The encoder manufacturers introduce connection principle and steps of the encoder
Encoder is applied to the speed control and position control system of detecting element. Encoder, such as signal principle to points, with incremental encoder, absolute encoder. Encoder wiring principle of the encoder is rotating measuring system, it will be converted into digital signals directly measuring the angular displacement of ( High speed pulse signal) 。 So the output of the rotary encoder pulse signal can be directly input to PLC, using the PLC high-speed counter to count the pulse signal, in order to obtain the measured results. Different models of rotary encoder, the output pulse phase number is different, some rotary encoder outputs A, B and Z three-phase pulse, some only A and B phase two phase, the simplest only A phase. Shown are the two pulse output rotary encoder and FX series PLC connection diagram. There are four lead coder, 2 is pulse output line, 1 is COM back line, 1 is the power cord. The power of the encoder can be an external power supply, also can be directly use PLC DC24V power supply. Power '- 'end to the encoder COM end connection,' + 'connected to the power supply end of the encoder. The encoder COM end connected to the PLC input COM port, A, B two phase pulse output line is directly connected with the input end of the PLC, to pay attention to the response time of the PLC input connection. Some rotary encoder and a shielding line, shielding wire to be used when the grounding. Encoder wiring operation steps: 1. Set address, connection mouth down with encoder, the left dial the code is ten, dial the code is a bit on the right. 2. Set terminal: only access line, the encoder is terminal, hit ON both terminals; Into wire and wire are two dial the code is set to 1. 3. Connection: 1) The terminals of the accessory order set of the DP line 2) Stripping DP line the outer rubber layer 10 cm 3) The inner layer of metal shielding layer, repeatedly and twisted into a 4) Strip line inside white protective layer, shielding layer connects to mark on the screw of the ellipse, and cable, A green line, red line B. Shanghai electronic products for 27 years old, encoder manufacturers, specializing in the production of various types of encoder. Magnetoelectric encoder, can according to customer's requirement to customize for incremental type magnetoelectric encoder and absolute type magnetoelectric encoder, pulse precision and size can be customized according to customer requirements. Magnetoelectric encoder used in robot, automatic production lines, automatic assembly machine, elevator, textile machinery, sewing machinery, packaging and printing machinery, CNC machine tools, mapper and Angle measuring instrument, etc. This encoder is also can be in PLC application as the high speed signal input element, make PLC more quickly and accurately implement the closed-loop control. Looking for a rotary encoder manufacturer is looking for electronic.
