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:
Table 6- 11
dv/dt filter plus Voltage Peak Limiter
When a dv/dt filter plus Voltage Peak Limiter is used, the pulse frequency of the Power
Module or Motor Module must not exceed 2.5 kHz or 4 kHz respectively. If a higher pulse
frequency is set, then this could destroy the dv/dt filter.
