If you are lucky, the following should work and if it doesn't, it won't hurt anything.
Connect the DCM to COM (Drive Interface: 10V ground)
Connect S1 to V1 (Drive Interface: 0 to 10V output) - Should be as simple as this.
The slide switches and lack of other wiring indicate that the VFD is set up to receive a 0-10 V input. The VFD does not seem to have the options of 4-20mA OR pulse/direction signaling. DCM is commonly referred to as 0V (or signal ground) in Chinese electronics (in my experience)
If you have a voltmeter to test the 0-10V output from the Motion Card, it would be good knowledge to have.
BTW, I believe that the Spindle Input would only be necessary if you have a closed-loop (system controlled/monitored) high accuracy spindle control set up. If you don't need to do this, I wouldn't at this time.
Good luck, it should go OK. I don't have the manual for this VFD but mine is somewhat close in many aspects. Since the are differences, and assuming it worked before, the parameters and such should all be adequate for your needs.
BTW, if the spindle runs backwards, reverse any 2 of the 3 motor leads.
