■Radio noise filter (FR-BIF(-H))
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(-H) is designed for the input only.
100 V class/200 V class: FR-BIF
400 V class: FR-BIF-H
Connection diagram
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.
