(d) Li
ne noise filter (FR-BSF01/FR-BLF)
This filter is effective in suppressing noises radiated from the power supply side and output sid
e of
the servo amplifier and also in suppressing high-frequency leakage current (0-phase current). It
especially affects the noises between 0.5 MHz and 5 MHz band.
Connection diagram Dimensions [Unit: mm]
The line noise filters can be mounted on lines of the main power
supply (L1/L2/L3) and of the servo motor power (U/V/W). Pass
each of the wires through the line noise filter an equal number of
times in the same direction. For wires of 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. Otherwise, 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.

(e) Rad
io noise filter (FR-BIF(-H))
This filter is effective in suppressing noises radiated from the power supply side of the servo amplifier
especially in 10 MHz and lower radio frequency bands. The FR-BIF is designed for the input only.
200 V class/100 V class: FR-BIF
400 V class: FR-BIF-H
Connection diagram Dimensions [Unit: mm]
Make the connection cables as short as possible. Grounding is
always required.
When using the FR-BIF with a single-phase power supply, always
insulate the lead wires that are not used for wiring.

Varistor for input power supply (recommended)
Varistors are effective to prevent exogenous noise and lightning surge from entering the serv
o
amplifier. When using a varistor, connect it between each phase of the input power supply of the
equipment. For varistors, the TND20V-431K, TND20V-471K and TND20V-102K, manufactured by
NIPPON CHEMI-CON, are recommended. For detailed specification and usage of the varistors, refer
to the manufacturer catalog.
