Cause : Default parameters have been loaded comes when 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 & Reason

1 The most significant digit of the internal parameter database version number has changed
2 The CRC's applied to the parameter data stored in internal non-volatile memory indicate that a valid set of parameters cannot be loaded
3 The drive mode restored from internal non-volatile memory is outside the allowed range for the product or the derivative image does not allow the previous drive mode
4 The drive derivative image has changed
5 The power stage hardware has changed
6 Reserved
7 Reserved
8 The control board hardware has changed
9 The checksum on the non-parameter area of the EEPROM has failed.
