page and click on the green circle next to your EStopOk input. It should turn red indicating that it will function as NO.


ACORN will have 8 inputs here but the picture should help you get to the right place.

There's two paths that I can see:
1. Wire to the output relays and choose the NO or NC contact depending on whether or not the enable input needs to conduct to be on.
2. Find the line in the PLC and invert the behavior.

Mine is a Chinese vfd it's a huanyang one so I don't think it has a breaker within it apparently most the Chinese stuff don't. Over time I will be replacing them when I can afford ro spend but I just wanted to get back up and running. I think you might be able to find a matching manual on the follo...

It is not a good idea to have an inductive load (i.e. relay or contactor coil, DC motor, etc) without some means of protecting from the energy spike that results when the current is cut off. At best you will introduce noise that could interfere with the other equipment and at worst there is the poss...

I can answer two of these: There should be formulae to calculate the required braking resistor or a table listing the values in the VFD manual. Depending on what series of VFD, it might have the braking resistor built in. You can assign one of the output relays to "SpindleCoolingFan" and i...
