POINTER ERROR Source selection (pointer) parameter points to
non existing parameter index.
(FFD0)
->POWEROFF! Inverter type (for example, sr0025_3) has been
changed. Inverter type is usually changed at
(FF39)
factory or during drive implementation.
PP OVERLOAD Excessive IGBT junction to case temperature.
This can be caused by excessive load at low
(5482)
frequencies (for example, fast direction change
3.18 AW 5 bit 5
with excessive load and inertia).
REPLACE FAN Running time of inverter cooling fan has
exceeded its estimated life time.

WHAT TO DO
Informative alarm
Check parameter 20.11 P MOTORING LIM
and 20.12 P GENERATING LIM settings.
Check Fault Function parameters.
Informative alarm
Check parameter 20.13 MIN TORQ SEL and
20.14 MAX TORQ SEL settings.
Check Fault Function parameters.
If LIMIT WORD 1 bit 0 TORQ MOTOR LIM
is 1,
- check motor parameter settings (parameter
group 99 START-UP DATA)
- ensure that ID run has been completed
successfully.
Check panel connection (see appropriate
hardware manual).
Check control panel connector.
Replace control panel in mounting platform.
Check Fault Function parameters.
Check source selection (pointer) parameter
settings.
Switch control board power off to validate
inverter type change.
Increase ramp time.
Reduce load.
Replace fan.
Reset fan run time counter 01.44.
Run the motor in the opposite direction and
deactivate the Slowdown signal. Or let the
drive run in the limited speed reference.
Run the motor in the opposite direction and
deactivate the Slowdown signal. Or let the
drive run in the limited speed reference.
Check start inhibit circuit (AGPS board).
