■Techniques for noises radiated by the converter unit/drive unit that cause peripheral
equipment to malfunction
Noises produced by the converter unit/drive unit are classified into those radiated from the cables connected to the converter
unit/drive unit 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.
