So, I am thinking for the Spindle to run through Kanalog/KFLOP I need wire #217 connected to JP13 Opto Output (I will be use # +7) which will:
1.) Wire #217 must be connected to Kanalog JP13 Opto Output (# +7) so when KFLOP reads a "M03" and "S" NC Code -- this JP13 Opto Output (# +7) would provide +24VDC to wire #217 (which is connected to 13CRE relay).
2.) So when wire #217 on 13CRE relay gets +24VDC then wire #218 on 13CRE relay would have +24VDC -- which in turn would feed wire #218 connected to 12CRE relay which would turn 12CRE relay on.
3.) Once 12CRE relay is on then wire #243 would connect to wire #242 which is also connected to 12CRE relay and the other end of wire #242 is connect to DI2 on the VFD terminal.
4.) And the wire #242 get +24VDC from the VFD +24VDC terminal because ....
5.) Wire #243 and wire #241 are connected together just outside of the VFD (separate from the VFD bus terminal).
6.) However, since 1CR relay is on at this point, wire #240 (which is connected to the VFD +24VDC terminal), now has +24VDC from the VFD +24VDC terminal which in turn feeds wire #241 on 1CR relay (when on) with +24VDC.
7.) So, I am thinking this is how wire #242 on 12CR relay gets the +24VDC from the +24VDC VFD terminal, which is connected to DI2 terminal on the VFD.
This LINK has the 1CR, 2CRE, 12CR, and 13CRE relays wire pin for quick reference (see last 4 images of link).
