In your setup you would leave pin 4 of the terminal block unconnected. Setup Mach3 to use pin 16 as the motor enable/disable control. I don't have Mach3 with me right now to verify, but you may need to toggle the active high/low option to get it to work right. Just flipping that back and forth should enable/disable the motors as you do it.
