Description
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 is derated to 50%.
A too high temperature has been detected in
the connected AHF (Advanced Harmonic Fil-
ter). Operation of the drive is stopped.
Drive has left service mode. Power cycle is re-
quired to reset the drive.
The drive is in 24V backup mode. The control
section (including parameter configurations)
and installed options are kept operational.
Drive is in service mode.
The 24V supply is outside its normal operat-
ing range.
The voltage of the internal 3.3V supply is be-
low its normal operating range.
The voltage of the internal 28V supply is be-
low its normal operating range.
The gate driver supply voltage is outside its
normal operating range.
A gate driver fault is detected or a link to the
gate driver is broken.
A power supply fault on the power board has
been detected.
