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.COMPowerFlex 700 变频器硬件结构PowerFlex 700 Drive OverviewProcessor and I/OPowerFlex 700 DriveControl PanelComputerMotorEncoder(optional) PowerFlex 700 Replacement Policy Frames 0 - 4: These frames are considered remove and replace due to their very smal
2、l 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 have a desire to
3、 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, current transformers,
4、 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 due to improper
5、torquing or application of thermal grease. All kits will include repair instruction including torque values as required.
