A8BF ULC underload
warning
Programmable fault:
37.04 ULC underload
actions
Selected signal has fallen
below the user underload
curve.
Check for any operating conditions
decreasing the monitored signal (for
example, loss of load if the torque or
current is being monitored).
Check the definition of the load curve
(parameter group 37 User load curve).
A8C0 Fan service counter A cooling fan has reached the
end of its estimated lifetime.
See parameters 05.41 and
05.42.
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.

AF80 INU-LSU comm loss
Programmable warning:
60.79 INU-LSU comm loss
function
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.
Check status of other converter
(parameters 06.36 and 06.39).
Check settings of parameter group 60
DDCS communication. Check the
corresponding settings in the control
program of the other converter.
Check cable connections. If necessary,
replace cables.
