L07, Dv/Dt Filter Compact Plus Voltage Peak Limiter - Siemens SINAMICS S120 Manual

Options

9.23 L07, dV/dt filter compact plus Voltage Peak Limiter

Note
EMC shield bus
To allow the power cable shield to be connected in conformance with EMC requirements, an
additional EMC shield bus (M70 option) is factory fitted at the converter input and output.
Note
It is not possible to combine insulation monitoring and line filter
It is not possible to use the insulation monitoring function (option L87) in conjunction with the
optional line filter.
Note
Maximum permissible motor cable length
The maximum permissible total motor cable length when using the line filters in conjunction
with Basic Line Connection Modules is 100 m.
The maximum permissible total motor cable length when using the line filter in conjunction
with an Active Line Module is 300 m.
Shielded motor cables must always be used.

Availability of option
This option is available for the following S120 Cabinet Modules:
● Motor Modules
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.
The rate of voltage rise is limited to < 1600 V/µs, the peak voltages are limited to < 1400 V.
Option L07 is accommodated in a supplementary cabinet with a width of 600 mm, which is
arranged to the right of the Motor Modules.
