The servo system is an automatic control system that enables the output of the object's orientation, direction, and state to change with the arbitrary change of the input quantity (or given value). In the automatic control system, the system that can echo the control signal with a certain degree of accuracy is called the follow-up system, also known as the servo system. The main task of the servo is to expand, convert and control the power according to the requirements of the control command, so that the torque, speed and azimuth output of the driving equipment can be controlled very flexibly and conveniently.
The servo system is generally composed of three parts: a controller, a servo amplifier, and a servo motor. After the start of work, the power supply is transmitted to the servo motor through the servo amplifier, and the motor starts to work, and the encoder located at the tail of the servo motor at this moment feeds back the motor orientation information that collects to the servo amplifier, and the amplifier transmits to the controller, and the controller makes a judgment and announces the instruction information after getting this information, and controls the work and orientation of the servo motor.
The advantages of Mitsubishi servo system are as follows:
1. The servo motor stops in the regular direction according to the command announced by the control equipment, but due to inertia, the motor cannot be stopped instantaneously after the command is announced, there is a delay in time, and the machine will vibrate when the motor is working. In response to this delay and vibration, Mitsubishi Electric has developed advanced control skills, and the servo system is agile to stop and activate in a short period of time after the control equipment announces the command.
2. The control accuracy of Mitsubishi Electric's servo system is high, and the accuracy of the encoder can reach one millionth of a turn, which is at the leading level in the world.
3. At present, there are many manufacturers of servo motors in the world, but there are not many manufacturers who can supply controllers, servo amplifiers, inverters and other series of equipment at the same time.
