There is provided a motor control system adapted for use, for example, with a sample analyzer, having means for generating signals representative of motor movement, and a logic circuit for analyzing the motor movement signals to determine increments of movement and the direction of movement. Digital circuitry is also provided for tracking the actual motor position as it is moved in either a forward or reverse direction, and comparing the tracked position with a programmed destination position. When and only when the motor is within a predetermined range of the destination position is a variable control generated, causing braking of the motor so that it stops exactly at the programmed destination position.
