10. Diagnostics

10. 6. Communication fault

BACnet communication faults are indicated by the red ERR LED on the BACnet card.

In the factory default configuration, a communication time-out fault will trigger a resettable [Com. network] (CnF) drive fault and initiate a

freewheel stop.

It is possible to change the response of the drive in the event of a BACnet communication fault (see the Configuration section).

- [Com. network] (CnF) drive fault (freewheel stop, stop on ramp, fast stop or DC injection braking stop)

- No drive fault (stop, maintain, fallback)

The Parameters Manual contains a detailed description of how to manage communication faults (see the "Communication monitoring"

section).

• Following initialization (power-up), the drive checks that at least one command or reference parameter has been written for the first time

by BACnet.

• Then, if a communication fault occurs on BACnet, the drive will react according to the configuration (fault, maintain, fallback, etc.).

10. 7. Card fault

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

- Hardware fault on the BACnet card

- Dialog fault between the BACnet card and the drive

The response of the drive in the event of an [internal com. link] (ILF) fault cannot be configured, and the drive trips with a freewheel stop.

This fault cannot be reset.

Two diagnostic parameters can be used to obtain more detailed information about 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 on top of option card no. 1)

The BACnet card can be in position 1 or 2.

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

the [1.10 DIAGNOSTICS] (DGt-) menu, [MORE FAULT INFO] (AFI-) submenu.
