4290 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.
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.
See A4B0 Excess temperature (page
390).
4380 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 35.02
Measured temperature 1.
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 35.03
Measured temperature 2.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
5081 Auxiliary fan broken An auxiliary cooling fan
(connected to the fan
connectors on the control unit)
is stuck or disconnected.
Check the auxiliary code.
Check auxiliary fan(s) and connection(s).
Replace fan if faulty.
Make sure the front cover of the drive is
in place and tightened.
If the commissioning of the drive requires
th the cover is off, activate parameter
31.36 Aux fan fault bybass within 2 min
from control unit reboot to temporarily
suppress the fault.
Reboot the control unit (using parameter
96.08 Control board boot) or by cycling
power.
0001 Auxiliary fan 1 broken.
0002 Auxiliary fan 2 broken.
5090 STO hardware failure STO hardware diagnostics has
detected hardware failure.
