CNC machine tool is the abbreviation of computer numerical control machine tools. It is an automatic machine tool equipped with a program control system. The control system can logically process the program specified by the control code or other symbolic instructions, decode it, express it with coded numbers, and input it into the numerical control device through the information carrier. After the arithmetic processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. CNC machine tool solves the problem of complex, precise, small batch, and multi-variety parts processing. It is a flexible and efficient automatic machine tool. It represents the development direction of modern machine tool control technology and is a typical mechanical and electrical integration. Chemical products.
Application site process requirements:
1) Large torque at low frequency is required
At low frequency (1 ~ 10Hz), it can come out with a 150% rated torque.
2) Fast torque dynamic response speed and high precision of steady speed
It can achieve a very good dynamic response effect. According to the change of load, it responds quickly through the change of output torque, so as to achieve the stability of the shaft speed.
3) Fast deceleration and stopping speed
Generally, the acceleration and deceleration time of CNC machine tools are relatively short, the acceleration time is guaranteed by the performance of the inverter, and the deceleration time depends on the external braking resistor or braking unit.
4) High reliability
The inverter has a low failure rate, stable and reliable operation
Powtech PT300 series inverter output 180% torque at 0.5HZ, fast dynamic response, fully intelligent control system, powerful braking function, 0.5 seconds start and stop, V / F flux vector, high-speed accuracy, powerful overcurrent capability, Up to 210%, fully meet user needs.
