Drive IGBT
temperature is
excessive. Alarm limit
is 120 °C.
Check ambient conditions. See also
section Derating on page 386 .
Check air flow and fan operation.
Check motor power against unit
power.
2010 MOTOR TEMP
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 ( 2501 SENSOR TYPE ).
Let motor cool down. Ensure proper
motor cooling: Check cooling fan,
clean cooling surfaces, etc.
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.
