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).

4982
External temperature
2
(Editable message text)
Measured temperature 2 has
exceeded fault limit.
Check the value of parameter
Check the cooling of the motor (or other
equipment whose temperature is being
measured).

4990
FPTC not found
A thermistor protection module
has been activated by
parameter
detected.
Power down the control unit and make
sure that the module is properly inserted
in the correct slot.
The last digit of the auxiliary code
identifies the slot.
4991
Safe motor
temperature 1
(Editable message text)
The thermistor protection
module installed in slot 1
indicates overtemperature.
Check the cooling of the motor.
Check the motor load and drive ratings.
Check the wiring of the temperature
sensor. Repair wiring if faulty.
Measure the resistance of the sensor.
Replace sensor if faulty.
4992
Safe motor
temperature 2
(Editable message text)
The thermistor protection
module installed in slot 2
indicates overtemperature.
4993
Safe motor
temperature 3
(Editable message text)
The thermistor protection
module installed in slot 3
indicates overtemperature.

Fan
Programmable fault:
Cooling fan feedback missing.

5081
Auxiliary fan not
running
Programmable fault:
An auxiliary cooling fan
(connected to the fan
connectors on the control unit)
is stuck or disconnected.
See
(page
).

STO hardware failure
Safe torque off hardware
failure.
Contact your local ABB representative,
quoting the auxiliary code. The code
contains location information, especially
with parallel-connected inverter modules.
When converted into a 32-bit binary
number, the bits of the code indicate the
following:
31…28: Number of faulty inverter module
(0…11 decimal). 1111: STO_ACT states
of control unit and inverter modules in
conflict
27: STO_ACT state of inverter modules
26: STO_ACT state of control unit
25: STO1 of control unit
24: STO2 of control unit
23…12: STO1 of inverter modules 12…1
(Bits of non-existing modules set to 1)
11…0: STO2 of inverter modules 12…1
(Bits of non-existing modules set to 1)
