Why does the voltage on Digital Multimeter read higher than the actual output voltage on the Altivar VFD?

Article available in these languages: Тайский

Issue:
Digital Multimeter reads higher voltage in the output voltage from the Altivar VFD than the actual voltage.

Product Line:
ATV12, ATV312, ATV630, ATV930, S-Flex, E-Flex, Altivar Drives

Environment:
All

Cause:
NA

Resolution:
Normally, a True-RMS Digital multimeter (DMM) will read about 20 to 30% higher output voltage than what the actual Output voltage is. The reason is that a standard True-RMS DMM cannot reliably filter out the PWM(Pulse Width Modulation) output waveform and High Frequency noise from the VFD. A DMM with a Low Pass filter can fix this issue and can measure the output voltage more accurately.
