I try to setup my jogging device and want to use mcJogVelocityStart to move either in the positive or negative direction. I see, that MC_JOG_NEG does not work, I have to use MC_JOG_POS a seconds time instead. Also the Mach4 Core Api documentation for function mcJogVelocityStart uses two times MC_JOG_POS to switch from positive to negative direction. MC_JOG_STOP does not work in my case also, it continues to drive in one direction.
Is there a correct or better way to guide the machine into the right directions during jogging?
Thanks for any ideas.

Could solve it by myself. It was a mismatch of parameters, sorry.
