Description
The temperature of the control board is be-
low the normal temperature range. The drive
is operated at a too low ambient temper-
ature. Check the ambient temperature. In-
crease the ambient temperature or consider
an external heater to increase the tempera-
ture at the drive.
The temperature of the control board is at
the upper limit of the normal temperature
range. Check cooling conditions and load of
the control board. Reduce the load on the
control board or the ambient temperature.
The temperature of the control board has ex-
ceeded its normal temperature range. Check
cooling conditions and load of the control
board. Reduce the load on the control board
or the ambient temperature.
The temperature of the control board has
reached a critical level. Check cooling condi-
tions and load of the control board. Reduce
the load on the control board or the ambient
temperature.
There is a temperature imbalance between 1
or more brake chopper IGBT's.
There is a temperature imbalance between 1
or more IGBT's.
An excessive thermal imbalance between the
IGBT modules has been detected. Check the
condition of IGBT modules their connections
the cooling and the driver boards.
There is a temperature imbalance between 1
or more brake chopper IGBT's.
There is a temperature imbalance between 1
or more IGBT's.
A too high temperature is detected in the
connected AHF (Advanced Harmonic Filter).
Output has been derated to 50%.
