"Screw is positioned over the goods and an implementation, the principle is the rotary motion into linear motion, but also capable of linear motion into rotary motion. Screw is generally used in precision machinery, a higher accuracy , can be converted into linear motion to rotational motion, it is conducive to improve production efficiency and the yield of [1] the role of the main inverter frequency power into different frequency electric-power control means, mainly by means of power semiconductor devices. frequency having the main function of the VVVF AC induction motor, to enhance the precision operation. current mainstream control method to achieve high-precision control is threaded through the servo controller controls the servo motor servo drive servo primarily controlling a motor, which, in the main part of the servo drive system is similar may be by a touch screen input parameters, and by PLC communication, to effect control of the inverter and servo drives. the design different motors to control the positioning screw .

"The screw is an ideal product for positioning, the principle is to convert the swing motion into a straight motion, but also to convert the straight movement into a swing motion. The screw is generally used in precision machinery, has a high precision, can turn the rotation movement into a straight line motion, is conducive to the improvement of production efficiency and pass rate. The function of the inverter is mainly to convert the frequency power supply into a different frequency of electrical control devices, mainly with the help of electric semiconductor devices. The functions of the inverter mainly include the variable frequency speed of AC asynchronous motor, improve the operating accuracy and so on. At present, the mainstream control method of the market is to control the servo motor through the servo controller to achieve the high-precision control of the screw. Servo drivers are mainly used for the control of servo motors, which are part of the servo system, mainly similar to the inverter. The function of controlling the drive and the servo driver can be achieved by means of the touch screen input parameters and communication with the PLC. This design uses different motors to control the screw positioning.

"The lead screw is an ideal product for positioning. Its principle is to transform the rotary motion into linear motion, and it can also transform the linear motion into rotary motion. Generally speaking, the lead screw is used in precision machinery, with high precision. It can turn the rotary motion into linear motion, which is conducive to the improvement of production efficiency and qualification rate [1]. The function of frequency converter is to change the power frequency power supply into the power control device with different frequency, mainly with the help of power semiconductor devices. The functions of the frequency converter mainly include the frequency conversion and speed regulation of the AC asynchronous motor, the improvement of the operation accuracy, etc. At present, the main control method in the market is to control the servo motor through the servo controller to achieve high-precision control of the lead screw. Servo driver is mainly used for servo motor control, which is a part of servo system, mainly similar to frequency converter. It can input parameters through touch screen and communicate with PLC to control inverter and servo driver. This design uses different motors to control the lead screw positioning.
