7i96S card arrived what setup is recomended

Does whatever drives the contactor coils have arc suppression?
If not, this needs to be added or you will generate 100s of volts
of EMI field when the contactors turn off.

(this is a common situation if CNCing a non CNC machine)

Never worked with a 3 ph contactor.
It's a 3 ph contactor with 24v drive coil + flyback diode added.
The contactor coil on the video is not active (by 24v). I have pressed the contactor with my finger. And it's blinks when I'm turn it ON And it's blinks when I'm turn it OFF. (in the middle of the video you can see the blink - 7-8 sec turn OFF, 9sec turn ON)
How to find that arc suppression device?
Here is how it looks like. The 3 PH goes to the contactor, an then to the thermal relay. (under the inverter - that is all)
 

OK if there is a flyback diode on the contactor coil, the noise is likely coming
from the contact side of the contactor

If you cannot isolate the control wiring from the power wiring you
may need to either shield the control wiring or add arc suppression
to the contactor contacts (commonly a R/C snubber is used here)

Thanks for your advices!

But in my case the flyback diode and the coil are not working, because I switching ON/OFF the contactor by my hand (without 24v power supply) and the input LEDs are blinking.

I will try to shield it and somehow separate them.
The arc suppression looks like this? What resistance resistor and what capacity capacitor should I use? (if the manipulation wont be success)

We also bought 3 ph SSR...

2) The Spindle Close-Loop
There is a simple 3 ph AC motor and inverter. They are connected and turning the Spindle CW/CCW.
The Lathe has 3 speeds. On the first speed when I command to turn 200 rpm (almost 1:1 ratio), it's turning with 275  ±2rpm.
The scaling not correct yet. I will do it soon.
Is it possible to use the Close-Loop to use all speeds automatically, without using any other hal component.
(the lathe config will upload on monday.)
 

Here are the conf files.
