3 Terms and definitions
Zero error of the encoder.
The zero error of the encoder refers to the angular position of the encoder when it returns to its zero position from different positions in the positive and negative directions.
The maximum amount of change.
4 Overview
The encoder is mainly used as a measuring element with a grating disk or a code wheel for measuring the rotation angle. It can be used as an angle alone
The measuring instrument can also be used as a corner measuring component of a certain equipment or instrument. The principle and structure of the encoder are shown in Figure 1.
Show. According to the indexing error, the encoder can be divided into 7 levels.
5 Measurement characteristics
5.1 division error
The indexing error requirements of the encoders at all levels are shown in Table 1.
5.2 Angle repeatability
The angular repeatability requirements of the encoders of each stage are shown in Table 1.
5.3 encoder zero error
The zero error of the encoder is specified in the manufacturer's product standard and can also be determined by the user as needed.
5.4 Angle return error
The angular return error of the encoder is specified in the manufacturer's product standard, and can also be determined by the user according to the need
