Cause
A cooling fan has reached the end of
its estimated lifetime.
See parameters 5.41 and 5.42.
Fault in external device 1.
Fault in external device 2.
Fault in external device 3.
Fault in external device 4.
Fault in external device 5.
DDCS (fiber optic) communication
between converters (for example, the
inverter unit and the supply unit) is
lost.
Note that the inverter unit will
continue operating based on the
status information that was last
received from the other converter.
The supply unit (or other converter)
has generated a warning.
The drive is entering sleep mode.
The speed controller autotune routine
did not complete successfully.
The drive was stopped before the
autotune routine finished.
The drive was started but was not
ready to follow the autotune
command.

What to do
Check the auxiliary code. The code
indicates which fan is to be replaced.
0: Main cooling fan
1: Auxiliary cooling fan
2: Auxiliary cooling fan 2
3: Cabinet cooling fan
4: PCB compartment fan
Refer to the hardware manual of the
drive for fan replacement instructions.
Check the external device.
Check setting of parameter
External event 1 source.
Check the external device.
Check setting of parameter
External event 2 source.
Check the external device.
Check setting of parameter
External event 3 source.
Check the external device.
Check setting of parameter
External event 4 source.
Check the external device.
Check setting of parameter
External event 5 source.
Check status of other converter
(parameters 6.36 LSU Status Word and
6.39 Internal state machine LSU CW ).
Check settings of parameter group
DDCS communication. Check the
corresponding settings in the control
program of the other converter.
Check cable connections. If necessary,
replace cables.
The auxiliary code specifies the
original warning code in the supply
unit control program. See section
Auxiliary codes for line-side converter
warnings (page 697).
Informative warning. See section
Process PID control, and parameters
40.41...40.48.
Check the auxiliary code (format XXXX
YYYY). "YYYY" indicates the problem
(see actions for each code below).
Repeat autotune until successful.
Make sure the prerequisites of the
autotune run are fulfilled. See
section Speed controller
autotune (page 87).
