Dont know anything about the Kanalog and not really going to study it in detail as I will be unlikely to ever use one I am afraid.
I can say however that JP6 says its analogue inputs and in Mach they would be used for things such as Feed Rate Override pots, Spindle Override pot etc in conjunction with a macropump or a Brain.
JP11 is the analogue outs and that is where your -10 +10 signals to your Amps connect to.
Tool changers and other I/O would have to be connected to the other locations (JP8, 13 and 15)
