Abstract

The invention relates to the technical field of encoder application of a servo control system, in particular to a zero pulse generation method of an absolute value encoder, which can flexibly generate a corresponding zero pulse width according to the real-time speed of the absolute value encoder according to the number of actually-set pulses expected to be output in each circle, and can be used for generating a zero pulse according to the real-time speed of the absolute value encoder. Compared with the traditional fixed zero width, the use error is greatly reduced; moreover, the method is suitable for various types of absolute value encoders, can be applied only by changing the corresponding absolute value encoder resolution r and communication period t into the information of the current absolute value encoder, is high in compatibility, and reduces the use cost.

Description

technical field [0001] The invention relates to the technical field of encoder application in a servo control system, in particular to a method for generating a zero-point pulse of an absolute encoder. Background technique [0002] Absolute encoders are more and more widely used in servo control due to their extremely high resolution and position memory function. [0003] In servo applications, the upper controller sometimes needs to receive the encoder zero pulse output by the servo to realize the logic control of the system. Since the position of the absolute encoder is collected through data communication and there is no actual pulse, it is generally realized by calculating the generated encoder zero pulse. The current general method is: compare the two acquired absolute encoder positions, once the position is found to cross the zero point, generate the edge of the zero pulse, and then define a pulse width to complete the generation of the zero pulse. [0004] However, ...
