Refer to EMC Filter Installation
on page 213 for details about EMC filter selection and installation in order to make the
drive compliant with European standards EN61800-3 and the EMC guidelines.

Output-Side Noise Filter
A noise filter on the output side of the drive reduces inductive noise and radiated noise. Figure 8.7 illustrates an example
of 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 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.
