The axis of rotation has no negative direction

I am a novice and am configuring a 5-axis program on raspberry PI 4 using GPIO to output pulses.
But in the simulation, I found that my axis of rotation had no negative direction, so that it always rotated 360°.
For example, if axis A moves from 30° to 0°, axis A will rotate 330° instead of -30°
I hope to get your help and I will be grateful.

Will need some config files to help sort it out. Hal and ini

    这是我的配置文件，我是通过Stepconf配置复制过来的，可能有点乱。

Just looked at this real quick. But how are you asking for it to go in a negative direction?

If your command is to move from A30 to A0 then it will move to that in a positive direction. It looks like if you were to ask for A-0 then it would go in the negative direction.

Also noticed you have in your INI "WRAPPED_ROTARY = 3" and was wondering what that means.

 

Thank you very much
The articles were very useful to me, and he solved my problem
"WRAPPED_ROTARY = 3" this should be wrong, I didn't notice

Thank you again for
