Cause
Drive module temperature is
excessive.
Drive IGBT temperature is
excessive.
Power unit module
temperature is excessive.
High temperature difference
between the IGBTs of different
phases.
Measured temperature 1 has
exceeded fault limit.
Measured temperature 2 has
exceeded fault limit.
Cooling fan feedback missing.
An auxiliary cooling fan
(connected to the fan
connectors on the control unit)
is stuck or disconnected.
0001 Auxiliary fan 1 broken.

What to do
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.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
Check the motor cabling.
Check cooling of drive module(s).
Check the value of parameter
Measured temperature 1.
Check the cooling of the motor (or
other equipment whose temperature
is being measured).
Check the value of parameter
Measured temperature 2.
Check the cooling of the motor (or
other equipment whose temperature
is being measured).
See A581 Fan (page 342).
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
or by cycling power.
