Trip
dr.CF Drive configuration
The hardware ID does not match the user software ID.
Sub-trip
232
Recommended actions:
• Hardware fault – Contact the supplier of the drive
EEF Default parameters have been loaded
The EEF trip indicates that default parameters have been loaded. The exact cause/reason of the trip can be identified from
the sub-trip number.
Sub-trip
31
The drive holds two banks of user save parameters and two banks of power down save parameters in non-volatile memory.
If the last bank of either set of parameters that was saved is corrupted a U.S or Pd.S trip is produced. If one of these trips
occurs the parameters values that were last saved successfully are used. It can take some time to save parameters when
requested by the user and if the power is removed from the drive during this process it is possible to corrupt the data in the
non-volatile memory.
If both banks of user save parameters or both banks of power down save parameters are corrupted or one of the other
conditions given in the table above occurs EEF.xxx trip is produced. If this trip occurs it is not possible to use the data that
has been saved previously, and so the drive will be loaded with default parameters. The trip can only be reset if Parameter
mm.000 (mm.000) is set to 10, 11, 1233 or 1244 or if Load Defaults (11.043) is set to a non-zero value.
Recommended actions:
• Default the drive and perform a reset
• Allow sufficient time to perform a save before the supply to the drive is removed
• If the trip persists - return drive to supplier
Et An External trip is initiated
An Et trip has occurred. The cause of the trip can be identified from the sub trip number displayed after the trip string. See
table below. An external trip can also be initiated by writing a value of 6 in Pr 10.038.
Sub-trip
6
Recommended actions:
• Check the value of Pr 10.032.
• Select 'dest' (or enter 12001) in Pr mm.000 and check for a parameter controlling Pr 10.032.
• Ensure Pr 10.032 or Pr 10.038 (= 6) is not being controlled by serial comms
FAn.F Fan fail
This trip cannot be reset until 10s after the trip was initiated.

Check that the fan is fitted and connected correctly.
Check that the fan is not obstructed.
Contact the supplier of the drive to replace the fan.
