To properly mount the filters, the enclosure should have an
unpainted metallic surface. This allows for more surface area to be
in contact with the filter housing and provides a lower impedance
path between this housing and the back plane. The back panel, in
turn, has a high frequency ground strap connection to the enclosure
frame or earth ground.
4.4.1 INPUT POWER FILTERING
The Danaher Motion SERVOSTAR S electronic system
components require EMI filtering in the input power leads to meet
the conducted emission requirements for the industrial
environment. This filtering blocks conducted-type emissions from
exiting onto the power lines and provides a barrier for EMI on the
power lines.
Care must be taken to adequately size the system. The type of filter
is based on the voltage and current rating of the system and
whether the incoming line is single or three-phase. One input line
filter is used for multi-axis control applications. These filters are
mounted as close to the incoming power as possible so noise is not
capacitively coupled into other signal leads and cables. Several
manufacturers of these filters are listed below. They should be able
to recommend the best filter design for most typical motor control
applications. Danaher Motion has also provided specific filter
recommendations that adequately attenuate the conducted noise to
levels well below the CE limits. The recommendations are:
− Filter should be mounted on the same panel as the drive.
− Filter should be mounted as close as possible to incoming
cabinet power.
− When mounting the filter to the panel, remove any paint or
material covering. Use an unpainted metallic back panel if
possible.
− Filters are provided with an earth connection. All ground
connections are tied to ground.
− Filters can produce high leakage currents. Filters must be
earthed before connecting the supply!
− Filters should not be touched for a period of 10 seconds after
removing the supply.
