2、 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 repair larger frame drives rather than s

3、end 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, fan transformers and power devices just

4、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 torquing or application of thermal grease

5、. All kits will include repair instruction including torque values as required.
