Tuoda servo stepper motor is a closed-loop control of the position of a stepper motor. Needless to say, it must be a position loop, and the control quantity is length (displacement).
This is because the closed-loop control strategy of position control can be roughly divided into three types according to the control amount:
1. Position loop, which uses displacement to do closed loop control.
2. Speed ​​loop, is to use speed for closed loop control.
3. Acceleration loop, which uses acceleration for closed-loop control.
So the subject said position closed-loop control, I think it has become a position loop.
These three control strategies can realize the positioning control of Tuoda stepper motors. But the speed loop and acceleration loop can not only control the position, but also realize the speed and acceleration control of the stepper motor; and the speed loop and acceleration loop also have a definite control on the frequency response of the servo stepper motor, because the position loop cannot be accurate. Control the speed and acceleration of the servo stepper motor to reach the predetermined position, and the speed loop and acceleration loop can.
Therefore, the closed-loop control strategy should be selected according to the demand. Generally speaking, high-precision positioning control requires not only a position loop but also a combination of a speed loop and an acceleration loop.
As for you to use the motion board to control the stepper motor, this is normal. If you want to determine the control strategy, you have to look at the algorithm in the control board.
