There are three control methods for servo motors: position control, speed control, and torque control. What is used here is position control.
Before position control, it is necessary to set the parameters of the servo motor. For example, after calculation, it is found that 1000 pulses are required for the servo motor to rotate once and move forward by 10cm. Then, connect the PLC and servo drive. The working position that needs to be reached by the servo motor is 25cm, so 2500 pulses are sent to the servo driver through the PLC. After the PLC sends out the pulses, it continues to send 1000 pulses, and the motor reaches 35cm. This positioning is relative motion positioning. Servo has two positioning methods: relative motion and absolute motion.
