Direct torque control/vector control is adopted in the special frequency conversion control system. PVD special frequency converter has the characteristics of high efficiency, superior electromagnetic compatibility and strong environmental adaptability, so as to effectively reduce the interference to the power grid and surrounding equipment and fully meet the requirements of various working conditions.
Special frequency converter type selection
1. Voltage matching
Select the same power supply voltage grade as the motor. PVD special inverter has three voltage grades: 380V, 660V and 1140V.
2. Power matching
The power of frequency converter is 1.12 times of motor power
Note: the frequency converter is designed for the working condition of the belt conveyor, meeting the requirements of 1.5 times overload of 1min/10min and 2 times overload of 10s/10min.
3. Energy feedback (optional)
PVD dedicated inverter as normal (two) as the limit and energy feedback type (four quadrant), usually choose ordinary, do not need to indicate, in a condition with energy feedback (such as the working condition of belt conveyor by), should choose energy feedback type inverter.
