Abstract: Taking the problem of angle jump electromagnetic interference encountered in servo drive system as the research object, the influence of circuit and components, filtering, shielding, wiring, grounding and other factors was explored. It was determined that the high-frequency noise of the + 24V DC power supply output by the AC / DC power module was the main electromagnetic interference source that affected the differential signal of the encoder. By taking corresponding filtering measures, in the case of changing the existing design in a small range, the effectiveness of the
suppression measures adopted by the servo drive system was verified, which can provide reference for electromagnetic compatibility problems in similar cases.

Key words: servo drive system,electromagnetic compatibility( EMC), electromagnetic interference( EMI), interference suppression
