the drawbacks of Shaft encoder detecting the angular displacement！

Shaft encoder detects the angular displacement of the drawbacks

     

1, when the size of the operation range of the motor speed exceeds the allowable range, the output of the encoder feedback pulse waveform, frequency will be a qualitative change;

2, when the qualitative changes that have occurred this feedback pulse waveform, frequency, resulting in associated pulse processing circuit failure;

3, the relevant pulse processing circuit failure, the results of the number of pulses output from the encoder counting error occurs, that is, we often say that the so-called "noise"!

4, particularly high-resolution encoders, high-speed operation, even if it is a moment, can lead to an error count comparator instruction! The servo control failure!
