1、,PowerFlex 700 变频器调试与故障排除 山东省冶金设计院自动化公司 李刚 SDMLG001126.COM,PowerFlex 700 变频器硬件结构,PowerFlex 700 Drive Overview,Processor and I/O,PowerFlex 700 Drive,Control Panel,Computer,Motor,Encoder (optional),PowerFlex 700 Replacement Policy,Frames 0 - 4: These frames are considered “remove and replace“ due to t
2、heir very small size and the fact that it is far easier and more cost effective to repair them in a Rockwell repair facility than in the field. Simple parts like front covers, conduit plates, fans, brake resistors and cassettes will be the only items available as kits.,Frames 5 & 6: Some customers h
3、ave a desire to repair larger frame drives rather than send them to the factory for repair. To help facilitate field repair, we will offer more spare components along with the simpler components previously mentioned (fans, covers, etc.). These kits will include circuit board assemblies, MOVs, curren
4、t transformers, fan transformers and power devices just to name a few. For power devices, our team is working on the full heatsink as a replacement component for Frames 5 & 6 instead of individual IGBTs and other like components. This will make it a bit easier to repair in the field without errors d
