Its function is similar to that of a frequency converter on an ordinary AC motor. It is part of a servo system and is mainly used in high-precision positioning systems. It generally controls the servo motor in three ways: position, speed and torque to achieve high-precision transmission system positioning. It is currently a high-end product in transmission technology.

[0003] In order to ensure the reliability of the servo drive, it is necessary to perform performance testing after production. During the performance test, different vibration reduction environments will also affect the test results of the servo drive, and the general performance test platform can only provide a vibration reduction environment or a vibration reduction environment, which leads to a relatively simple vibration reduction test result. Summary of the invention

[0004] The invention discloses a performance test platform for a servo drive, aiming to solve the technical problem that a general performance test platform can only provide an environment without or with shock absorption, thereby resulting in a relatively single test result in terms of shock absorption.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:
