(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, and GRFC-13 by Kitagawa
Industries are available as data line filters.
As a reference example, the impedance specifications of the ZCAT3035-1330 (TDK) are indicated
below. This impedances are reference values and not guaranteed values.
