A682 Flash erase speed The flash memory (in the
memory unit) has been
erased too frequently,
compromising the
lifetime of the memory.
Avoid forcing unnecessary
parameter saves by parameter
cyclic parameter writes (such as
user logger
triggering through parameters).
Check the auxiliary code (format
XYYY
YZZZ). “X” specifies the source
of
warning (1: generic flash erase
supervision). “ZZZ” specifies the
flash
subsector number that
generated the
warning.
A6A4 Motor nominal

The motor parameters
are set incorrectly.
Check the auxiliary code. See
