Abstract

PURPOSE:To reduce follow-up delay and to improve reply efficiency, by constitution so that a signal following a command position from a computer and a speed signal up to the command position are obtained as a constant speed signal decided by a command position signal. CONSTITUTION:Latching circuits 2, 3 hold a command signal from a computer alternately whenever a data updating signal is outputted. As for outputs of the circuits 2, 3, its difference is fetched by a subtracting circuit 4, and in case when its difference has become a complement, the complement is converted to a real number by a complement converting circuit 5. A result of substraction obtained in this way is converted to an analog signal proportional to an input, by a D/A converting circuit 6. On the other hand, a command position signal and a device position signal are inputted to a comparing circuit 7, its magnitude is compared, its compared output is inputted to the circuit 6, and form its compared output, the polarity of an output signal of the circuit 6 is decided. In this way, a signal following a command position from the computer and a speed signal up to the command position are obtained as a constant speed signal decided by a command position signal.
