We have about 25 of these on site. Knowledgebase states that the Safe FLT S01 is caused by the failures of BF1 fuse on the Control board. The Drive will safely shut down and display Fault S01. The fault is not resettable, the PowerFlex 527 control module 25C-CTM1 must be replaced. - Nobody is willing to repair. Are there any known causes for this fault? Is this a common issue? The bus fuse is a surface mount fuse rated for about 350mA. We are thinking of replacing with a higher rated fuse. Has anybody done this? [/INST] If it's surface-mounted, replacing it on your own is going to void ANY sort of guarantee as to safety function. Should you have a safety incident, Rockwell will fight any lawsuit and likely be successful. Can you describe the installation and wiring? Your failures seem extremely uncommon. \\n </s>
