Configuring coolant motor with Mesa 7i96S and VFD YL620A

Hi All,I'm using Linuxcnc 2.9 with Mesa 7i96S and YL 620A. I want to run my coolant motor only when the spindle is running. Please suggest the edits needed.I'm newbie to linuxcnc configuration so pls suggest direct edits :-)Attaching my configuration files.

something like:

net spindle-is-on spindle.0.on hm2_7i96s.0.ssr.00.out-01

(assuming spindle.0.on has not already been connected to another signal
somewhere, I did not see it in any of the provided hal files)

And how shall it be connected ? which pins and all.... completely unaware

Do you mean the physical connections?
My example used SSR 1 so the output would be
OUT1- and OUT1+ on TB3 pins 15 and 16

How those outputs connects to the coolant control depends
on you hardware.
