dv/dt filter plus Voltage Peak Limiter

6.3.1

Description

The dV/dt filter plus voltage peak limiter comprises two components: The dV/dt reactor and
the voltage-limiting network (voltage peak limiter) which cuts of the voltage peaks and
returns energy to the DC link. The dV/dt filters plus voltage peak limiter must be used for
motors for which the proof voltage of the insulation system is unknown or insufficient.
dV/dt filters plus voltage peak limiters limit the rate of voltage rise to values < 500 V/µs and
the typical voltage peaks with rated line voltages to the values below:
< 1000 V at U
< 1250 V at 660 V < U
Components
The order numbers of the individual components (dV/dt reactor and voltage peak limiter) are
listed in the following table:

Risk of destruction during operation with increased pulse frequency
When a dV/dt filter is used, the pulse frequency of the Motor Module must not exceed 2.5
kHz or 4 kHz. If a higher pulse frequency is set, then this could destroy the dV/dt filter.
