slide control Max. Velocity is sporadically overwritten with zero at startup

Hello
i have a problem maybe someone can help me
for me the slider is for max. Speed always 0 and can not change the machine Works flawlessly

After starting the screen 2-3 times, the controller works again until the next one
restart the screen

with G0 the maximum speed is driven
I believe that it is a problem loading the screen is working in Axis
slide regulator

Hallo,

I can not see, that you have an error in your config. The behavior you discrip is not known.
What distro and what window manager do you use?
