Inomax servo motion control inverter solution for metal cutting application

The steel plate slitting machine is a device for longitudinally slitting metal wide coil materials. It is used for slitting metal coil materials: such as strip steel, stainless steel, copper strip, aluminum foil, etc. Market operators, rolling mills, electrical industry, automobiles, stamping parts, etc.). Different from general shearing equipment, this equipment rolls the circular blade on the plate to complete a new type of infinitely long shearing action.
Slitting machine structure: It is composed of unwinding (unwinding), feeding positioning, slitting and slitting, curling (winding) and other equipment. Its main function is to cut the wide coil material into a narrow width and a certain size of coil material to prepare for other processing procedures in the future.
When metal slitting machine manufacturers design the slitting machine production line, they specially designed an integrated structural scheme, which can significantly improve the rigidity of the mechanical structure, reduce the degree of vibration, and help improve the quality of the finished product. However, this structure relies on the speed and torque control accuracy of the drive to the motor. Through the excellent speed and torque mode control of the high-performance drive, it not only improves the production efficiency, but also reduces the mechanical failure rate and maintenance cost.
Equipment such as unwinding (unwinding), slitting and slitting, coiling (winding), laminating and other equipment needs to be equipped with a motor and a driver. The feeding positioning and edge feeding machines need to be equipped with two motors and drivers, and each transmission part is driven by a servo motor.
8pcs Inomax ACS880 drives control the servo motors and communicate with PC through Profinet to realize speed and torque mode control.
The motor has been coupled with the machine during general debugging on site. Due to the large load rate and rotational inertia of the motor, the dynamic identification cannot achieve the effect of accurate identification. Inomax ACS880 driver can perform static identification on the basis of the motor stopping and not rotating, and accurately identify the characteristics of the motor data to build an accurate motor model. In order to let  drive perform direct torque control to achieve a better control effect.
Inomax ACS880 driver has superior performance and can control the servo motor to output high torque at low speed, meeting the requirements of different complex working conditions in different application sites. And communicate with PC by Profinet communication and exchange data in real time, which can ensure the stable and reliable operation of the overall system of the slitting machine. And when controlling the slitting machine, sanding line and laminating line with high tension requirements, the steel plate will be unrolled for tension control, The plate will naturally oscillate. In this environment, the driver increases the vibration suppression function in the torque mode. Even when the machine is running at very low speed, the state is still stable, and the plate has no vibration.
