Why does jog the x-axis follow when the c-axis moves?

I used the xyzac TRT five axis kinematics algorithm, but when I jog the X axis and then jog the c axis, the X axis and C axis will move at the same time. I don't know why. How should I change the c axis by jog moving it alone. Also, when I was at home C, he would only be at home first, and then home C would not return to zero. Unless jog moves the x-axis and c-axis, I can make the c-axis return to zero, which also annoys me. 

Or how can I move x, y, Z, a, C separately without disabling remote operation mode? I hope someone can help me, thank you.
