,PowerFlex 700 變頻器調(diào)試與故障排除 山東省冶金設計院自動化公司 李剛 SDMLG001126.COM,PowerFlex 700 變頻器硬件結構,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 their 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 have 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, current 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 due to improper torquing or application of thermal grease. All kits will include repair instruction including torque values as required.,PowerFlex 700 Frame 5,PowerFlex 700 變頻器 報警判斷及清除,Alarms,一類報警: 只顯示一種狀態(tài)，不會引起變頻器停車。 可通過參數(shù)259 Alarm Config 1更改設置 二類報警: 阻止操作者在未正確設置之前啟動變頻器。 不能通過參數(shù)更改設置 永遠使能,二種類型的報警:,Alarms,一類報警引起黃色狀態(tài)燈常亮:,Status LED,Alarms,二類報警引起黃色狀態(tài)燈閃爍:,Status LED,Alarms,報警也會在HIM上顯示報警圖標：,Alarm Icon,Common Drive Alarms,Digital input alarms Stop asserted alarms,Digital Input Drive Alarms,因數(shù)字輸入功能定義有沖突引起的報警 三種類型: Dig In ConflictA，數(shù)字輸入功能沖突 Dig In ConflictB，配置啟動輸入，未配置停止?；蚱渌δ軟_突。 Dig In ConflictC，不止一個物理輸入被配置成相同的輸入功能。,Digital Input Drive Alarms,Digital Input Drive Alarms,Digital Input Drive Alarms,Forward/Reverse Speed Select 1 Speed Select 2 Speed Select 3 Run Forward Run Reverse Jog Forward Jog Reverse Run Stop Mode B Bus Regulation Mode B Acc2/Dec2 Accel 2 Decel 2,Dig In ConflictC：More than one physical input has been configured to the same input function.
