2 CABLE CONNECTION
This section describes information relating to the physical Ethernet
connection.
CAUTION
1 Before connecting or disconnecting the cable to or
from the FAST Ethernet/FAST Data Server, make
sure that the power to the CNC is turned off.
2 Please inquire of each manufacturer about the
construction of network or the condition of using
the equipment except the FAST Ethernet/FAST
Data Server (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
FAST Ethernet or FAST Data Server.
