    Tips: Three loop control of servo motor

    Normally servo is three loop control. "Three loop" means three closed loop negative feedback PID adjusting system.

    1. The most inner PID loop is electrical current loop. This loop completely operates inside servo driver, through hall device to inspect each phase output current from driver to motor, negative feedback makes PID adjustment for current set up, then output current would get close or equal to set up current value. Current loop controls motor torque, therefore, under torque mode, driver calculation amount is the minimum, dynamic response is the fastest.
    2. The second loop is speed loop, through checking motor coder signal to make negative feedback PID adjustment, its inner loop PID output is current loop set up, therefore, speed loop control including speed loop and current loop. In other words, any mode must use current loop, current loop is the base of control. While under speed control and position control, system is also making current (torque) control, in order to achieve relative control for speed and position.
    3. The third loop is position loop, it’s the most outside loop. It can be built between driver and motor coder, or built between exterior controller and motor coder or final loading, this should be up to actual condition. As position control loop inside output is speed loop set up, under position control mode, system makes calculation for all 3 loops, at the time system has the maximum calculation amount, dynamic response speed is the slowest.
