The line filters limit the cable--borne noise and disturbances, originating from the
converter units, to permissible EMC values for industrial environments. If the
system is consequentially executed in--line with the Configuration Manual and
the EMC Guidelines for SIMODRIVE, SINUMERIK, SIROTEC, then the prereq-
uisites are created so that the limit values at the installation location will be in
compliance with the EU Directives for EMC.
The line filters can be used both for sinusoidal current as well as squarewave
current operation.
The mounting/installation and connection regulations as listed in Chapter 9.1
must be carefully observed.
For more detailed information regarding an EMC--correct design, refer also to
the EMC Guidelines for SINUMERIK (Order No.: 6FC5297--0AD30--0AP1).
Other suitable measures can also be adopted to comply with the EMC limits. An
EMC examination is necessary in particular cases.
Note
The line supply connection conditions as specified in Section 7.1 must always
be observed. If the line supply does not comply with the requirements
according to EN--/IEC 61000--2--4 Class 3, then the filters could be overloaded.
Even if a matching transformer is used this does not mean that the HF/HFD
reactor or line filter can be eliminated.
Optional line filter rows that are coordinated with the power range are also avail-
able with the SIMODRIVE 611 digital converter system. These line filters differ
with regard to the frequency range in which they reduce the conducted emis-
sions.
