does anyone know what I am talking about? This is a 2000 Clubcar DS 48v.
Is it telling the controller how much current the motor is using and does this limit the current going to the motor from the controller?

It might communicate with the controller to provide information about the current being drawn by the motor. This data could be utilized by the controller to regulate or manage the power being delivered to the motor, ensuring it stays within safe operating limits or providing feedback for certain functionalities. However, without more specific details or visuals, it's a bit like solving a riddle without the whole story.
