(2) Nois
e reduction techniques
(a) Data line filter (recommended)
Noise can be prevented by installing a data line filter onto the encoder cable, etc.
For example, ZCAT3035-1330 by TDK, ESD-SR-250 by TOKIN, GRFC-13 by Kitagawa Industries,
and E04SRM563218 by SEIWA ELECTRIC are available as data line filte
rs.
As a reference example, the impedance specifications of the ZCAT3035-1330 (TDK) are indicated
below. These impedances are reference values and not guaranteed values.

(b) Surge killer (recommended)
Use of a surge killer is recommended for AC relay, magnetic contactor or the like near the servo
amplifier. Use the following surge killer or equivalent.

Cable clamp fitting AERSBAN-_SET
Generally, connecting the grounding of the shielded wire to the SD terminal of the connector
provides a sufficient effect. However, the effect can be increased when the shielded wire is
connected directly to the grounding plate as shown below.
Install the grounding plate near the servo amplifier for the encoder cable. Peel part of the cabl
e
sheath to expose the external conductor, and press that part against the grounding plate with the
cable clamp. If the cable is thin, clamp several cables in a bunch.
The cable clamp comes as a set with the grounding plate.

(d) Li
ne noise filter (FR-BSF01/FR-BLF)
This filter is effective in suppressing noises radiated from the power supply side and output sid
e of
the servo amplifier and also in suppressing high-frequency leakage current (0-phase current). It
especially affects the noises between 0.5 MHz and 5 MHz band.
Connection diagram Dimensions [Unit: mm]
The line noise filters can be mounted on lines of the main power
supply (L1/L2/L3) and of the servo motor power (U/V/W). Pass
each of the wires through the line noise filter an equal number of
times in the same direction. For wires of 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 servo motor
power lines, passes must be four times or less. Do not pass the
grounding wire through the filter. Otherwise, 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.
