An auxiliary cooling fan
(IP55 internal fan) is
stuck or disconnected.
Check the auxiliary code.
Check the auxiliary fan and
connection.
Replace faulty fan.
Make sure the front cover of the drive
is in place and tightened. If the
commissioning of the drive requires
that the cover is off, this warning will
be generated even if the
corresponding fault is defeated. See
A5A0 Safe torque off
Programmable warning:

A682
Flash erase speed
exceeded
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
96.07
or 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 value
The motor parameters
are set incorrectly.
Check the auxiliary code. See actions
for each code below.
The drive is not
dimensioned correctly.
