What component positions the load according to the input from the servo amplifier?

The servo motor is the key component responsible for positioning the load based on the input it receives from the servo amplifier. In a servo control system, the servo amplifier takes the desired position or command input and modifies it to drive the servo motor. The motor then moves the load to the specified position with precision.

The servo motor operates by converting electrical energy into mechanical energy, allowing it to produce controlled motion. It utilizes feedback from connected devices to adjust its position continually. By doing so, it ensures that the load reaches and maintains the target position dictated by the servo amplifier. This functionality is essential for applications requiring high accuracy and response rates, such as robotics, CNC machinery, and various automation systems.

In contrast, the controller manages the overall system and defines the commands, the feedback device provides information about the actual position back to the system for corrections, and the signal converter handles the transformation of signals but does not perform the physical positioning of the load.
