Re: Victor Braking Feature
it is hard to have the motors "freeze". That is not what the jumper setting accomplishes. The following is from memory, don't take my word on it...
one setting feeds the power generated by the motor spinning back into the battery the other one, "dynamic braking", feeds the power back into the motor with reversed polarity, causing it to slow down faster So dynamic braking will not stop your arm from falling down, but it might help with preventing overshooting. To prevent falling, you have to power the motor slightly "upwards". You can either do this with programming (recommended) or by "calibrating" the joystick until the arm stops. |
