Programmable, see 31.41 Main fan fault function
Drive cooling fan feedback at the DI is missing. See also 5080.
Check:
− The settings of 20.38 Drive fan acknowledge source and 20.40 Drive/Motor fan delay time.
− The drive fan operation and connection.
− The drive fan contactor.
− The drive fan circuit.
− The drive fan klixon.
− The drive fan components.
− The drive fan supply voltage.
− The drive fan direction of rotation.
− The drive door open.
− The drive cooling air inlet (e.g. filter).
− The drive cooling air outlet.
− H7 an H8 pressure switch (setting should be 2 mbar).
− The used digital inputs and outputs (groups 10 and 11).
