Title: COMMUNICATION APPARATUS AND MOTOR CONTROL APPARATUS
Abstract:
A communication apparatus (100) of the present invention is provided with a first communication circuit (2), a second communication circuit (1), and one signal line (3). The first communication circuit (2) transmits, as an output signal, a collector voltage of an open collector circuit. The second communication circuit (1) receives the output signal. The one signal line (3) connects the first communication circuit (2) and the second communication circuit (1) to each other. Specifically, the first communication circuit (2) transmits the output signal, as a pulse signal (57), to the second communication circuit (1). The second communication circuit (1) transmits a voltage signal (56) generated by means of the second communication circuit (1) to the first communication circuit (2). The first communication circuit (2) and the second communication circuit (1) bidirectionally communicate the pulse signal (57) and the voltage signal (56) therebetween via the signal line (3).
