A4A9 Cooling Drive module temperature is
excessive.
Check ambient temperature. If it exceeds
40 °C/104 °F (IP21 frames R4
…R9) or if
it exceeds 50 °C /122 °F (IP21 frames
R0
…R9), ensure that load current does
not exceed derated load capacity of
drive. For all P55 frames, check the
derating temperatures. See chapter
Technical data, section Derating in the
Hardware manual of the drive.
Check drive module cooling air flow and
fan operation.
Check inside of cabinet and heatsink of
drive module for dust pick-up. Clean
whenever necessary.
A4B0 Excess temperature Power unit module
temperature is excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
A4B1 Excess temperature
difference
High temperature difference
between the IGBTs of different
phases.
Check the motor cabling.
Check cooling of drive module(s).
A4F6 IGBT temperature Drive IGBT temperature is
excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
A580 PU communication Communication errors
detected between the drive
control unit and the power unit.
Check the connections between the drive
control unit and the power unit.
Check the value of parameter 95.04
Control board supply.
A582 Auxiliary fan missing An auxiliary cooling fan
(connected to the fan
connectors on the control
board) is stuck or
disconnected.
Check the auxiliary code.
Check auxiliary fan(s) and connection(s).
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 (page 392).
0001 Auxiliary fan 1 missing.
0002 Auxiliary fan 2 missing.
A5A0 Safe torque off
Programmable warning:
31.22 STO indication
run/stop
Safe torque off function is
active, ie safety circuit signal(s)
connected to connector STO is
lost.
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
(page 245).
Check the value of parameter 95.04
Control board supply.
A5EA Measurement circuit

Problem with internal
temperature measurement of
the drive.
Contact your local ABB representative.
A5EB PU board powerfail Power unit power supply
failure.
