Thread: noise from motor controller?

  1. noise from motor controller?

    I am running a Sabertooth 2x25 from an Arduino. I am sending PPM signals from the Arduino (with the servo library) and the Sabertooth is in R/C mode. When I start the motor going full speed, it runs in one direction, but it jerks around a lot. In the Sabertooth documentation, it says that if you are going to send it PWM from a microcontroller, then you should put a small RC (resistor capacitor) circuit in front of the microcontroller output. Does this problem sound like it is from excess noise somewhere in the circuit? And if so, would a small RC circuit help?

  2. Re: noise from motor controller?

    Whoops, turns out I forgot to ground the Arduino to the Sabertooth! Doh!

    Re: noise from motor controller?

    Additionally, the output generated from the Arduino servo libraries is a PWM (width) signal, not a PPM (position) signal. If it were PPM, the Sabertooth might get a little confused.
