Rotary encoder is a kind of test device, is widely used in various fields, today electronic installation figure to share rotary encoder and the illustration of the rotary encoder wiring steps.
Rotary encoder to turn the output pulse, through counting device to know its position (
, we usually use are the incremental encoder, type of incremental encoder output 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.
Because the rotary encoder 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.
Most have A, A +, A minus
Three groups of three-phase pulse.
Commonly used rotary encoder has five leads, three of them are pulse output line, 1 is COM back line, 1 is the power cord (
OC gate output)
Power supply can be an external power supply, also can directly use the power of the PLC.
'end to the encoder COM end connection,' + 'connected to the power supply end of the encoder.
Encoder COM end connected to the PLC input COM port, A, B and Z two-phase pulse output line is directly connected with the input end of the PLC, A and B to differ 90 degree pulse.
Rotary encoder and a shielding wire, shielding wire to be used when grounding, improve anti-jamming.
Rotary encoder installation steps: 1.
Firmly encoder, in order to avoid vibration and loose;
When the encoder connection, please make sure that the load should not exceed the maximum allowable values;
When the encoder connection, please make sure that no deviation;
Lock the screw in order to avoid in use process of the coupling is loose.
