(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 10 MHz and lower radio frequency bands. The FR-BIF is designed for the
input only.
Connection diagram
Dimensions [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 lead wires that are not used for wiring.

(f) Varistor 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.
