13.9.7 Line noise filter (FR-BLF)
POINT
This section explains how to use the line noise filter unique to servo amplifiers
with a large capacity. Other noise reduction products are the same as those
for servo amplifiers with 22kW or less. Refer to section 11.17.
This filter is effective in suppressing noises radiated from the power supply side and output side of the
converter unit, drive unit and also in suppressing high-frequency leakage current (zero-phase current)
especially within 0.5MHz to 5MHz band. The filters are used with the converter power supply wires (L
1
L

L

)
and drive unit power wires (U
V W).
(1) Usage
Pass the 3-phase wires through four line noise filters. When using the line noise filters with the power wires,
passing the power wires together with the ground wire will reduce the filter effect. Run the ground wire
separately from the power wires.
Use four FR-BLFs.
