(2) Noise 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 NEC TOKIN, GRFC-13 by Kitagawa
Industries, and E04SRM563218 by SEIWA ELECTRIC are available as data line filters.
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.

Between terminals:
625 V AC, 50 Hz/60 Hz 60 s
Between terminal and case:
2000 V AC, 50 Hz/60 Hz 60 s
Note that a diode should be installed to a DC relay or the like.
Maximum voltage: Not less than four times the drive voltage of the relay or
the like.
Maximum current: Not less than twice the drive current of the relay or the
like.
