PURPOSE: To use only one signal conductor, and to reduce space by giving specified potential to the signal conductor by an output from an encoder, controlling a drive section and transmitting the quantity of operation.
CONSTITUTION: Encoders 4a are installed to motors 4. Positional-signal generating circuits 3 grounding a rotational signal from a control section 2 by signals from the encoders 4a are mounted to a drive section 3. An operation-quantity signal can also be detected even in the control section 2 by grounding the rotational signal. The operation-quantity signal are counted by a micro-computer 2a, and the quantity of operation is acquired and compared with the fixed quantity of revolution held in the micro-computer 2a set by an operating section 1, and a stop signal is generated from the micro-computer 2a when both quantities coincide.
