Fault tracing
285
MOT POW LIM
(FF86)
3.18 AW 5 bit 12
(programmable
Fault Function
30.23 )
Drive limits motor power according to limits
defined with parameters
20.11 and 20.12 .
Informative alarm
Check parameter
20.11 P MOTORING LIM
and 20.12 P GENERATING LIM settings.
Check Fault Function parameters.
MOT TORQ LIM
(FF85)
3.18 AW 5 bit 11
(programmable
Fault Function
30.23 )
Drive limits motor torque according to
calculated motor pull-out torque limit and
minimum and maximum torque limits defined
with parameters
20.13 and 20.14 .
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.
PANEL LOSS
(5300)
3.09 AW 2 bit 13
(programmable
Fault Function
30.02 )
Control panel selected as active control
location for drive has ceased communicating. Check panel connection (see appropriate
hardware manual).
Check control panel connector.
Replace control panel in mounting platform.
Check Fault Function parameters.
POINTER ERROR
(FFD0) Source selection (pointer) parameter points to
non existing parameter index. Check source selection (pointer) parameter
settings.
->POWEROFF!
(FF39) Inverter type (for example, sr0025_3) has been
changed. Inverter type is usually changed at
factory or during drive implementation. Switch control board power off to validate
inverter type change.
PP OVERLOAD
(5482)
3.18 AW 5 bit 5
Excessive IGBT junction to case temperature.
This can be caused by excessive load at low
frequencies (for example, fast direction change
with excessive load and inertia). Increase ramp time.
Reduce load.
REPLACE FAN
(4280)
3.18 AW 5 bit 0
Running time of inverter cooling fan has
exceeded its estimated life time. Replace fan.
Reset fan run time counter
01.44 .
SLOW DOWN UP
(FFF4) Slowdown signal 10.09 activated in the Up
direction
Run the motor in the opposite direction and
deactivate the Slowdown signal. Or let the
drive run in the limited speed reference.
SLOW DOWN
DOWN
(FFF5) Slowdown signal 10.09 activated in the down
direction
Run the motor in the opposite direction and
deactivate the Slowdown signal. Or let the
drive run in the limited speed reference.
START INHIBI
(FF7A)
AW 1 bit 0
Optional start inhibit hardware logic is
activated. Check start inhibit circuit (AGPS board).
