Re: problems with velocity readout from encoderget vi

Make sure that the " minimum rate" parameter is not set too high. We scaled our output to ftc/sec, so the default min rate was too big. If your measured rate drops below the min, the output is set to zero, and the "stopped" output goes true. Watch the "stopped" output.
