● Radio noise filter (FR-BIF)
This filter effectively controls noise emitted from the power supply side of the servo amplifier and is especially effective for radio frequency
bands 10MHz or lower. The FR-BIF is designed for the input only.

● Line noise filter (FR-BSF01, FR-BLF)
This filter is effective in suppressing radio noise emitted from the power supply side or output side of the servo amplifier, and also in
suppressing high-frequency leakage current (zero-phase current), especially within 0.5 to 5MHz band.

Connections
Use the line noise filter for wires of the main power supply (L1, L2, L3) of the servo
amplifier, and of the motor power supply (U, V, W). Pass each of the 3-phase wires
through the line noise filter equal times in a 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 to pass through the filter as the required number of passes as shown in the
diagram below. If the wires are too thick to wind, use two or more filters to have the
required number of passes. Place the line noise filters as close to the servo amplifier as
possible for their best performance.

Servo amplifier
This filter is not connectable to output side of the servo amplifier.
Wiring should be as short as possible. Grounding is always required.
Be sure to insulate the unused wire when using FR-BIF with 1-phase power.
● Surge suppressor
Attach surge suppressors to AC relays and AC valves around the servo amplifier. Attach diodes to DC relays and DC valves.
Sample configuration
Surge suppressor :
972A-2003 504 11 (rated 200VAC, manufactured by Matsuo Electric Co., Ltd.)
A diode with breakdown voltage 4 or more times greater than the relay’s drive voltage, and with current capacity 2 or more
times greater than the relay’s drive current.
● Data line filter
Noise can be prevented by attaching a data line filter to the pulse output cable of the pulse train output controller (QD75D, etc.) or motor
encoder cable.
Sample configuration
Data line filter examples: ESD-SR-25 (manufactured by NEC TOKIN Corporation) or ZCAT3035-1330 (manufactured by TDK Corporation)
