Description or possible cause
The room temperature is over the
allowed range.
Keep the installation location at room
temperature within the specified
limits.
Problem present in the drive internal
temperature sensor.
Contact the Technical Service.
Acceleration / deceleration time too
short compared to the load inertia.
Increase the acceleration
/deceleration time.
The load exceeds the drive rated
power.
Increase the drive rated power.
The drive attempts to start the motor
while spinning.
Ensure the correct programming
spin start conditions. Set the load
inertia and the parameters which
enable the speed search properly.
Note: Adequate spin start conditions
fulfilment depends on each
installation.
Ground fault or short circuit
produced.
The mechanic brake enters too
quickly.
Check the mechanic brake.
The power circuit components
overheated due to a cooling fan
malfunction.
Check the cooling fan. Verify it is
correctly powered and not blocked by
dirt.
Caution: Starting the drive without correcting anomalies may
damage the IGBTs.
The deceleration time is too short
compared to the load inertia.
Increase the deceleration time.
Excessive energy regeneration in
the drive.
Use an optional brake resistor
(dynamic brake units).
Check the supply line voltage.
Delete the circuit fault connected by
the input fault terminal configured.
