General - Siemens SINAMICS G130 Operating Instructions Manual

General

Description
The dV/dt filter plus voltage peak limiter comprises two components: the dV/dt reactor and
the Voltage Peak Limiter, which cuts off the voltage peaks and returns the 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
