Pepperl+FuchsEncoder malfunction: refers to the failure of the encoder's components, which prevents it from generating and outputting the correct waveform. In this case, it is necessary to replace the encoder or repair its internal components.

2. Encoder connection cable fault: This type of fault has the highest probability of occurrence and is often encountered during maintenance, and should be a priority factor to consider. Usually, it is due to open circuit, short circuit or poor contact of the encoder cable, in which case the cable or connector needs to be replaced. Special attention should also be paid to whether the loosening caused by loose cable fixation leads to welding or circuit breaking. In this case, the cable should be clamped tightly.

3. Encoder+5V power supply drop: refers to the situation where the+5V power supply is too low, usually not lower than 4.75V. The reason for the low voltage is due to power supply failure or high resistance of the power transmission cable, which causes losses. In this case, the power supply needs to be repaired or the cable needs to be replaced.

A rotary encoder is a photoelectric rotary measuring device that directly converts the measured angular displacement into a digital signal (high-speed pulse signal).

Encoders can be classified based on signal principles, including incremental encoders and absolute encoders.

We usually use incremental encoders, which can directly input the output pulse signal of the rotary encoder to the PLC, and use the PLC's high-speed counter to count its pulse signal to obtain measurement results. Different models of rotary encoders have different numbers of output pulses. Some rotary encoders output three-phase pulses of A, B, and Z, while others only have two phases, A and B.

The encoder has 5 leads, including 3 pulse output lines, 1 COM terminal line, and 1 power line (OC gate output type). The power supply of the encoder can be an external power supply or directly use the DC24V power supply of the PLC. The "-" end of the power supply should be connected to the COM end of the encoder, and the "+" end should be connected to the power supply end of the encoder. The COM end of the encoder is connected to the input COM end of the PLC, and the A, B, and Z phase pulse output lines are directly connected to the input end of the PLC. A and B are pulses that are 90 degrees apart, and the Z phase signal has only one pulse when the encoder rotates once, usually used as a basis for zero point. When connecting, attention should be paid to the response time of the PLC input. The rotary encoder also has a shielded wire, which should be grounded during use to improve anti-interference performance.
