The servo system is an automatic control system that makes the output of the object's position, direction, and condition change according to 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 accuracy is called the follow-up system, also known as the servo system. The main task of the servo is to amplify, convert and control the power according to the requirements of the control command, so that the torque, speed and position output by the drive device can be controlled very flexibly and conveniently.
The Mitsubishi servo system is generally composed of three parts: a controller, a servo amplifier, and a servo motor. After the start of operation, 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 collected motor position information 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 position of the servo motor.
The advantages of Mitsubishi servo system are as follows:
1. The servo motor stops at the specified position according to the command announced by the control device, but due to inertia, the motor cannot be stopped instantaneously after the command is announced, there is a delay in the moment, and the machine will oscillate when the motor works. In response to this delay and oscillation, Mitsubishi Electric has developed advanced control skills, and the servo system quickly stops and starts up quickly within a short period of time after the control device 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, although there are many manufacturers of servo motors in the world, there are not many manufacturers who can supply controllers, servo amplifiers, inverters and other series of equipment together.
