Bah!
So I've googled some, and I must say, I don't really understand the noise thing. Does the noise only or mostly travel through the cables? Or is it i.e. radiating noise from the spindle through air?
I tried maximising the distance between the VFD and the spindle, and changing the RS+/- cable to a shielded and twisted cable. However, without results.
It seems that as soon as I turn on the spindle, the modbus/mach3 freezes. Doesnt matter if I turn it on though mach3, or manually on the VFD (however, the RS+/- cables are still connected through modbus)
I see from earlier in this thread that people have had the same problems as me, but as far as I can see, there was no solution. Or at least none told about it here.
Anyone else have an idea that I can try? Or is the next step adding some ferrite donuts around the all VFD-cables?
I really want this to work
Thanks for any input!! Its greatly appreciated
