CAUSE
Drive IGBT temperature is
excessive. Alarm limit is
120°C.
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.
Measured motor
temperature has exceeded
alarm limit set by
parameter 3503 ALARM
LIMIT.
Motor load is too low due to
e.g. release mechanism in
driven equipment.
Motor is operating in stall
region due to e.g.
excessive load or
insufficient motor power.
Automatic reset alarm
Sleep function has entered
sleeping mode.
Motor Identification Run is
on.
No Start Enable 1 signal
received
No Start Enable 2 signal
received
Drive has received
emergency stop command
and ramps to stop
according to ramp time
defined by parameter 2208
EMER DEC TIME.
WHAT TO DO
Check ambient conditions. See also section
page 291.
Check air flow and fan operation.
Check motor power against unit power.
Check motor ratings, load and cooling.
Check start-up data.
Check fault function parameters.
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.
Check for problem in driven equipment.
Check fault function parameters.
Check motor power against unit power.
Check motor load and drive ratings.
Check fault function parameters.
Check parameter group 31 AUTOMATIC RESET
See parameter groups 40 PROCESS PID SET
1...41 PROCESS PID SET
This alarm belongs to normal start-up procedure. Wait until
drive indicates that motor identification is completed.
Check parameter 1608 START ENABLE 1settings.
Check digital input connections.
Check fieldbus communication settings.
Check parameter 1609 START ENABLE 2 settings.
Check digital input connections.
Check fieldbus communication settings.
Check that it is safe to continue operation.
Return emergency stop push button to normal position.
