Siemens SIROTEC Operating Instructions

2.6.7 dv/dt filter compact plus Voltage Peak Limiter
The du/dt filter compact plus Voltage Peak Limiter consists of two components:
●
The du/dt reactor
● The voltage limiting network (Voltage Peak Limiter).
The voltage limiting network cuts-off the voltage peaks and feeds the energy back into the
DC link.
The "du/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.
Note
You
can find a description of the du/dt filter in the "SINAMICS S120 Cabinet Modules" Manual,
Chapter, "Options / L07, du/dt filter compact plus Voltage Peak Limiter".
2.6.8 du/dt filter plus Voltage Peak Limiter
The "du/dt filter plus Voltage Peak Limiter" consists of two components:
●
The du/dt reactor
● The voltage limiting network (Voltage Peak Limiter).
The voltage limiting network cuts-off the voltage peaks to the level of the DC link voltage –
and feeds the energy back into the DC link.
The "du/dt filter plus Voltage Peak Limiter" limits the voltage rate of rise.
Note
You
can find a description of the du/dt filter in the "SINAMICS S120 Cabinet Modules" Manual,
Chapter, "Options / L10, du/dt filter compact plus Voltage Peak Limiter".
2.6.9 EMC shield bus
An
EMC shield bus is incorporated for the use of shielded power cables for the line feeder and
motor feeder cables.
The cable shields for the cables routed to the cabinet must be connected to the EMC shield
bus in accordance with EMC guidelines.
Note
You can find a description in the "SINAMICS S120 Cabinet Modules" Manual, Chapter,
"Options / M70, EMC shield bus.
