We have a winder(paper machine) application with a Siemens 6RA24 drive. On startup the drive is coming up with fault F04. We have eliminated the fault by decreasing the startup tension on the system from 7 to 3. Once the drive is able to crawl, we input the default tension(7) and therafter run the machine without any faults. We have basically found a quick-fix to eliminate the fault on startup and have not found the root cause. I have looked at previous threads by sammy_s and have played around with P086, P087 & P089 with any success.
Please assist with further suggestions.
