Zuercher,
If Gene is right, then there is a really big loop area. Ether the leads to the
motor / drive are taking different paths or the is a big ground loop some place.
You could try moving the leads around to confirm what Gene is suggesting. If
this is the case, check for ground loops. If
Hi Russel,
I got exactly the same troubles describes with the VFDs creating a lot
of perturbation. Aspiration was also making perturbation for me.
Thankfully at my work place we have experts on EMI and Stephen advices
are what you need to follow.
In my case, to solve it I had to shield the cable
someone had started this...

EMI. VFDs generate lots of it. You're likely getting lots of noise coupled
into your limit switch cabling. Shield the vfd wires if possible. Running in a
shielded single cable is probably best. Separate the motor and switch cables as
much as possible too.

You could also put a reactor between the motor and drive. Might be a good idea
to put a line filter on the power leads to the drive too.
I'm not a fan of shielding, but it's certainly an option as well.

VFDs and AC servo drives oftentimes create noise on the incoming AC
power lines to the drives.That noise can cause interference issues
with system electronics.
I recommend you purchase an incoming line filter to keep the noise from
backing up into your AC power line.
This is a filter I

Almost certainly EMI. An input filter for the VFD can help. Check eBay for
Rasmi they are not expensive.
If your mill is not downstream of an RCD then I have one spare you can have.
My 2'X4' CNC router has a 2.2 KW water cooled spindle and VFD - the
typical Chinese kit off eBay.

Hi all,
I will close this thread out. I was able to get the manuals through BK.
Apparently what you have to do (I won't get a chance to try it until Monday)
is hold two buttons on controller boot, which will put it into program mode.

Looks like it won't be coming with the big, black controller box so a

and in the mill itself.
Then there's the spindle speed control, which ran on a
