[Wiring examples using duct (incorrect example and corrected example)]
(11)The influence of noise may be reduced by installing ferrite cores to the cable
connected to the LD75 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.

The drive units are placed
near the noise source.
The connection cable
between the LD75 and
drive units is too long.
The LD75 and drive units
are placed closely.
The connection cable
between the LD75 and
drive units is separately
laid from the power line
(in this example, the cable
is outside of the duct) and
is as short as possible.
