Carving in the industrial field is the most widely used mold industry, the production process in the mold carving is not the main processing methods and means of production, but its role is minimal, in general, is a "finishing touch", which is carved objects " graphics, text, and complex surfaces "characteristics of the decision.

Home and abroad have applied to the inverter manufacturer of inverter products on CNC machine tools, CNC machine tools on the drive in the application of the basic requirements are: low torque, output stable; high-performance vector control; torque fast dynamic response, steady speed high accuracy; deceleration stopping speed; anti-jamming; but according to market research shows part of the brand of inverter products in use for some time easily lead to CNC machine tools motor damage.

In fact, the frequency converter application in laser engraving machine is nothing new, and is currently the most widely used on the carving is CNC laser engraving machine, laser engraving machine spindle speed generally in the 0-24000 rev / min, carving processing to improve accuracy, is carving equipment needed to solve the major problems. Sine Electric Company in the sum of the current mainstream of the various brands of laser engraving machine inverter products, based on independent research and development used in CNC laser engraving machine on the high-performance converter products - EM320A series vector frequency products. It is reported that large quantities of the products have been used in various types of CNC machine tools.

Recently, sinusoidal electrical engineers to the product of a CNC Equipment Co., Ltd. Zhejiang, its produced laser engraving machine for on-site commissioning, confirmed EM320A series vector frequency in CNC laser engraving machine to show good operational performance. Debugging data from the field with a clear advantage reflects EM320A: random noise carrier fine motor function, weak magnetic curve of the motor function of temperature rise is small; wiring, simple operation, just set the debug analog frequency corresponds to the maximum you can boot to normal work! Motor parameters automatically recognized, dynamic identification of motor parameters, to ensure system stability and accuracy; speed range of 0.0 ~ 1000.0Hz CNC laser engraving machine fully meets the high requirements. Automatically track changes in the load and automatically limit the output current, it does not exceed the maximum allowable current value. Even if the mutation load, rapid acceleration and deceleration, the inverter does not occur over-current, short circuit fault, the drive configuration to achieve the EM320A series of high-performance, high reliability; fast response and stable shutdown speed; drive and the motor with the power to use, no need to enlarge the capacity of the inverter.
