Connecting my 7i96s to the VFD

Hi,

So I got my spindle and VFD wired up as you mentioned but as I am new to LinuxCNC I don't know how to set up my LinuxCNC to run my spindle. I am using 7i96s_5abobd.bin firmware if that has any impact on this. Thank you for being so helpful.

You should be able to use pncconf to setup your spindle
The firmware does not affect the spindle setup as the analog
spindle setup would be the same regardless of firmware.

A possible exception would be if you used the breakout board
to generate the analog spindle control voltage, but this would
really only make sense if you needed two analog outputs.
 

Ok thanks for the tip. I tried to setup the spindle via pncconf but it didn't run. I have a screenshot below of what I tried. In the TB1/TB2 tab I selected spindle PWM as you can see. Is this the wrong place to setup the spindle?image missing https://i.ibb.co/C5HxS8D1/Spindle-Setup.png

What do you have selected to enable the spindle?

Typically you need one output for single direction spindles 
and two for reversible spindles.

On a 7I96S, in hal, these would normally connect to the isolated
outputs on TB3, which in turn need to be wired to appropriate
VFD control pins.

Yes I have made the following connections

22 - SPINDLE- to COM
23 - SPINDLE OUT to AI1
24 - SPINDLE+ to +10v
and
S1 --> OUT4A
OUT4B --> COM

S2 --> OUT5A
OUT5B --> COM

So with this done, I set Spindle PWM as in the below picture but the spindle doesn't move when I run the config and try the + and - buttons for the spindle. Any ideas would be greatly appreciated. Thanks

You still need to connect OUT4 and OUT5 to the appropriate 
spindle pins in hal (via the TB3 tab in pncconf)
