The DC over voltage protection of the capacitors in the negative
stack has been triggered.
The DC software under voltage protection has been triggered.
The software IGBT temperature protection has been triggered.
The IGBT modules report an error that cannot be cleared by the
system. This error can be due to peak over current or too low
control voltage for the IGBT drivers.
The IGBT modules report a transient error that could be cleared by
the system. This error can be due to peak over current or too low
control voltage for the IGBT drivers.
The system has detected a loss of supply on at least one phase.
The system cannot synchronize on to the network.
The DSP has received no response after its request on the SPI port.
The DSP has detected an inadequate behavior in the sequence.
The system has detected that the network frequency is out of
range.
The RMS value of the supply voltage is higher than the acceptable
maximum value.
The software transient over voltage protection has been triggered.
The system has detected RMS over current.
The software peak current protection has been triggered.
The DC capacitors could not be preloaded. The voltage increase on
the DC capacitors during the preload phase is not high enough.
The supply imbalance is out of range.
The RMS value of the supply voltage is lower than the acceptable
minimum value.
The network frequency is varying too fast.
The filter is fed by a supply system, which has the wrong phase
rotation.
Internal system error
Different units in a filter system have different settings (e.g. 3-wire
and 4-wire setting) or are connected in a different way.
