ec11 encoder performance description

The ec11 encoder consists of a photoelectric code disc with an axis in the center, which mainly uses the principle of photoelectric conversion to output three groups of square wave pulses A, B and Z phases. Therefore, if you generally need to improve the resolution of the encoding, you can use the A and B signals with a 90-degree phase difference for frequency multiplication or replace the application of a high-resolution encoder. Moreover, the ec11 encoder shaft will output a fixed pulse after one revolution, so the number of encoder grating lines determines the number of pulses. Then you may wish to learn about the performance characteristics of the ec11 encoder and related functional analysis together with the editor.

ec11 encoder performance description

1. Model output form

Under normal circumstances, the signal level obtained by the photoelectric detection device of its ec11 encoder is relatively high, and the waveform signal obtained from this is also irregular, which will cause difficulty in controlling the encoder, signal processing and remote transmission. Claim.

2. Identification of accuracy

Accuracy is the ability of a vector of ec11 encoder to confirm that any pulse is equivalent to the position of another pulse within the specified resolution range. General accuracy is usually expressed in angles, arc minutes or arc seconds, and has nothing to do with resolution.

3. The stability of the output signal

Generally, the stability of the output signal of rotating ec11 encoder refers to the stable ability of the encoder to maintain the specified accuracy under specific operating conditions. However, if it is impacted, the main reason for its stability is the drift caused by the temperature on the electronic device, the deformation force applied to the rotary encoder and the change of the light source characteristics.

4. Response efficiency

The response frequency of ec11 encoder input depends on the response speed of photoelectric detection device and electronic processing circuit. If the general ec11 encoder rotates at high speed, if its resolution is very low, the signal frequency input by the encoder will also change very low.

5. Resolution description

Secondly, the ec11 encoder is expressed by the basic cycle number of the output signal generated by one rotation of the shaft, that is, the number of pulses/revolution (PPR). The number of light-transmitting slits on the code disc is smaller than the resolution of the encoder. The more slits engraved on the code disc, the lower the resolution of the encoder.

About ec11 encoder function characteristic analysis

Feature One

Generally, the signal output of ec11 encoder can be obtained from the equipment circuit in most normal situations. Therefore, the general encoder only needs to be accurate in the position of the device in operation, and it can comply with the control signal processing and long-distance transmission. request.

Feature two

Secondly, the ec11 encoder can not only measure multiple control stations, but also outperform other ordinary encoders in terms of stable performance and service life.
