Question:

What's wrong with the servo motors?

In the competitor's wheel mode, when the handwheel stops feeding, the motor is noisy, sometimes noisy and sometimes noisy. What's the matter?

Answer:

Proper reduction of the speed differential gain can solve the problem, but not too low. A phenomenon like resonance occurs.Essentially, the problem is that the servo gain parameter does not match the external load. To make the perfect adjustment, the procedure is:1 make sure the external load is reliableThe accurate ratio of the moment of inertia is set in the 2 parameter3, adjust the gain parameters, mainly the speed loop differential gain and the speed loop integral constant (through servo debugging monitoring software)Some servos have the ability to automatically infer gain parameters, but they can't handle everything.
The gain characteristic is not adjusted properly.
The mediation gain matches the load to solve the problem
