■Noise reduction techniques for the network cable
Take measures against noise for both ends of the network cable.
If using the network cable in an environment with excessive noise, directly connect the shield of the cable to the ground plate
with cable clamp fittings at a place 200 mm to 300 mm or less from the servo amplifier.
When connecting the network cable from outside the cabinet, connect it to the ground plate at a place 5 mm to 10 mm away
from the cabinet entrance.
To reinforce noise reduction techniques, installing a data line filter (TDK ZCAT1730-0730) to the network cable is
recommended. Install the data line filter to a place 80 mm or less from the servo amplifier.
