14.6 EMC Countermeasure Parts
14.6.1 Shield Clamp Fitting
The effect can be enhanced by connecting the cable directly to the earthing plate. Install an earthing plate near each panel's
outlet (within 10cm), and press the cable against the earthing plate with the clamp fitting. If the cables are thin, several can be
bundled and clamped together. Securely earth the earthing plate with the frame ground. Install directly on the cabinet or
connect with an earthing wire.
14.6.2 Ferrite Core
Noise can be suppressed by installing a ferrite core to the cable if the power cable and encoder cable, which are led from
outside of the control panel, are the noise sources.
Specify the frequency of radiated noise and select the ferrite with high impedance corresponding to the frequency.
By wrapping the cable around the ferrite core according to the cable diameter as shown in the example, the impedance rises,
obtaining a better effect.
