Cause
An auxiliary cooling fan
(connected to the fan
connectors on the control unit)
is stuck or disconnected.
Safe torque off function is
active, i.e. safety circuit
signal(s) connected to
connector XSTO is lost.
Problem with internal
temperature measurement of
the drive.
Power unit power supply
failure.
Communication errors
detected between the drive
control unit and the power unit.
Problem with measurement
circuit of power unit (analog to
digital converter)
Problem with current or voltage
measurement of power unit
State feedback from output
phases does not match control
signals.
Charging in progress
Adequate motor control at
requested output frequency
cannot be reached because of
limited switching frequency
(e.g. by parameter 95.15).
The flash memory (in the
memory unit) has been erased
too frequently, compromising
the lifetime of the memory.
What to do
The auxiliary code identifies the fan (1:
Auxiliary fan 1, 2: Auxiliary fan 2).
Check auxiliary fan(s) and connection(s).
Replace faulty fan.
Make sure the front cover of the drive
module 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 (page 591).
Check safety circuit connections. For
more information, see appropriate drive
hardware manual and description of
parameter 31.22 STO indication run/stop
(page 306).
Check the auxiliary code (format XXXY
YYZZ). "Y YY" specifies through which
BCU control unit channel the fault was
received ("0 00" with a ZCU control unit).
"ZZ" specifies the location (1: U-phase
IGBT, 2: V-phase IGBT, 3: W-phase
IGBT, 4: Power unit INT board, 5: Brake
chopper, 6: Air inlet, 7: Power supply
board, 8: du/dt filter, FAh: Air in temp).
Contact your local ABB representative.
Check the connections between the drive
control unit and the power unit.

Informative warning. Wait until charging
finishes before starting the inverter unit.
Informative warning.
Avoid forcing unnecessary parameter
saves by parameter 96.07
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.
