General

Description
The dV/dt filter compact plus Voltage Peak Limiter comprises two components: the dV/dt
reactor and the voltage-limiting network (Voltage Peak Limiter), which cuts off the voltage
peaks and feeds back the energy into the DC link. The dV/dt filter compact plus Voltage
Peak Limiter is designed for use with motors for which the voltage strength of the insulation
system is unknown or insufficient.
The dV/dt filter compact plus Voltage Peak Limiter limits the voltage load on the motor
cables to values in accordance with the limit value curve A in compliance with IEC/TS
60034-25:2007.
The rate of voltage rise is limited to < 1600 V/µs, the peak voltages are limited to < 1400 V.
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.
Uninterrupted duty at an output frequency less than 10 Hz can produce thermal overload
and destroy 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.
CAUTION
Provisions for component cooling must be made at the installation site. Power loss data are
given in the technical specifications.
