n Output-Side Noise Filter
A noise filter on the output side of the drive reduces inductive noise and radiated noise.
output-side noise filter wiring.
NOTICE: Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits. Improper application of noise filters could
result in damage to the drive.

• Radiated Noise: Electromagnetic waves radiated from the drive and cables create noise throughout the radio bandwidth
that can affect surrounding 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.
