Hello Experts, We had a F243 fault on our drive, we reset the power and this cleared the fault and tested this as functional again. However Upon checking the fault history in Drivemonitor under general diagnostics. We found F082 occurred before the F243 fault. Are we correct to suspect F082 occurred and as a consequence F243 appeared on the drive as a fault. Continued to look at the fault history and F243 showed link internal with a fault code of '2', fault time; 0017:0023:2337. The fault history also showed F082 as a TB/CB telegram failure with a fault code of '1', fault time; 0017:0023:1375. I removed the CUVC card, Rev G, checked firmware of the CUVC as v3.4 and it has a simolink board (top), and a comm board (bot) connected to it. checked through the connections and found all OK, nothing out the ordinary. Checked profibus connections at the connector and terminals and found all OK and shielding is good. When i opened up the Diagnostic information on the fault it read: "F082 - TB/CB telegram failure Cause: No new process data have been received by the TB/CB within the telegram failure time. Remedy: Fault value r949 1= TB/CB 2-additional CB -Check connection to TB/CB Check P722 (CB/TB TlgOFF) Replace CB or TB" From this information, I also increased P722 from 10ms to 20ms and also ordered simolink and comm boards assuming that is what the CB/TB is referring too. Assuming F082 is the cause of F243 to appear due to the timing, as the diagnostic information explaining F243 as, "Fault in internal linking. Once of the two linked partners does not reply" I found this internal linking fault is a not a very broad description of the problem. Could F082's description of the fault explaining the TB/CB issue could be the root cause of this...? We are yet to carry out functional testing on the drive with P722 changed from 10ms to 20ms and would appreciate any further advice. Thanks in advance. ------------------------------------------------------------------------------------------ |
