摘要：In an encoder output method and a servo motor encoder according to the present invention, the number of signal lines is reduced by using common signal lines and common output terminals. In the encoder output method and the servo motor encoder, incremental signals (A, B, Z) and servo motor magnetic pole position detection signals (UE, VE, WE) are switchably output by a common driver (2) through a pair of timers and a multiplexer (30), or a pair of timers and two line drivers (60, 70) are selectively active or inactive, and common signal lines are used, thereby reducing the number of signal lines. <IMAGE>
