RC Hobby servo is connected to controller's motor positive and negative inputs (PWM input is left out)


An RC hobby servo will not do anything until you give it a pwm input signal telling it what to do.  With that left out, you have a nonfunctional servo.

I'm not even sure what a servo will do if you power it from high frequency PWM instead of DC.
I assume the OP was going just set the PWM to 100%.
Can't think why you'd want to do it though - seems a very expensive way of powering a servo.
