ABSTRACT:
A system for accurately stopping a motor operated positioning device permits satisfactory motor tolerance limits for economical production by incorporation of a processor controlled motor plugging routine. The plugging routine includes an initial reverse polarity pulse to the motor of a duration sufficient to brake an ideal motor operating in the device. To accommodate motor characteristics within tolerance limits, a plurality of alternating bursts of positive and reverse polarity are applied to the motor following the initial pulse. Each of the alternating bursts is for a duration less than the system response time.
