● Radio noise filter (FR-BIF, FR-BIF-H)
Effectively controls noise transmitted from the power-supply side of the servo amplifier or converter unit, and is especially effective
for radio frequency bands under 10MHz. 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 please connect to the terminal
block of the unit.

● 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 0.5MHz to 5MHz band.

Wind the 3-phase wires in the same direction the same number of winds, and then
connect to the power-supply side and output side of the servo amplifier or converter unit.
Increasing the number of winds on the power-supply side is effective, but normally, the
wire is wound approx. four times. If the wire is thick and hard to wind, use two or more
filters, and make sure that the total of penetrations exceeds the above number. Make sure
that the number of penetrations 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.
