3HAC14550-404B servo controller, also known as servo driver or servo amplifier, is a controller used to control servo motors. Its function is similar to the control of ordinary AC motors by frequency converters, and it is a part of servo systems, mainly used in high-precision positioning systems. Servo controllers generally control servo motors through three methods: position, speed, and torque, achieving high-precision positioning of the transmission system. They are high-end products in transmission technology. Servo controllers are an important component of modern motion control and are widely used in automation equipment such as industrial robots and CNC machining centers. Especially the servo controller applied to control AC permanent magnet synchronous motors has become a hot research topic both domestically and internationally. The current design of AC servo controllers generally adopts a closed-loop control algorithm based on vector control for current, speed, and position. Among them, the speed closed-loop design plays a crucial role in the entire servo control system, especially in the performance of speed control. In the speed closed-loop of the servo controller, the real-time speed measurement accuracy of the motor rotor is crucial for improving the dynamic and static characteristics of speed control in the speed loop. The working principle of the 3HAC14550-404B servo controller is that its core main control board receives control signals and transmits drive signals and detection signals. Through the relay board, it completes dual closed-loop control, including speed regulation and current regulation, to achieve speed control and commutation control of the motor. The driver board of the driver receives signals from the main control board, drives the power conversion circuit, and realizes the normal operation of the motor. The servo controller in the servo control system is equivalent to the brain, responsible for regulating the speed of the electric motor, so it is also an automatic speed adjustment system.
