(d) Line noise filter (FR-BSF01, FR-BLF)
This filter is effective in suppressing noises radiated from the power supply side and output side of the
servo amplifier and also in suppressing high-frequency leakage current (zero-phase current) especially
within 0.5MHz to 5MHz band.

The line noise filters can be installed on lines of the main power
supply (L1, L2, and L3) and of the servo motor power (U, V, and
W). Pass each of the wires through the line noise filter an equal
number of times in the same direction. For the main power supply,
the effect of the filter rises as the number of passes increases, but
generally four passes would be appropriate. For the servo motor
power lines, passes must be four times or less. Do not pass the
grounding wire through the filter, or the effect of the filter will drop.
Wind the wires by passing through the filter to satisfy the required
number of passes as shown in Example 1. If the wires are too
thick to wind, use two or more filters to have the required number
of passes as shown in Example 2. Place the line noise filters as
close to the servo amplifier as possible for their best performance.
