We have four Sinamics G20X VFD converters,[snip] G120X Another question: This unit is designed for 400VAC 3-phase. But to form the DC link capacitors requires 100VAC, 200VAC, 300VAC, and 400VAC. I'm not sure we have 3-phase power available at these voltages. Is it possible to use 1-phase power to form these capacitors? ------------------------------------------------------------------------------------------ |

Hello tjrob; Ths document might provide the answer you are looking for, especially the section shwn in the attached screenshot: MICROMASTER, SINAMICS V20/G110/G120/G120C/G120P: Forming the DC link capacitors. https://support.industry.siemens.com/cs/se/en/view/1960441 Hope this helps; Daniel Chartier |
