The application of INVT-CHV series inverters in the papermaking industry and its steady speed performance prove that the INVT-CHV has a PG vector (closed loop vector) frequency conversion speed regulation scheme that can meet the various requirements in the papermaking process. Requirements such as speed setting, speed fine adjustment, acceleration/deceleration control, speed/torque switching, load sharing, and winding control can all be solved.
INVT-CHV series high-performance vector inverters provide a perfect solution for papermaking machinery, reducing energy consumption, increasing production efficiency and saving users more cost.
The INVT CHV series of high-performance inverters will be used more and more widely in the paper industry.
The frequency converter has been successfully applied to papermaking machinery
INVT-CHV inverters from INVT are successfully used in many paper mills in Tianjin. Because the INVT-CHV frequency converter has the characteristics of large starting torque, strong overload capability, fast dynamic response and high speed precision, it can fully meet the requirements of its production process and greatly improve the economic benefits of the enterprise.
