CanworldCDE500 frequency converter applies on the numerical control machine tool
1 Overview
CNC machine tools are integrated electromechanical products integrating mechanical, electrical, hydraulic, pneumatic, microelectronics, and information technologies. They are flexible, versatile, highly accurate, and highly efficient "flexible" automation in machinery manufacturing equipment. Production equipment, it will be a variety of operations and procedures required for the processing process and the shape and size of the workpiece, using digital code, through the control medium into the numerical control device, the numerical control device to process and calculate the input information, command and control the machine system and drive components , Automatically machine the required workpieces. This article mainly introduces the unique performance and superior cost performance of the Canworld CDE500 vector converter on CNC machine tools, as well as the successful application on CNC machine tools.
2 CanworldCDE500 inverter application in CNC machine tools
CanworldCDE500 series inverter adopts advanced speed-less vector control technology, the motor has large torque at low speed, 150% torque output when the operating frequency is 0.5Hz, and high speed accuracy, complete functions, and can automatically detect the dynamic operation of the motor. The parameters are adjusted accordingly to ensure that the motor operates at the highest efficiency. Therefore, the speedless vector inverter can replace the AC servo system and 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.

The AI1/GND terminal of the inverter provides the analog value with the numerical control system speed, AI1 is connected to the positive analog signal of the numerical control system interface, and GND is connected to the negative signal. The inverter operating parameters are as follows:
3 advantages of CanworldCDE500 inverter in CNC machine tools
CanworldCDE500 inverter can fully meet the requirements of the spindle control of the machine tool. The output torque at low-speed operation is stable, which can meet the processing needs of different parts. The structure is simple and compact, and real stepless speed regulation can be realized. The speed of this spindle is controlled by an external analog signal to control the output frequency. Different machining processes (such as roughing, finishing, etc.) require different rotation speeds. At this time, the digital control system can output different analog voltage signals to the inverter. Different speeds are achieved, and at the same time the start-stop signal is also controlled by the numerical control system, which improves the degree of automation, prolongs the service life of the tools, changes the situation in the past that relied on imported products, greatly reduced the operating costs of the company, and brought good results to the enterprise. Economic benefits.
