Re: Using Digital Output to control Brake/Coast on Victor

I believe you need to connect a digital output of the RC to the center pin of the Victor "Coast/Brake" connector (which is male on the victor, so you'll need a double-femals PWM cable, but a single-pin cable is all you really need).

Then, set the pin High or Low depending on whether the brake is on or off.

Remember this is dynamic braking: Brake off means "Open circuit" when Victor is at 127, Brake on meand "Short Circuit" when vistor is at 127.

A DC motor acts like a generator - a short will cause the generator load to be high and cause a braking effect. The force depends on the speed of the motor - high speeds generate a lot of power and thus a lot of braking, low speeds generate virtually no braking effect.

Search the forums for more info on both points.

Don
