PV70L16-8PY is a kind of variable frequency high-voltage AC drive. It is a full-digital speed-adjustment cabinet drive, designed according to the laws of mechanical and electrical engineering for the operation control of single-phase or three-phase asynchronous motor.

Application field

PV70L16-8PY can be widely used to control the following machines, such as textiles, chemical fiber, plastics, printing, woodworking, paper, winery, light industry machinery, water conservancy and hydropower, environmental protection and other industries machinery.

For example, the application of PV70L16-8PY in paper manufacturing industry can save energy. Through AC frequency conversion technology, the energy consumption of the equipment such as paper machine, dryer, calender, sizing machine, winder, etc. can be reduced, and the production process can be optimized and improved.

In view of the above application fields, PV70L16-8PY is an essential product for energy saving and emission reduction in the current industrial production.

Working Principle

The working principle of PV70L16-8PY is based on the “V/f” working mode, that is, the input voltage is converted to the output motor frequency is fixed, the output motor voltage is sensed by vector control, the output motor real-time said state information to the controller, through the motor model and the grid compensation process, the controller according to the set parameters to compensate for the external grid power, keep the output torque and speed accuracy.

At the same time, PV70L16-8PY provides full or precise speed regulation, and the speed can be set accurately and achieved in a wide range; with over-voltage, under-voltage, overload, phase loss and other protection functions.

In addition, PV70L16-8PY has the advantages of small size, light weight, user-friendly programming, automatic adaptation of the motor parameters to ensure the safe and reliable operation of the motor under the condition of speed regulation.

Conclusion

PV70L16-8PY is a kind of variable frequency high-voltage AC drive with wide application field, which can be used in the paper manufacturing, textile, plastics, printing, woodworking and other industries. The working principle of PV70L16-8PY is based on the “V/f” working mode. In addition, it has the advantages of small size, light weight, user-friendly programming, automatic adaptation of the motor parameters to ensure the safe and reliable operation of the motor under the condition of speed regulation.
