Hello experts Frequently I and my colleges have questions from general knowledge to specific terms or more complicated technical details, or just finding the right solution, but sometimes is not easy to find it out appropriate answers, or complete technical solutions or knowledge to daily challenges. This topic is arised from EMC and motors retrofitting with drives, and common problems, incorrect installations or just lack of knowledge, and maybe can be extended to many other topics. Even exists manuals on how to install drives, shields, earthing, etc. for Sinamics or Micromaster or other manuals like the "ABC of motors" or "ABC of drives" frequently there are not global solution documents or documents that enters deeper into some application. I mean. In case of installing a drive with an old motor, what kind of filtering is necessary (common mode, DuDt, SinCos...) what precautions must be taken into account (motor isolation, bearings, earthing, etc.) and why this may cause problems. Other explicative documents like how to calculate installation overall performance efficiency, how disturbances can influence on consumption or overheating, etc. would be interesting (from strictly technical point of view, not comercial) to refresh or upgrade school/university studies. Some other manufacturers have some documents explaining that details (Danfoss), or even videos (good ones from KEB for instance) Take it as a sample on what I mean, when I say that's interesting, and what would be a pleasure to see from Siemens. As this topics can be really complicated to understand (cable capacitances, frequency domains, etc) or just sometimes is difficult to take into account all details or product solution, would be interesting to have such documents and/or videos to easy look at and improve overall technical knowledge of humans begins, or at least the ones that we frequently visit this forum. Just a thought... |
