(12) The influence of noise may be reduced by installing ferrite cores to the cable
connected to the AD75 as a noise reduction technique.
For the noise reduction techniques related to connection with the servo amplifier,
also refer to the instruction manual of the servo amplifier.
(13) If compliance with the EMC directive is not required, the influence of external
noise may be reduced by making the configuration compliant with the EMC
directive.
For the configuration compliant with the EMC directive, refer to Chapter 3 "EMC
directive and low voltage directive" in the User's Manual (Hardware) of the used
CPU module.
(14) Installing ferrite cores and noise filter to the power supply line of the PLC as
noise reduction techniques may have effects on external noise.
(Example) • Ferrite cores
Type: ZCAT3035-1330 (TDK ferrite core)
• Noise filter
Type: MXB-1210-33 (DENSEI-LAMBDA noise filter)
