Yaskawa J1000 Compact V/f Control Drive - Manual (Page 190)

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.

u EMC Filter Installation
This drive is tested according to European standards IEC/EN 61800-5-1 and it complies with
the EMC guidelines. Refer to EMC Filter Installation on page 249 for details about EMC
filter selection and installation.
u Zero-Phase Reactor
A zero-phase reactor can be used to reduce the noise on the input and output sides of the drive.
