Diagnostics

Card fault

The [internal com. link] (ILF) fault appears when serious problems arise:

- Hardware fault in the Controller Inside card

- Dialog fault between the Controller Inside card and the drive

The drive behavior cannot be configured when an [internal com. link] (ILF) fault occurs, and the drive trips with freewheel stopping. This

fault cannot be reset.

Two diagnostic parameters can be used to obtain more detailed information on the origin of the [internal com. link] (ILF) fault:

- [Internal link fault 1] (ILF1) if the fault has occurred on option card no. 1 (installed directly on the drive).

- [Internal link fault 2] (ILF2) if the fault has occurred on option card no. 2 (installed directly on the drive).

The Controller Inside card can be in position 1 or in position 2.

Parameters [Internal link fault 1] (ILF1) and [Internal link fault 2] (ILF2) can only be accessed on the graphic display terminal, in the [1.10

DIAGNOSTICS] (DGT-), [MORE FAULT INFO] (AFI-) menu.
