Connection button, accelerator, brake on simucube

I configured MMos
I have connected potentiometers X11 upper
It works very well.
Pin 1 brake - rotation X
Pin 2 accelerator-rotation Y
Pin 4 clutch - rotation z

When moving the axis of the motor Migue 130ST moves the AXIS X

I want to connect a further potentiometer to pin 3 or pin 5 of the X11 connector upper, but it does not work.
Do you have to configure something?

A greeting.
