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.
