Application Of CNC Lathe Inverter

When the CNC lathe starts, the current of the motor will be 5-6 times higher than the rating, which will not only affect the service life of the motor but also consume more electricity. The system will leave a certain margin in the motor selection when designing, and the speed of the motor is fixed, but in the actual use process, sometimes it is necessary to run at a lower or higher speed, so it is very necessary to carry out frequency conversion transformation. The frequency converter can realize the soft start of the motor, achieve the purpose of energy-saving speed regulation by changing the input voltage frequency of the equipment, and can provide the equipment with overcurrent, overvoltage, overload and other protection functions.
