Abstract

The invention discloses a filtering method and device for an encoder. Wherein, the method includes: controlling the motor to enter a self-inspection mode, wherein in the self-inspection mode, controlling the motor to be powered on and setting the motor speed to 0; obtaining interference data in the self-inspection mode, wherein , the interference data is data generated by interference to the encoder; the attribute information of the encoder is adjusted according to the interference data, wherein the attribute information includes: a low pass of a filter in the encoder Filter cutoff frequency or communication time of the encoder. The invention solves the technical problem in the prior art that a fixed filter frequency is set in a program to filter out the interference of an encoder, resulting in poor interference removal effect.

Description

technical field [0001] The present invention relates to the field of encoders, in particular to a filtering method and device for an encoder. Background technique [0002] A motor encoder is a device suitable for compiling and converting signals (such as bit streams) or data on a motor into a signal form that can be used for communication, transmission and storage. Since there is some interference in the communication process of the encoder, this part of the interference is usually filtered out. [0003] At present, the way to filter out motor interference is mainly to use an oscilloscope to test the frequency of the interference in the encoder communication waveform, then add a low-pass filter to the program, and set a fixed filtering frequency for the filter to filter out the interference of this frequency. Lose. [0004] However, since the source and path of the interference in the encoder are affected by various factors, the frequency of the interference on the encoder...
