As part of the PLC motion control system, the main functions of the servo drive include:
1. Receive motion control signals from PLC and convert them into corresponding motor control signals;
2. Control the rotation direction and speed of the motor to achieve precise position control;
3. Provide feedback signal to PLC so that it can monitor the position and speed of the motor;
4. With various protection measures, such as overload protection, overspeed protection, overvoltage protection, etc., to ensure the safe operation of the motor.
In summary, servo drives play a key role in PLC motion control systems, which achieve precise control and protection of motors by receiving, converting, controlling and feedback signals.
