    Tips: Servo motor application case

    In the operational process, robot realizes free movement through drives of servo motor. Thus, higher requirements on speed and accuracy of action of robot are actually higher requirements on response speed and controlling accuracy of servo motor.

    However, in actual operation of robot, servo motor is often in the state of various acceleration and deceleration, and positive and negative shift, which proposes high demands on short-term overload capacity, applicable range of inertia, band width of frequency response and response time of speed/torque.

    One important index is band width of frequency response which decides response speed of the servo system to orders, thus it is an important index for robot designers.
