Frequently Asked Questions
What are the main benefits of using these VFDs?
The primary benefits include significant energy savings, precise motor speed control, and reduced mechanical stress on equipment through controlled acceleration.
How do VFDs control motor speed?
They control the speed of an AC motor by varying the frequency and voltage of the power supplied to the motor.
What kind of communication protocols are supported?
Our drives utilize the internationally standard MODBUS-RTU protocol, making them easy to integrate with PLC systems and HMI touch screens.
Can the drive handle momentary power failures?
Yes, the unit features an intelligent "instant stop without stopping" function that uses energy fed back from the load to maintain operation during brief voltage drops.
What protection features are built into the unit?
The drive includes comprehensive protection for input/output phase loss, overcurrent, overvoltage, undervoltage, overheating, and motor overload.
Is the output frequency adjustable for high-speed motors?
Yes, under V/F control, the output frequency can range from 0 up to 3000Hz, suitable for specialized high-speed industrial applications.
