Fig. 3-13 4 types of typical incorrect wiring 3.4.7 Frequency division output circuit of CN4 encoder Table 3-9 Description of frequency division output signal of the encoder The frequency division output circuit of the encoder outputs differential signal through the differential driver and open-collector signal through the transistor. Commonly, when a control system is formed with the higher-level device, feedback signal is provided. In the upper computer, please use a differential or optically coupled circuit or NPN circuit based on the signal type selected to receive the signal. The maximum current of differential output is 20mA; the maximum current of open-collector output is 40mA. Fig.
