Figure 7.8 Output-Side Noise Filter
• Radiated Noise: Electromagnetic waves radiated from the drive and cables create noise
throughout the radio bandwidth that can affect devices.
• Induced Noise: Noise generated by electromagnetic induction can affect the signal line
and may cause the controller to malfunction.
Preventing Induced Noise
Use a noise filter on the output side or use shielded cables. Lay the cables at least 30 cm away
from the signal line to prevent induced noise.
