(c) Cable clamp fitting AERSBAN -
SET
Generally, the earth of the shielded cable may only be connected to the connector's SD terminal.
However, the effect can be increased by directly connecting the cable to an earth plate as shown below.
Install the earth plate near the servo amplifier for the encoder cable. Peel part of the cable sheath to
expose the external conductor, and press that part against the earth plate with the cable clamp. If the
cable is thin, clamp several cables in a bunch.
The clamp comes as a set with the earth plate.

(d) Line noise filter (FR-BSF01, FR-BLF)
This filter is effective in suppressing noises radiated from the power supply side and output side of the
servo amplifier and also in suppressing high-frequency leakage current (zero-phase current) especially
within 0.5MHz to 5MHz band.
Connection diagram Outline drawing [Unit: mm]
Use the line noise filters for wires of the main power supply (L1 L2
L3) and of the motor power supply (U V W). 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 noises 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.
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.
