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.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
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).
5080 Fan Cooling fan feedback missing. See A581 Fan (page 342).
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.
