(e) Radio noise filter (FR-BIF)
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.
Connection diagram
Outline drawing (Unit: mm)
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.

(f) Varistors for input power supply (Recommended)
Varistors are effective to prevent exogenous noise and lightning surge from entering the servo amplifier.
When using a varistor, connect it between each phase of the input power supply of the equipment. For
varistors, the TND20V-431K and TND20V-471K manufactured by NIPPON CHEMI-CON, are
recommended. For detailed specification and usage of the varistors, refer to the manufacturer catalog.
