Noise Filter for Power Supply Input
We recommend using a noise filter for the Servo Drive.
 If no-fuse breakers are installed at the top and the power supply line is wired from the lower duct,
use metal tubes for wiring or make sure that there is adequate distance between the input lines
and the internal wiring. If input and output lines are wired together, noise resistance will decrease.
 The noise filter must be installed as close as possible to the entrance of the control panel. Wire
as shown at the left in the following illustration.
