Overide analog input from joystick with script and then return command to joysti

Using a joystick to move an arm. Two axis of motion- CW/CCW and up/down. I cant have it run into a fixed object, so when it gets near the object its location will be given by a certain voltage no an analog input. I then need to override the joystick command and stop one axis of motion and allow the other to remain functional and move above the object until its clear and then reenable both axis. Is this possible. Is there a command to enable/disable a motor if an input is in a certain range. thanks

thanks, that works pretty well. I was stuck thinking about disabling the motor rather than the input that controls the motor. But when I run the motor with the joystick and change the analog3 input to cross the 2500mV threshold set in the code, the motor command locks at whatever value its at then. The motor just runs on its own until analog3 drops back below 2500.

top:
analog3=getvalue(_AI,3)
If analog3>2500 Then
setconfig(_AMOD,1,0)
Else
setconfig(_AMOD,1,2)
End If
GoTo top

Try this:

TOP:

analog3 = getvalue(_AI,3)

if(analog3>2500)then
do until analog3 <=2500
setconfig(_AMOD,1,0)
analog3 = getvalue(_AI,3)
loop
else
setconfig(_AMOD,1,2)
end if


GOTO TOP
