■Techniques for noises radiated by the servo amplifier that cause peripheral equipment to

Noises produced by the servo amplifier are classified into those radiated from the cables connected to the servo amplifier and

its main circuits (input/output), those induced electromagnetically or statically by the signal cables of the peripheral equipment

located near the main circuit cables, and those transmitted through the power supply cables.
