(d) Line noise filter (FR-BSF01)
This filter is effective in suppressing noises radiated from the power supply side and output side of
MELSERVO-J2M and also in suppressing high-frequency leakage current side (zero-phase
current) especially within 0.5MHz to 5MHz band.
Connection diagram Outline drawing [Unit: mm] ([Unit: in.])
Wind the 3-phase wires by the equal number of times in the
same direction, and connect the filter to the power supply side
and output side of MELSERVO-J2M
The effect of the filter on the power supply side is higher as the
number of winds is larger. The number of turns is generally four.
If the wires are too thick to be wound, use two or more filters
and make the total number of turns as mentioned above.
On the output side, the number of turns must be four or less.
Do not wind the grounding wire together with the 3-phase wires.
The filter effect will decrease. Use a separate wire for grounding.

(e) Radio noise filter (FR-BIF)...for the input side only
This filter is effective in suppressing noises radiated from the power supply side of MELSERVO-
J2M especially in 10MHz and lower radio frequency bands. The FR-BIF is designed for the input
only.
Connection diagram Outline drawing (Unit: mm) ([Unit: in.])
Make the connection cables as short as possible.
Grounding is always required.
When using the FR-BIF with a single-phase wire, always
insulate the wires that are not used for wiring.
