■
Data line filter (recommended)
Noise can be prevented by installing a data line filter onto cables such as the encoder cable.
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 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.
[Unit: mm]
■
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.
Ex.
CR-50500 (Okaya Electric Industries)
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 two times the drive current of the relay or the like
