Pepperl+Fuchs encoder wiring analysis okplazas.com to share with you

Dear P+F Pepperl+Fuchs encoder enthusiasts, in view of the fact that some "compilers" are very concerned about the use of encoders. The editor of okplazas.com is here to share with you the wiring method of the rotary encoder. Let's take an example. For example: connect to PLC, take CPM1A as an example, the brown wire of the encoder is connected to the positive electrode of the encoder working voltage, the blue wire is connected to the negative electrode of the encoder working voltage, the output wire is connected to the input point of the PLC in turn, the blue wire is connected to the negative electrode of the external power supply, and the external power supply The positive terminal is connected to the input com terminal of the PLC.

As shown in FIG. A safe method can also be selected: Method 2: Connect the brown wire of the encoder to the positive pole of the power supply, connect the output wire to the input point of the PLC in turn, connect the blue wire to the negative pole of the power supply, and then pull a wire from the positive end of the power supply to the PLC input com terminal. The brown wire of the encoder is connected to the positive pole of the power supply, the output wire is connected to the input point of the PLC in turn, the blue wire is connected to the negative pole of the power supply, and then a wire is drawn from the positive end of the power supply to the PLC input com terminal. The specific wiring method is as follows: the brown wire is connected to the positive pole of the power supply, the blue wire is connected to the negative pole of the power supply, and then a wire is drawn from the negative end of the power supply to terminal 6; the black and white wires are connected to terminals 8 and 9, if automatic reset is required, orange The line is connected to the No. 7 terminal. Look at the output. The wiring of P+F Pepperl+Fuchs encoder has two groups of A. B. Z. Now there are 6 wires, +V, 0V and then FG. What should your encoder be connected to? Is it connected to a PLC, a motor, or a counter? Generally, the wiring is VCC connected to the power supply, line A is input A, item B is connected to the common terminal, item Z is a weekly pulse item, one pulse per week . If it is counting, you can leave out the Z item.
