Could this be part of the issue? chapter 7 harmonics bouncing back from the caps in the rotary phase converter perhaps? so maybe a filter... real early here so only partially awake
John When the requirements regarding system fault level are observed and when using the appropriate line supply filters, the harmonics fed back into the line supply lie below the compatibility level of Class 3 of the electromagnetic environment of industrial plants and systems according to EN61000–2–4:2002. When the recommended SIEMENS line filter is used and the EMC mounting/ installation regulations are complied with, the noise emission limits according to EN50081–2 Electromagnetic Compatibility (EMC) – Generic Standard, Noise Immunity/emission – Part 2: Industrial environments (1993) are complied with. Notice If line filters are used that SIEMENS has not certified for use with SIMODRIVE 6SN11xx/6SLxx, this can result in harmonics being fed back into the line supply. These harmonics can damage/disturb other equipment connected to this line supply. Certification, e.g. CE is invalid. Certificates from Siemens are invalid, for example CE , UL. You are responsible for generating/obtaining the certificates for this new combination. It is not permissible to connect additional loads after the line filter On 5/25/2012 2:59 PM, andy pugh wrote: > On 25 May 2012 20:17, John Thornton<bjt...@gmail.com> wrote: > >> The infeed unit is a 6SN1145-1BA00-0BA0 > This looks like the manual. > http://support.automation.siemens.com/WW/llisapi.dll/csfetch/59401543/PJU_0212_en.pdf?func=cslib.csFetch&nodeid=60683460&forcedownload=true > > There is an interesting section about how to connect to various > earthing styles.
