10. Fault tracing
When the option board or the AC drive control diagnostics
detect an unusual operating condition, the drive opens a
notification, for example, on the keypad. The keypad shows
the ordinal number of the fault, the fault code and a short
fault description.
You can reset the fault with the Reset button on the
control keypad, via the I/O terminal or via the used fieldbus
protocol. The faults are stored in the Fault history menu,
which can be browsed. The fault table presents only the
fault conditions related to the fieldbus in use.

When you contact a distributor or a factory because of
a fault condition, always write down all the texts and
codes on the keypad display. Then send the problem
description together with the Drive Info File to the
following address: [email protected].
If possible, also send a “Wireshark” log from the
situation if applicable.
