Working principle
Signal reception and conversion: The controller receives command signals from external systems, such as signals from PLC, motion controllers and other equipment, and converts them into control signals required by the motor. These control signals determine the running direction of the servo motor. Speed, position and other parameters.
Power amplification: The power amplifier amplifies the weak current signal output by the controller to provide sufficient power to drive the servo motor, so that the motor can output corresponding torque and speed to drive the load movement.
Feedback and adjustment: The servo motor's own encoder will monitor the motor's motion status, such as position, speed and other information, in real time, and send these feedback signals back to the driver. The driver compares the feedback value with the target value and adjusts the output signal according to the deviation value to ensure the accuracy and stability of the motor's movement.
