Cause : Default parameters have been loaded comes when the EEPROM Fail 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 given below:

1 The most significant digit of the internal parameter database version number has changed.
2 The CRCs 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 The internal I/O hardware has changed.
7 The position feedback interface hardware has changed.
8 The control board hardware has changed.
9 The checksum on the non-parameter area of the EEPROM has failed.
