For paper machine main drive applications, INVT adopts a PWM rectifier common DC bus multi-drive solution. Through precise speed and torque control, it ensures long-term reliable operation of the drive system from pulp processing to paper winding.
High energy consumption and high cost of the drive system
Poor system stability and equipment usability
Difficult system maintenance and high troubleshooting cost
By replacing international brand VFDs with INVT GD880 series engineering drive VFDs, we fully meet the functional and performance requirements of paper production lines and reduce costs for customers.
View Larger ImagePWM rectifier common DC bus multi-drive solution, low energy consumption and low harmonics.
Integrated master-slave control, torque and tension control, easy to debug.
Rectifier redundant design with complete protection functions and high system reliability.
The rectifier and VFD adopt a user-friendly modular design for easy maintenance. The system can resume operation within half an hour after module replacement.
High-precision speed control (approx. 0.2%) ensures stable production and consistent product quality.
Automatic power balance and distribution control (the system only controls the master unit, not the slave units) simplifies operation and improves equipment usability.
The VFD is equipped with a fully automatic power-on buffering function. Power can be switched off and on at any time, greatly facilitating operation for maintenance personnel.
With more than ten years of market validation and mature technology, the system features high stability in both software and hardware operation.
