(HTML)55A3122-20-9/96CS2275 application field and working principleThe 55A3122-20-9/96CS2275 is a servo amplifier developed for servo motors. It is mainly used to control the speed and torque of rotation in servo motors, and its application field is very wide. It can be used in industrial automation, robots, medical devices, automotive, aerospace, semiconductor production and other industrial fields.The 55A3122-20-9/96CS2275 servo amplifier uses a special vector control loop to control the speed and torque of the motor. It has a set of dedicated hardware design for vector control, and the system loop is divided into two parts: speed loop and torque loop.In the speed loop, the motor speed is determined by a set of voltage and current PID control. The voltage is firstly rectified and filtered, then it is adjusted to a set of desired speed control current, which is compared with the actual speed measured from the motor with feedback. After comparison, a corrected speed control signal is obtained at the PID output, then it is added to the speed setting value by an adder. Commanded speed control is output through PWM conversion.In the torque loop, the torque also depends on voltage and current PID control. The voltage is rectified and filtered, and compared with the actual torque detected by a current sensor, and then a corrected torque control signal is obtained at the PID output. This signal is added to the torque setting value by an adder, and then the commanded torque control is output from the PWM conversion.The above is the application field and working principle of 55A3122-20-9/96CS2275 servo amplifier. It is a universal servo amplifier with high performance, high accuracy, strong interference resistance, wide operating temperature range and long service life. Its vector control algorithm can effectively reduce torque ripple, ensure high-precision motion control accuracy and high-efficiency torque control performance, which makes it more suitable for servo control in a variety of harsh environment.
