,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 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 变频器 报警判断及清除,Alarms,一类报警: 只显示一种状态，不会引起变频器停车。 可通过参数259 Alarm Config 1更改设置 二类报警: 阻止操作者在未正确设置之前启动变频器。 不能通过参数更改设置 永远使能,二种类型的报警:,Alarms,一类报警引起黄色状态灯常亮:,Status LED,Alarms,二类报警引起黄色状态灯闪烁:,Status LED,Alarms,报警也会在HIM上显示报警图标：,Alarm Icon,Common Drive Alarms,Digital input alarms Stop asserted alarms,Digital Input Drive Alarms,因数字输入功能定义有冲突引起的报警 三种类型: Dig In ConflictA，数字输入功能冲突 Dig In ConflictB，配置启动输入，未配置停止。或其他功能冲突。 Dig In ConflictC，不止一个物理输入被配置成相同的输入功能。,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.
