Wiring method:
The encoder has 5 leads, of which 3 are the pulse output line, 1 is the COM terminal line, 1 is the power line (OC gate output type). Encoder power can be an external power supply can also be used directly PLC 24V DC power supply. The "-" terminal of the power supply should be connected to the COM terminal of the encoder and the "+" should be connected to the power terminal of the encoder. The COM terminal of the encoder is connected with the PLC input COM terminal. The A, B, Z two-phase pulse output lines are directly connected with the input end of the PLC. A and B are pulses with a phase difference of 90 degrees. The Z phase signal rotates only once in the encoder A pulse, usually used to do the basis of zero, when connected to pay attention to PLC input response time. Rotary encoder there is a shielded cable, shielded cable to be used when used to improve anti-interference.
