Delta C2000 Inverter Successfully Applied in Core Process of Metallurgical Industry
As a world-class steel country, the metallurgical industry is one of the most important traditional pillar industries in China. As the structural adjustment of steel products is undergoing fruitful acceleration, metallurgical automation has also played an increasingly important role. Due to historical reasons, the frequency converters used in the metallurgical industry are mostly international brands supporting equipment. In recent years, domestic products have gradually stepped in, but they are mainly applied to auxiliary equipment such as fans and pumps.
Recently, the world's leading industrial automation brand Delta Electronics Co., Ltd., for the high-end magnetic field vector control universal C2000 series inverter for high-end application market demand, with its high-speed, pulse positioning, dual rated load and other functions and good dynamic response performance The rapid acceleration and deceleration characteristics and high cost performance have been successfully applied to the roller control of a rolling mill, which has improved the reliability and stability of the equipment and has been recognized by customers.
At present, the roller drive is basically driven by a single inverter to run multiple motors. Each motor directly drives a single roller. The difficulty of variable frequency speed regulation lies in that the same set of roller tables is driven by a single inverter. Taiwan motor performance can not be completely consistent, coupled with different degrees of work roll wear, will result in the same set of motor load is inconsistent, resulting in light load motor terminal voltage may exceed the rated value, resulting in deterioration of the motor insulation, in particular, will result in exchange The magnetic circuit of the motor is saturated; the roller motor is generally far away from the speed control device, and the cable is very long. However, the on-site environment is rather harsh, and the high temperature and humidity cause the insulation of the cable and the motor to decrease. In addition, the output voltage of the inverter is a PWM waveform. When impedances at both ends of the cable do not match, traveling wave reflection occurs, and the motor peak voltage at the motor terminal also deteriorates the insulation of the motor and the cable.
The C2000 series adopts magnetic field-oriented vector control. It can not only control the speed but also serve as servo position control. At the same time, the position control can achieve point-to-point positioning and unique dynamic response performance, which can well meet the above control requirements. In addition, C2000 series inverters also have the following performance advantages:
Excellent speed/torque/position control mode, dual rated design (ND general load/HD heavy load);
Excellent four-quadrant torque control and torque limit;
Induction motor and synchronous motor control double machine;
Built-in Delta PLC function, safe parking function, braking unit;
Drive system networking;
Synchronous positioning control function;
Long life design and life detection of important parts;
Enhanced environmental tolerance and protection;
Global Safety Compatible with CE/UL/CUL;
Modular design is easy to maintain and expand;
High-speed communication interface and built-in CANopen and MODBUS and optional PROFIBUS-DP, DeviceNet, MODBUS TCP, EtherNet/IP Cards.
With the continuous improvement of the degree of automation, inverter transformation technology will be widely used in the various processes of the metallurgical industry, whether it is energy-saving or technological transformation, frequency control technology has played an increasingly important role. The outstanding performance of the C2000 inverter in the metallurgical industry is deeply loved by users. With more and more applications in the market, the C2000 inverter will have more room for development.
