2008 PANEL LOSS
0308 bit 7
(programmable fault
function 3002)
Control panel selected
as active control
location for drive has
ceased
communicating.
Check panel connection.
Check fault function parameters.
Check control panel connector.
Refit control panel in mounting
platform.
If drive is in external control mode
(REM) and is set to accept start/stop,
direction commands or references
through control panel:
Check group 10 START/STOP/DIR
and 11 REFERENCE SELECT
settings.
2009 DEVICE
OVERTEMP
0308 bit 8
Drive IGBT
temperature is
excessive. Alarm limit
is 120 °C.
Check ambient conditions. See also
section Derating on page 359.
Check air flow and fan operation.
Check motor power against drive
power.
2010 MOTOR TEMP
0308 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
0308 bit 10
(programmable fault
function
3013…3015)
Motor load is too low
due to eg release
mechanism in driven
equipment.
Check for problem in driven
equipment.
Check fault function parameters.
Check motor power against drive
power.
2012 MOTOR STALL
0308 bit 11
(programmable fault
function
3010…3012)
Motor is operating in
stall region due to eg
excessive load or
insufficient motor
power.
Check motor load and drive ratings.
Check fault function parameters.

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.
