8.8 Accuracy of the Encoder System
This chapter describes which individual factors influence the accuracy of the encoder system and how to improve them.
Accuracy is defined as the difference between measured angle and actual angle. This is not to be confused with resolution, which is the smallest
step that the system can resolve.
The two parameters are not necessarily linked together. A high resolution encoder may not necessarily be highly accurate as well.
8.8.1
Quantization Error
There is however a direct link between resolution and accuracy, which is the quantization error:

The resolution of the encoder determines the smallest step size. The angle error caused by quantization cannot get better than ± ? LSB. As
shown in Figure 28 , a higher resolution system (right picture) has a smaller quantization error, as the step size is smaller.
For the AS5030, the quantization error is ± ? LSB = ± 0.7°
