AULT 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.
NOTE! 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 local distributor. See local contacts: www.danfoss.com. If possible, also send a
fieldbus communication log from the situation if applicable.
