Application of Laeg LD320 series inverter in CNC engraving machine

I. Overview of CNC engraving machine

CNC engraving machine has been widely used in various industries, especially in woodworking, stone, advertising and so on. And the CNC engraving machine

The spindle system of CNC engraving machine is an important component, which has a very important influence on its performance. Frequency converter as spindle system

The heart of the system is an indispensable key component.

Second, the characteristics of CNC engraving machine using site

The fluctuation range of power grid is large;

2.2 There are more processing dust, oil pollution and fog, and the environment is relatively bad;

2.3 Low frequency requires large torque and normal cutting force;

2.4 Spindle speed is high, and high speed stability accuracy is required at high speed;

2.5 acceleration and deceleration time as short as possible.

Third, the application scheme of Shenzhen Laeg inverter CNC engraving machine

LD320 series inverter adopts the new DSP chip of TI company, supplemented by optimized vector control technology, which can achieve high torque at low frequency.

With high speed stability and precision, it is the optimal choice for CNC engraving machine tools.

3.1 wide range voltage use design, 310V~460V;

3.2 Thickened three-proof paint technology has strong adaptability to harsh environments such as metal dust and corrosive gases;

3.3 Optimized vector control technology, low frequency and high torque output, high speed stabilization accuracy and short acceleration and deceleration time;

3.4 VF control is selected as the control mode, simple PLC is built in the frequency converter, and 16-step speed control can realize multi-functional logic control.

So as to meet that requirement of various complex working condition.
