● Radio noise filter (FR-BIF, FR-BIF-H)
This filter effectively controls noise emitted from the power supply side of the servo amplifier or converter unit, and is especially
effective for radio frequency bands 10MHz or lower. Available only for input.

1. Cannot be connected to output side of the servo amplifier or converter unit.
2. Wiring should be as short as possible, and connect the wires to the terminal block of the unit.
3. Be sure to insulate the unused wire when using FR-BIF with the 1-phase wire.

● Heat sink outside attachment (MR-(J)ACN)
By mounting the heat sink outside attachment on the converter unit or servo amplifier, the heat generating section can be mounted
outside the control box. This makes it possible to dissipate the unit’s heat to outside the box. Approx. 50% of the heating value can
be dissipated with this method, and the control box dimensions can be downsized.
● Line noise filter (FR-BSF01, FR-BLF)
This filter is effective in suppressing radio noise emitted from the servo amplifier’s or converter unit’s power supply side or output
side, and high-frequency leakage current (zero-phase current). Especially effective in the 0.5 to 5MHz band.

Wind 3-phase wires an equal number of times in the same direction, and connect them to
the power supply side and output side of the servo amplifier or converter unit. The effect
of the filter on the power supply side rises as the number of winds increases, but generally
wind the wires four times each. If the wire is thick and hard to wind, use two or more filters,
and make sure that the total number of turns exceeds the above number. Make sure that
the number of turns on the output side is four times or less. Do not wind the grounding
(earth) wire together with the 3-phase wires. The effect of the filter will drop. Use a
separate wire for grounding.
