Output-Side Noise Filter

■
A noise filter on the output side of the drive reduces inductive noise and radiated noise.
Figure 7.8 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.
