Possible cause
Too high a temperature in the
heatsink of the power unit or in
the power board.
The heatsink temperature is over
100 °C.
The motor stalled.
There is too heavy a load on the
motor.
There is not a sufficient load on
the motor.
The power of the drive is too
high.
A malfunction in the start angle
identification.
A generic motor control fault
The fan life time is complete.
The Fire mode of the drive is
enabled. The protections of the
drive are not used.
The option board was replaced
by a new one that you have used
before in the same slot. The
parameters are available in the
drive.
The option board was added.
You have used the same option
board before in the same slot.
The parameters are available in
the drive.

Remedy
Check the actual quantity and flow of
cooling air.
Examine the heatsink for dust.
Check the ambient temperature.
Make sure that the switching frequency
is not too high in relation to the ambient
temperature and the motor load.
Check the motor and the load.
Decrease the motor load. If there is no
motor overload, check the temperature
model parameters.
Check the load.
Decrease the load.
Replace the fan and reset the life time
counter of the fan.
The device is ready for use. The drive
starts to use the old parameter settings.
