XFC 3phase VFDs Advantages


Superior performance

a.High-precision motor parameter self-learning function
The VFD can identify motor-related parameters through dynamic or stationary self-learning, and the identified parameters can be used for vector control without speed sensor to obtain better control accuracy and dynamic response.
Dynamic self-learning 
—— It is necessary to disconnect the load to identify the motor parameters with higher accuracy and to obtain better control performance
Static self-learning 
—— Suitable for occasions where the load cannot be disconnected.

b. High performance vector control

c. Highly efficient over-voltage and over-current stall control, reducing the number of failures
Over-voltage stall 
—— During operation, the output frequency of the controller is adjusted through the bus voltage feedback to suppress the rise of the bus and prevent its over-voltage protection 
Over-current protection 
——During operation, adjust the output frequency of the controller through the magnitude of the feedback current, so that the current is controlled within the set range;
Wave-by-wave current limiting
——Under extreme operating conditions such as sudden load (locked rotor), sudden increase in current DC braking, etc. to prevent excessive output current, the controller detects the current of each sampling cycle to precisely control the power device switching to avoid over-current failure.

d. Powerful instantaneous power failure protection function
When the grid power supply is abnormal, the motor can decelerate and stop normally. On the one hand, part of the energy can be fed back to the bus through deceleration, so that the voltage can be stabilized in the working state for a longer time. On the other hand, when the grid returns to normal power supply, the motor can start immediately, and will not stop freely due to a sudden under-voltage fault when the grid power supply is abnormal. In a large inertia system, it takes a long time for the motor to stop freely. When the grid After the power supply is normal, since the motor is still rotating at high speed, starting the motor at this time can easily cause overload or over-current faults to the converter.

High reliability design
