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

Re: Can Centroid Control this?
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...

Re: 9045 Z axis fault
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....

Re: E-stop will not work using N C switch
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.

Re: Wizard PLC function to change spindle direction and enable?
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.

Re: Help on isolation switch fit two circuits/power supplies
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...

Re: Delta ASDA-B2 ACORN WIRING INFORMATION
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...

Re: Help on isolation switch fit two circuits/power supplies
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...
