Notice
When using filters which SIEMENS have not released for SIMODRIVE 6SN11,
harmonics can be fed back into the line supply which can damage/disturb
devices connected to that line supply.
It is not permissible to connect other loads to the line filter output.
The HF commutating reactors have the task of limiting harmonics fed back into
the line supply and saving the energy for step–up control operation in conjunc-
tion with infeed and regenerative feedback modules. The matching HF commu-
tating reactor, according to the selection table is required when connecting the
uncontrolled 28 kW infeed and the controlled infeed/regenerative feedback mo-
dules to the line supply.
The line filters limit the cable–borne faults emitted from the drive converter units
to permissible EMC values for industry. In conjunction with consequentially im-
plementing the plant/system in accordance with the Planning Guide and the
EMC Guidelines for SIMODRIVE, SINUMERIK, SIROTEC, the limit values at
the installation location are maintained in accordance with EC Guidelines EMC.
The line filter and line filter packages can be used both in sinusoidal as well as
squarewave current operation.
