DC Bot over voltage The DC over voltage protection of the capacitors in the negative
stack has been triggered.
DC under voltage (SW) The DC software under voltage protection has been triggered.
IGBT check cooling The software IGBT temperature protection has been triggered.
IGBT permanent
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.
IGBT temporary 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.
Loss of phase
The system has detected a loss of supply on at least one phase.
No synchronization The system cannot synchronize on to the network.
SPI Error The DSP has received no response after its request on the SPI port.
Bad Sequence The DSP has detected an inadequate behavior in the sequence.
Out of mains freq.
Limit
The system has detected that the network frequency is out of
range.
Over voltage RMS
The RMS value of the supply voltage is higher than the acceptable
maximum value.
Over volt. Transient
(SW)
The software transient over voltage protection has been triggered.
Over current RMS The system has detected RMS over current.
Over current peak
(SW)
The software peak current protection has been triggered.
Preload problem
The DC capacitors could not be preloaded. The voltage increase on
the DC capacitors during the preload phase is not high enough.
Unbalanced supply The supply imbalance is out of range.
Under voltage RMS
The RMS value of the supply voltage is lower than the acceptable
minimum value.
Unstable mains frequ. The network frequency is varying too fast.
Wrong phase rotation
The filter is fed by a supply system, which has the wrong phase
rotation.
SPI Timeout
Internal system error
Mismatch between
units
Different units in a filter system have different settings (e.g. 3-wire
and 4-wire setting) or are connected in a different way.
Remark: Maximum limits for certain parameters are given in the detailed manuals
