4. EMC COUNTERMEASURE PARTS
4.5.2 Precautions
(1) When the line noise filter is used for the main circuit power side in the servo amplifier (converter unit), the
effect of the filters is produced as the number of passes increases. The appropriate number of passage is
four times.
(2) When using the line noise filter for the cable connected to the servo amplifier power output, pass through
four times or less.
(3) Do not pass the earth wire through the line noise filter. Doing so may result in reducing the effect.
(4) Place the line noise filter as close to the servo amplifier as possible so that the effect of suppressing noises
can increase.
(5) The line noise filter can be also used not only for the cables connected to the main circuit power supply in
the servo amplifier (converter unit) or the cables connected to the servo amplifier power output but also the
servo motor brake cable, encoder cable, and control signal cable. Pass through four times or less in this
case. However, prevent the line noise filter from damaging the servo amplifier, converter unit, drive unit,
and/or servo motor in considering the flexing life of the encoder cable.
