Servo motor encoder What is the role of the encoder

1. Servo motor encoder has the following functions

1. It can remember the magnetic pole position of the motor, and the servo drive can best control the servo motor according to the magnetic pole position.

2. Do speed closed loop and position closed loop to achieve precise speed regulation and precise position control.

Two: The servo motor has its own encoder. You can use the PLC to send pulses to control the distance of the servo by converting the servo electronic gear ratio. The setting method refers to the description of the electronic gear setting of the servo controller.

Position control is generally positioning control, which completes the desired displacement by receiving pulse commands and in accordance with the set electronic gear ratio.

Speed control generally controls the speed of the servo motor by receiving analog signals to achieve better follow-up.

The servo system has three closed-loop controls, from the outside to the inside, the position loop, the speed loop, and the current loop.

All three loops are used in position control.

Only the speed loop and current loop are used in speed control.
