Cause : TB/CB telegram failure comes when no new process data have been received by the TB or the CB within the telegram failure time.
A "TB/CB telegram failure" fault F082 in Siemens Masterdrive indicates an issue with communication between the drive and an optional board.
- Check the connections of the CB/TB.
- Check P695 “CB/TB TLG-fail“.
- Replace CB.
- Replace TB.
