I can set my accel and decel times down to 1/2 second and the lathe motor will start and stop in that time once I got all the parameters set correctly. The only 'problem' with setting the times so short is that the weight/mass of the spindle/chuck and drive train can't keep up with the motor and it will squeal the drive belt. Sort of akin to getting a fully loaded freight train rolling from a dead stop, or trying to stop one (quickly) when it's at full speed.
