CAUTION
Before attaching or detaching cables, turn off the power
to the PANEL i, and ensure that the power is off.
Please inquire of each manufacturer about the
construction of network or the condition of using the
equipment except the CNC unit (media converter, 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 CNC
unit.
4.11.1 Connecting to Ethernet
Connection to the Ethernet Interface
The 10BASE-T and 100BASE-TX interfaces are available. A hub
(line concentrator) is used to connect the CNC unit to a system. A
typical connection example is shown below.
PANEL i
Twisted pair cable
HUB
Max. 100m
Shield
Some devices (hub, transceiver, etc.) that are needed for building a
network do not come in a dust-proof construction. Using such devices
in an atmosphere where they are subjected to dust or oil mist will
interfere with communications or damage these devices. Be sure to
install such devices in a dust-proof cabinet.
