Is it possible?

What about converting the value that goes out into speed?
V=D/T
So if I divide the value it would be acceptable...:S
I don't really know much about PID
I can't attach a servo to the motor because it will be moving a big gear...How can I do this :S

The problem is that motors are controlled by speed, while servos are controlled by angle or position. You must have an encoder or some other kind of position sensor on the motor for this to work.

If you have that, you can subtract what the software thinks is the middle point (85 I think). Assuming the motor is pointing straight at the beginning, that is the setpoint for the encoder. If it's negative, turn the motor in that direction and vice versa. Once the encoder gets close enough to the setpoint, stop turning the motor so it doesn't oscillate.

Okay, so how do I do this exactly?
Where should I connect the encoder? Because the globe motor won't have a transmision...
And how do I make the change in labview? :S

Hey guys.... I can't seem to fix this
