Issue:
What is the CFA fault code on the ATV630 or ATV930 Process drives?

Product Line:
ATV630 or ATV930

Environment:
All

Cause:
The monitoring function has detected an error on the digital input assigned to [CabinetCircuit A Assign].
CFA is active when the detected error duration is longer than [CabinetCircuit A Delay] FdA.

Resolution:

The fault can only appear if a cabinet input has been configured as Cabinet Circuit A error. The stop type when the fault appears is configurable. The acquisition time of LI is 2ms. Probable cause: The monitoring function has detected an error on the digital input assigned to [CabinetCircuit A Assign]. CFA is active when the detected error duration is longer than [CabinetCircuit A Delay] FdA. Remedies: • Check the connected device (door switch, thermal switch,…) and its wiring. • Check the parameters CFAA (high/low assignment of the cabinet IO)
