This section describes information relating to the physical Ethernet
connection.
CAUTION
1 Before connecting or disconnecting cables to and
from the Ethernet board, cut the power supply of
CNC, and make sure that the power is off.
2 Please inqure of each manufacturer about the
construction of network or the condition of using the
equipment except the Ethernet board (hub,
transceiver, cable etc.). When configuring your
network, you must take other sources of electrical
noise into consideration to prevent your network from
being influenced by electrical noise. Make sure that
network wiring is sufficiently separated from power
lines and other sources of electrical noise such as
motors, and ground each of the devices as
necessary. Also, a high and insufficient ground
impedance may cause interference during
communications. After installing the machine,
conduct a communications test before you actually
start operating the machine.
We cannot ensure operation that is influenced by
network trouble caused by a device other than the
Ethernet board.
