When starting a CNC lathe, the motor current can be 5-6 times higher than the rated current, which not only affects the motor's lifespan but also consumes a significant amount of electricity.
While the system design includes a certain margin in motor selection and the motor speed is fixed, actual operation sometimes requires lower or higher speeds. Therefore, frequency converter retrofitting is essential.
Frequency converters can achieve soft starting of the motor, achieve energy-saving speed regulation by changing the frequency of the equipment's input voltage, and provide overcurrent, overvoltage, and overload protection functions.
