Servo system is a feedback control system used to accurately follow or reproduce a certain process. The servo system is an automatic control system that enables the output controlled quantity of the object's position, orientation, and state to follow the arbitrary change of the input target or given value. Its main task is to amplify, transform and adjust the power according to the requirements of the control command, so that the torque, speed and position control of the drive device output is very flexible and convenient.
The Fanuc servo drive is a part of the servo system and is used to control the fanuc servo motor. Its function is similar to that of a frequency converter acting on an ordinary AC motor. It is mainly used in high-precision positioning systems. Generally, the Fanuc ac servo motor is controlled by three methods of position, speed and torque to achieve high-precision transmission system positioning. It is currently a high-end product of transmission technology.
Choosing a suitable Mitsubishi servo drive needs to consider all aspects, which are mainly selected according to the requirements of the system. Before selecting the model, first analyze the following system requirements, such as size, power supply, power, control mode, etc., and set the direction for the model selection . Let's take a look at the various parameters of the fanuc DC servo drive, including continuous current, peak current, power supply voltage, control part power supply voltage, supported motor type, feedback type, control mode, the form of receiving commands, communication protocol and digital IO
Based on this information, we can roughly select the fanuc power servo drive that matches the fanuc motor. In addition, pay attention to the working environment, temperature and humidity, and whether the size of the installation is appropriate.
The choice of the Mitsubishi driver is not only to consider whether the drive is matched with the motor, but also to consider the control method. The Mitsubishi original servo drive has three control modes, including position, speed, and torque mode. Torque mode and speed can be set through external analog input or communication commands. The position mode is to determine the speed and length of motion by the frequency and number of pulses. In the torque mode, the motor outputs a fixed torque, which cannot control the position and speed. Position mode has very strict control over speed and position, and is generally used for positioning devices. We can select the appropriate control method according to the needs of the system and the type of upper control.
Nowadays, fanuc motor servo drives are becoming more and more intelligent. They not only support various types of servo motors, but are also compatible with multiple types of feedback. They can receive analog, PWM, pulse + direction and software commands. The communication supports CANopen, Ethercat and many others. Servo drive provides three-loop control and reversing functions in smart one-key tuning. It is very convenient to use and has high control accuracy, which greatly improves the performance of the system and saves a lot of time for developers.
