Table 13-2 Fault Messages (Alphabetical by Keypad Text)
Fault Fault # Cause What to do
Excess temperature 4310 Power unit module
temperature is excessive.
Check ambient conditions.
Check air ow and fan operation.
Check heatsink ns for dust pick-up.
Check motor power against drive power.
Excess temperature
difference
4380 High temperature
difference
between the IGBTs of
different phases.
Check the motor cabling.
Check cooling of drive module(s).
External
temperature
1
(Editable message text)
4981 Measured temperature 1
has exceeded fault limit.
Check the value of parameter 35.02 Measured
temperature 1.
Check the cooling of the motor (or other equipment whose
temperature is being measured).
Check the value of parameter 35.12 Temperature 1 fault
limit.
External
temperature
2
(Editable message text)
4982 Measured temperature 2
has exceeded fault limit.
Check the value of parameter 35.03 Measured
temperature 2.
Check the cooling of the motor (or other equipment whose
temperature is being measured).
Check the value of parameter 35.22 Temperature 2 fault
limit.
Fan 5080 Cooling fan stuck or
disconnected.
Check fan operation and connection. Replace fan if faulty.
Auxiliary fan broken 5081 An auxiliary cooling fan
(connected to the fan
connectors on the
control unit) is stuck or
disconnected.
Check auxiliary fan(s) and connection(s). Replace fan if
faulty. Reboot the control unit (using parameter 96.08
Control board boot) or by cycling power.
STO hardware
failure
5090 Safe torque off hardware
failure.
Contact your local ABB representative.
Safe torque off
Programmable fault: 31.22
STO indication run/stop
5091 Safe torque off function is
active, i.e. safety circuit
signal(s) connected to
connector XSTO is broken
during start or run.
Check safe torque off circuit connections. For more
information, see appropriate drive hardware manual and
description of parameter 31.22 STO indication run/stop.
PU logic error 5092 Power unit memory has
cleared.
Cycle the power to the drive. If the control unit is
externally powered, also reboot the control unit (using
parameter 96.08 Control board boot) or by cycling its
power. If the problem persists, contact your local ABB
representative.
Rating ID mismatch 5093 The hardware of the
drive does not match the
information stored in the
memory unit. This
may occur eg. after
a rmware update or
memory unit replacement.
Cycle the power to the drive.
PU communication 5681 The way the control unit is
powered does not
correspond
to parameter setting.
Check setting of 95.04 Control board supply.
Communication errors
detected between the
drive control unit and the
power unit.
Check the connection between the control unit and the
power unit.
Power unit lost 5682 Connection between the
drive control unit and the
power unit is lost.
Check the connection between the control unit and the
power unit.
PU communication
internal
5690 Internal communication
error.
Contact your local ABB representative.
