Abstract

PURPOSE:To make accumulated errors zero for performing an accurate synchronous drive of motors, by transmitting a set pulse from a main motor to a subsidiary motor through a counter and effecting a speed control in accordance with the difference between the set pulse and the detection pulse of the subsidiary motor. CONSTITUTION:A detection pulse 8 and a set pulse 9 are fed to a counter 12 to obtain a pulse number deviation. Moreover, difference between latch signals are accumulated in a counter 13, thereby to control motors 1, 2 through an adder 14, a register 15 and a D/A converter 16. In addition, the set pulse 9 of the motor 1 is transmitted as a set pulse 9' of the motor 2 through a counter 18. Moreover, the detection pulses of both motors 1, 2 are fed to the UP and DOWN terminals of a reversible counter 21 through a counter 19 in order to obtain the difference therebetween for driving the motor 2. Accordingly, it is possible to make accumulated errors zero with respect to any type of deviation, so that an accurate synchronous rotational speed control can be effected.
