ABSTRACT:
A digital position control for linearly moving apparatus driven by a motor includes a command signal generating loop coupled to a motor operative condition control loop. The command signal generating loop provides a digital pulse train signal having frequency characteristics corresponding to the desired accelerations and velocities of the apparatus and a total number of pulses proportional to the desired movement of the apparatus. The motor operative condition control loop employs the command signal to energize the motor in accordance with the frequency and pulse count characteristics of the command signal.
