Fault tracing
275
2009 DEVICE
OVERTEMP
(4210)
0308 bit 8
Drive IGBT temperature is
excessive. Alarm limit is
120°C. Check ambient conditions. See also section Derating on
page 291 .
Check air flow and fan operation.
Check motor power against unit power.
2010 MOTOR TEMP
(4310)
0305 bit 9
(programmable fault
function
3005 ... 3009 / 3503 )
Motor temperature is too
high (or appears to be too
high) due to excessive
load, insufficient motor
power, inadequate cooling
or incorrect start-up data. Check motor ratings, load and cooling.
Check start-up data.
Check fault function parameters.
Measured motor
temperature has exceeded
alarm limit set by
parameter
3503 ALARM
LIMIT.
Check value of alarm limit.
Check that actual number of sensors corresponds to value
set by parameter (
3501 SENSOR TYPE).
Let motor cool down. Ensure proper motor cooling: Check
cooling fan, clean cooling surfaces, etc.
2011 UNDERLOAD
(FF6A)
0308 bit 10
(programmable fault
function
3013 ... 3015 )
Motor load is too low due to
e.g. release mechanism in
driven equipment. Check for problem in driven equipment.
Check fault function parameters.
Check motor power against unit power.
2012 MOTOR STALL
(7121)
0308 bit 11
(programmable fault
function
3010 ... 3012 )
Motor is operating in stall
region due to e.g.
excessive load or
insufficient motor power. Check motor load and drive ratings.
Check fault function parameters.
2013 AUTORESET
0308 bit 12
Automatic reset alarm Check parameter group 31 AUTOMATIC RESET settings.
2018 PID SLEEP
0309 bit 1
Sleep function has entered
sleeping mode. See parameter groups 40 PROCESS PID SET
1 .. . 41 PROCESS PID SET 2 .
2019 ID RUN
0309 bit 2
Motor Identification Run is
on. This alarm belongs to normal start-up procedure. Wait until
drive indicates that motor identification is completed.
2021 START ENABLE 1
MISSING
0309 bit 4
No Start Enable 1 signal
received Check parameter 1608 START ENABLE 1settings.
Check digital input connections.
Check fieldbus communication settings.
2022 START ENABLE 2
MISSING
0309 bit 5
No Start Enable 2 signal
received Check parameter 1609 START ENABLE 2 settings.
Check digital input connections.
Check fieldbus communication settings.
2023 EMERGENCY
STOP
0309 bit 6
Drive has received
emergency stop command
and ramps to stop
according to ramp time
defined by parameter
2208
EMER DEC TIME.
Check that it is safe to continue operation.
Return emergency stop push button to normal position.
