The application of frequency converters in the CNC lathe industry

System configuration
· Control methods: loss control without speed sensor, vector control with speed sensor, VF control.
· Control objects: speed control and torque control.
· PID algorithm: Advanced PID algorithm with fast response and strong adaptability.
· Frequency range: 0-300Hz, an outstanding representative of high-performance and multifunctional frequency converters.
· Frequency source combination: There are rich frequency source stacking and switching methods, suitable for synchronous control.

 
Technological requirements
· Ensure normal cutting operation at low rotational speeds.
· The low-speed 0.5Hz torque reaches 180% torque and runs smoothly.
· The acceleration and deceleration time is 0.1 seconds, with fast response speed and no voltage or overcurrent protection skipped.
· The spindle speed accuracy is within 0.02%.
· The spindle achieves lower noise during operation.
· Equipped with an external braking resistor, DC braking can be implemented for quick parking.
