The electronic pulse of the feedback physical pulse of the encoder is expanded and the resolution and resolution are not improved! -Solutions - Huaqiang Electronics

1. "Electronic subdivision" is equivalent to expanding the number of physical pulses of the encoder detection feedback;
2, for example, the encoder of the line 1000, the weekly detection feedback 1000 physical pulses, the reading is expanded 10 times, into 10,000 pulses;
3. Then, every time the encoder feeds back one pulse, it is expanded by 10 times and becomes 10 pulses. What is the position of the first, second, third, ... 9 pulses after the expansion?
4. When the encoder feeds back 1 pulse, there will be 10 pulses after expansion. You can't see the enlarged 1, 2, 3, ... 9 pulses and their positions at all. You will only see the 10th. Number of pulses and their position;
5, or say that the number of feedback pulses of the encoder is 1, 2, 3, ..., 10 times the number of pulses after electronic subdivision is 10, 20, 30, ..., you can not see the subdivision :
1, 2, 3, ..., 9
11, 12, 13, ..., 19
21, 22, 23, ..., 29
6, electronic subdivision, is a deceptive number, the resolution of the encoder is still 1000, the resolution is still 1 / 1000, the resolution of the encoder will not be 10 times 10000, the resolution will not be 10 times 1 / 10000;
