Why does the ATV58 drive with Ethernet card trip on CNF communication fault when Timeout is set other than ZERO and I/O Scanning is set to NO.
All with Ethernet card
To prevent the timeout, the drive`s word 400 must be continuously written to in less than 15 second increments, repeatedly.
In essence, every ``good`` write to W400 resets the drive`s internal timeout timer. If the timer times out, the drive trips on a CNF error.
Additionally, check the connection of the communication network to the drive controller because may be loose or improperly connected, therefore not communicating.
