(c) Techniques
for
noises radated by the servo amphfier that cause peripheral devices
to
malfunction
Noises produced by the servo amphfier are classfled into those radiated
from
the cables connected
to the servo amphfier and
its
main circuits (input and output circuits), those induced
electromagnetically or statically by the signal cables
of
the peripheral devices located near the main
circuit cables, and those transmitted through the power supply cables.
