1. The first difference between a servo encoder (synchronous service motor) and an ordinary encoder is that it provides sensing signal feedback for the commutation of the starting current. The main performance indicators of servo motor encoders are shift rate, accuracy, and repeatability.

1) The conventional reference to 17-bit to 25-bit singleturn resolution encoders does not refer to the accuracy of the encoder, but to the resolution of the encoder. 17-bit encoders may have different finesse

(2) The accuracy of the servo motor encoder refers to the proximity between the measured value and the actual value, and there is no way to talk about the accuracy without comparison with the standard

(3) The repeatability of a servo motor encoder refers to the ability to reproduce the same result without changing the external state.

(4) It is generally believed that accuracy is more likely to be expressed in terms of "authenticity", and precision is often used to refer to "high repeatability and high precision".

2. What is the resolution of the servo motor encoder?

(1) Resolution refers to the distance generated between each counting unit of the encoder, which is the minimum distance that the encoder can measure.

(2) The sensor feedback required for the smoothness of the speed and acceleration of the servo motor requires the encoder to output a high-resolution signal set.

(3) The resolution of the servo motor encoder depends on the number of scribing (incremental encoder) or the encoder disc mode (absolute encoder). Generally speaking, resolution is a fixed value, and once the encoder is manufactured, there is no way to increase the number of lines or code. However, incremental encoders can improve resolution through signal segmentation.

(4) The high resolution of the servo motor encoder does not mean that it has high precision, and the encoder resolution and accuracy are two independent concepts.

(5) The high-resolution encoder is an internal high-resolution encoder based on the subdivision of the sine and cosine signals of the original signal, and the signal accuracy of the encoder depends on the acquisition method of the original signal of the encoder, the signal quality and the system accuracy, as well as the electronic error caused by the subdivision and compensation.
