摘要： A velocity servo comprising a servo drive package (7) including a servo motor (8) and a feed back loop including a tachometer (9) coupled to the servo motor (8). An analog velocity command (6) and a command pulse train (21) are generated by a velocity profile generator (1) and the command pulse train (21) and a feedback pulse train from a pulse generator (10) are connected to a position error counter (11) which compares these pulse trains and generates a digital output representative of the difference therebetween. This digital output is transformed to an analog position error signal (22) having the correct polarity, and an operation amplifier (13) sums the velocity command and the position error signal to drive the servo drive package (7).
