if you had searched, you would have found that immediately, instead of having to wait half an hour.

if you would like to prevent the backdriving of the motors there is a function built into the speed conttroller specifically for doing this. what it does is short the motor when no power is being given to it. this acts as an electronic brake and makes it very hard for the motor to backdrive. all you have to do is swicth the jumpers from bc to ab. i hope this helps.

The window motors don't backdrive. They have play inside to utilize a clutch spring in case a little kids hand gets rolled up in the window. The gear is not driven by a shaft, it is driven by a cog which is driven by a shaft and that is why there is play. Dynamic breaking will do nothing to help it.
