Encoder detects the disadvantages of the angular displacement of the shaft - News - Global IC Trade Starts Here.

Photocoupler

1. When the range of motor speed operation exceeds the allowable range, the waveform and frequency of the feedback pulse output by the encoder will undergo a qualitative change;

2. When the waveform and frequency of the feedback pulse change qualitatively, the relevant pulse processing circuit is invalidated;

3. The relevant pulse processing circuit fails. As a result, the number of pulses output by the encoder will be counted incorrectly, which is what we often call "interference"!

4, especially the high-resolution encoder, high-speed operation, even if it is an instant, it will lead to errors in the counting comparison instructions! Caused the servo control to fail!
