The rotary encoder is a testing device, has been widely used in various fields, rose today to share with Electronic rotary encoder and installation diagram illustrating the rotary encoder wiring step.
Output pulses to rotate the rotary encoder, the counting device known by its location (PLC), we usually use the incremental encoder, incremental encoder output pulse signal is directly input to the PLC, the use of PLC its high-speed counter counts pulse signals to obtain measurement results. Since the number of the rotary encoder output pulse is different, and some rotary encoder output A, B, Z phase pulse, and some only A, B two-phase, only the A phase easiest. Up to A, A +, A-, B, B +, B-, Z, Z +, Z- three sets of three-phase pulse.
Common rotary encoder has five leads, where 3 is a pulse output line, a COM is the end line, a power cord (OC gate output type). Power source may be an external power supply, can also directly use the power of the PLC. Power "-" terminal to be connected with COM encoder "+" power supply terminal and encoder connections. COM of the encoder and the PLC COM input terminal is connected, A, B, Z two-phase pulse output is connected directly to the input of the PLC, A, B is 90 degrees pulses. There is a rotary encoder shielded cable, the use of shielded wire to the ground, improve immunity.
Rotary encoders installation steps:
1. securely mounted encoders to avoid jarring loose;
2. When the encoder connection, make sure that the load can not exceed the maximum allowable value;
3. When the encoder connection, make sure there is no bias;
4. Lock the coupling screws to avoid loosening during use.
