Thesteps-per-periodmatches the encoder in hand, which has 30 detents per full turn; the default value of 1 step/period resulted in every other detent doing nothing. A relative axis produces increments of +1 and -1, rather than the accumulated value useful for an absolute encoder with hard...

The absolute rotary encoder has a maximum resolution of 65,536 steps per revolution (16 bits). The multi-turn versions can detect up to 16,384 revolutions (14 bits). Therefore the largest resulting resolution is 30 bits = 230 = 1,073,741,824 steps. The standard single-turn version has ...
To ensure smooth drive performance, an encoder must provide a large number of measuring steps per revolution as the first piece of the puzzle. However, engineers must also pay attention to the quality of the encoder signals. In order to achieve the high resolution required, the scanning signals...
On many rotary encoders, when you will move it, you will feel a bump. These are known as steps. Most have 12 steps, but they can be up to 200. There are many types of rotary encoders available which are either classified as the output signal or the sensing technology. The one we ...
