4.11 Other connections
When a dV/dt filter compact plus Voltage Peak Limiter is used, the drive must not be
continuously operated with an output frequency lower than 10 Hz.
A maximum load duration of 5 minutes at an output frequency lower than 10 Hz is
permissible, provided that the drive is operated with an output frequency higher than 10 Hz
for a period of 5 minutes thereafter, or deactivated..
Uninterrupted duty at an output frequency less than 10 Hz can produce thermal overload
and destroy the dV/dt filter.
When a dV/dt filter compact plus Voltage Peak Limiter is used, the pulse frequency of the
Power Module must not exceed 2.5 kHz or 4 kHz. Setting a higher pulse frequency can
lead to destruction of the dV/dt filter.
CAUTION
When a dV/dt filter compact plus Voltage Peak Limiter is used, the drive must not be
operated without a connected motor, otherwise the filter could be destroyed.
Note
It is permissible to set pulse frequencies in the range between the rated pulse frequency and
the relevant maximum pulse frequency when a dV/dt filter compact plus Voltage Peak
Limiter is used. "Current derating as a function of the pulse frequency" of the converter must
be observed here (refer to the Technical data).
