A. It does not affect the motor’s performance B. It limits the speed at which the motor can operate C. It limits the torque the motor can produce D. It increases the power consumption of the motor
Explanation: A VFD’s input voltage range defines the range of voltage that the VFD can accept as input. A VFD with a wider input voltage range can operate with a larger range of input voltages, while a VFD with a narrower input voltage range can only operate within a limited range of input voltages. If the input voltage is too low, the VFD may not be able to produce the desired frequency and voltage to drive the motor at the desired speed. This can limit the speed at which the motor can operate and affect its performance.
