Filter modules and line filter
1)
In order to maintain the EMC Law, the SIMODRIVE 611 system has filter modu-
les and line filters. An essential prerequisite in maintaining the limit values is
that, in addition to the use of filter modules/line filters, the cabinet has been de-
signed and constructed in line with an EMC–correct design. The installation and
connection specifications according to pp.1-54~1-56 must be observed.
These EMC limit values can also be fulfilled using other suitable measures; an
EMC investigation should be made on a case–for–case basis.
Note
When using filter modules (for I/R modules for square–wave current operation),
a separate commutating reactor is not required.
When using an adaptation transformer, this does not mean that the filter mo-
dule or line filter are not required, i.e. the transformer does not replace a filter
module or line filter.
When using filters, which SIEMENS have not released for SIMODRIVE
6SN611, line harmonics and disturbances can occur, which could damage/in-
terfere with other equipment connected to that line supply.
When using line filters (for I/R modules for sinusoidal current operation), the
appropriate HF commutating reactor must be connected in series, refer to
p. 1-46, Connection diagram Fig. 3-13.
Information regarding machines which are located close to one another at diffe-
rent potentials:
Two machines are located close to one another and are connected to the same
distribution through separate cables.
If a SIMODRIVE drive with controlled DC link (I/R module) without filter module
or line filter, is used in one of the two machines, then potential equalization cur-
rents can flow when both machines are connected.
Counter–measure: Directly connect the machines through a short PE cable or
use a filter module/line filter in front of the SIMODRIVE drive.

may only be used with supplies with grounded neutral point (TN supply net-
works).
When connected to other line supplies, an isolating transformer must be
used.
