4110
Control board
temperature
Control board temperature is
too high.
Check proper cooling of the drive.
Check the auxiliary cooling fan.
4210
IGBT overtemperature Estimated 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.
4290
Cooling
Drive module temperature is
excessive.
Check ambient temperature. If it exceeds
50 °C /122 °F, ensure that load current
does not exceed derated load capacity of
drive. 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.
42F1
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.
4310
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.
4180
Excess temperature
difference
High temperature difference
between the IGBTs of different
phases.
Check the motor cabling.
Check cooling of drive module(s).
4981
External temperature
1
(Editable message text)
Measured temperature 1 has
exceeded fault limit.
Check the value of parameter
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check the value of parameter
.
5090
STO hardware failure
STO hardware diagnostics has
detected hardware failure.
Contact your local ABB representative for
hardware replacement.
5091
Safe torque off
Programmable fault:
Safe torque off function is
active, ie. safety circuit
signal(s) connected to
connector STO is broken
during start or run.
Check safety circuit connections. For
more information, see chapter
The Safe
torque off function
in the hardware
manual of the drive and description of
parameter
(page
).
5092
PU logic error
Power unit memory has
cleared.
Contact your local ABB representative.
5093
Rating ID mismatch
The hardware of the drive does
not match the information
stored in the memory. This
may occur eg. after a firmware
update.
Cycle the power to the drive. You may
have to be repeat this.
5094
Measurement circuit

Problem with internal
temperature measurement of
the drive.
Contact your local ABB representative.
