(d) Line noise filter (FR-BSF01, FR-BLF) This filter is effective in suppressing no ises radiated from the power supply side an d output side of the servo amplifier and also in suppressing high- frequency leakage current (zero-phase current) especially within 0.5MHz to 5MHz band.

Use the line noise filters for wires of the main power supply

(L1L2 L3) and of the motor power supply (U VW). Pass

each of the 3-phase wires through the line noise filter an equal

number of times in the same direction. For 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 motor power

supply, passes must be four times or less. Do not pass the

grounding (earth) wire through the filter, or 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) Radio noise filter (FR-BIF-(H)) This filter is effective in suppressing no ises radiated from the power supply side of the servo amplifier especially in 10MHz and lower radio frequency bands. The FR- BIF-(H) is designed for the input only.

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 wires that are not used for wiring.
