Output-Side Noise Filter
■
A noise filter on the output side of the drive reduces inductive noise and radiated
noise. Figure 7.6
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.

Figure 7.6 Output-Side Noise Filter
Electromagnetic waves radiated from the drive and
cables create noise throughout the radio bandwidth that
can affect devices.
Noise generated by electromagnetic induction can affect
the signal line and may cause the controller to
malfunction.
