Warning / Aux. code
An auxiliary cooling fan
(IP55 internal fan) is
stuck or disconnected.
Safe torque off function
is active, ie safety
circuit signal(s)
connected to connector
STO is lost.
Problem with internal
temperature
measurement of the
drive.
Power unit power
supply failure.
Measurement circuit
fault.
Measurement circuit
fault.
State feedback from
output phases does not
match control signals.
Charging feedback
signal missing.
The flash memory (in
the memory unit) has
been erased too
frequently,
compromising the
lifetime of the memory.
The motor parameters
are set incorrectly.
The drive is not
dimensioned correctly.
Cause What to do
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
fault
5081 Auxiliary fan broken on
page 73.
Check safety circuit connections. For
more information, chapter The Safe
torque off function in the Hardware
manual of the drive and description of
parameter 31.22 STO indication run/
stop in the Firmware manual.
Check the value of parameter 95.04
Control board supply.

Check the feedback signal coming
from the charging system.
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.
Check the auxiliary code. See actions
for each code below.
