(d)Line noise filter (FR-BLF, FR-BSF01)

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.

Connection diagram

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 the servo amplifier.

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 the servo amplifier especially in 10MHz and lower radio frequency bands. The FR-BIF is designed for the input only.

Make the connection cables as short as possible. Grounding is always required.
