Emc Filter Installation - YASKAWA V1000 Technical Manual

• 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.

Reducing Radiated/Radio Frequency Noise
The drive, input lines, and output lines generate radio frequency noise. Use noise filters on input and output sides and
install the drive in a metal enclosure panel to reduce radio frequency noise.
Note: The cable running between the drive and motor should be as short as possible.
