What is INF29 on ATV980.

INF29 is MCE Power brick internal error.
It is due to Interrupted communication between the CMP6 (Power board) and the CMI1 (Inverter
brick) and CPLD internal communication interruption.

If the drive has the failure randomly than it may be an issue with the control wire.  Via SoMove service Section, they can indicate which wire (Connections) is impacted, and then they need to change this particular wire.
In most of the case, the wire is not fixed (not in a good position inside the plug)

it is recommended to change the power board and one Inverter board (the one which is detected by somove- service section) mostly the inverter board on the brick is impacted.
