Phenomenon: When the program is running, the motor itself will emit an electric current sound. As the voltage increases (12V, 24V, 48V, 110V, 600V), the current sound increases.
The customer speculates that the phenomenon is caused by the Fast estimator (estimating the position of the motor rotor) and needs to be closed. The simultaneous opening of the Motion controller and Fast estimator resulted in the program writing the switches for the controller and estimator, without separate control
Summary: What the customer needs is an interface to find the estimator switch in the program, or parameters to eliminate sound
