How does a VFD’s energy-saving function work?
A. By adjusting the voltage and frequency of the power supplied to the motor to match the load demand
B. By turning off the motor when it is not in use
C. By adjusting the load on the motor to match the power demand
D. By using a lower voltage and frequency when the motor is running at low speeds
Answer:A

Explanation: A VFD’s energy-saving function works by adjusting the voltage and frequency of the power supplied to the motor to match the load demand. When the load on the motor is low, the VFD reduces the voltage and frequency, which reduces the power consumption of the motor. This can result in significant energy savings, especially when the motor is running at low speeds or when the load on the motor is variable.
