4. EMC COUNTERMEASURE PARTS
[SF1252, SF1253 wire connection method]
1) Peel the wire insulator.
2) Insert the core of the cable into the opening, and tighten with the slotted screwdriver. In addition,
connect the cables to the terminals of SF1252 or SF1253 in a one-to-one connection.

4.3 Ferrite core (Data line filter)
Noise can be prevented by installing a data line filter onto the cables connected to the servo amplifier. The data
line filter in the following is one such example.
Model
ZCAT3035-1330
(Manufactured by TDK)
Note. The above values of impedance do not refer to the guaranteed values but the impedance values of the data line filter
including those of the cable (measured reference values).
ESD-SR-250 by NEC TOKIN, E04SRM563218 by SEIWA ELECTRIC, etc. are also available.
