Victor brake feature

[Japper]

How well does the victor brake feature work?

I connected a motor which is raising a lift to a victor and set the brake jumper but I am not sure if it is doing much of anything as the lift still does slowly drift down due to the weight of the lift...

Is this brake feature limited in how much slippage it will allow when a 127 value is sent to the victor or am I doing something wrong?

Is there a way to incorporate a mechanical brake?

Any ideas would be appreciated

Thanks

The brake feature essentially shorts the terminals of the motor together when the victor is stopped. The idea is that the motor auto generates a reverse emf from whichever direction it's turning and it uses this to "brake"... it's actually just making it harder to turn at stop so it will still move since its a small but effective electrical brake. Since you're overpowering this then it sounds like you do need to incorporate some kind of mechanical stop.

The brake mode on a Victor simply puts an electrical short across the motor. (actually about .012 ohms) Any current generated by the motor is then shorted by this feature causing dynamic braking in the motor. Motors at high speed generate more current than a slow moving motor does, thus dynamic braking is greater at higher motor speeds. High gear ratio transmissions add to this effect.
There are a variety of ways to add a mechanical brake. Search other posts for "brake" and I am sure you will find some. Even a lowly servo can be used to engage a mechanical stop.

Good call Al... Servo is a great idea... ( I need to remember that!)
