A plant engineer is reviewing a VFD parameter sheet. The drive's carrier frequency is set to 12 kHz instead of the default 4 kHz. What is the most likely trade-off?
-
A
Lower audible motor noise but increased drive heat generation and derating required
-
B
Higher torque output at low speeds with no derating penalty
-
C
Reduced harmonic distortion on the input power line
-
D
Improved motor efficiency at full load
