CNC machine tools are integrated electromechanical products integrating mechanical, electrical, hydraulic, pneumatic, microelectronics, and information technologies for over 30 years. They are flexible, versatile, highly accurate, and highly efficient in machinery manufacturing equipment. "Flexible" automated production equipment, which will require various operations and steps of the machining process and the shape and size of the workpiece. It will be sent to the numerical control device through the control medium with a digital code. The numerical control device will process and calculate the input information, and the command will control the machine tool system. With the drive element, the required workpiece is automatically machined. The level of technological level of CNC machine tools and their percentage in the production and total ownership of metal cutting machine tools are one of the important indicators of a country’s national economic development and the overall level of industrial manufacturing. In recent years, the share of CNC machine tools in China's enterprises has increased year by year. There have been more use in large and medium-sized enterprises, and they have also been commonly used in small and medium-sized enterprises and even individual enterprises.
2. Introducing the characteristics of Komron's non-induction vector inverter
KV2000 series inverter adopts advanced speed sensorless vector control technology. The motor has large torque at low speed and zero servo function. The running frequency is 100% torque output at 0Hz, and the speed accuracy is high, the price is reasonable, and the function is complete. , Can automatically detect the parameters of the motor's dynamic operation and make adjustments to ensure that the motor runs in the most efficient state, therefore, no speed sensor vector inverter can replace the AC servo system, is the best choice for the machine tool industry. Because of the high cost performance of the frequency converter for the customer, the use of the frequency converter on lathes is very common. 
2) The control mode is speedless feedback vector control, and the control performance is greatly improved compared with the previous VF control mode, especially in the low speed torque to meet the needs of the machine tool spindle, the starting torque can reach more than 150% at 0.5HZ ;
3) carrier frequency range 0 ~ 16.9KHz, to ensure that the motor runs quietly;
4) Power range 0.75kw ~ 500kw, output frequency range 0.0 ~ 650.0Hz, suitable for high speed CNC machine tool applications;
5) Provide a standard 0 ~ 10V analog interface (input impedance 300Kohm), compatible with most CNC system interface, strong versatility;
