Item
Check that the MAC ID selected on the node address setup
switch is not a duplicate of the MAC ID selection for any
other connected device.
Check whether the correct number of I/O points is selected
on the slot setup switch. Also, check that the setting agrees
with the master's transmission/reception word count.
Check that the baud rate (transmission rate) selected on the
FUNC1 setup switch agrees with the system's transfer rate.
Check that the data swap, mount base partition, and output
module output status settings selected on the FUNC2 setup
switch are correct.
Check that the overall cable length and drop line lengths of
the network are within the specified ranges which vary with
the communication speed (see Section 6.1, "Cabling").
Check that the network cables are positioned away from
motive power lines and other noise induction sources.
Check that the current flowing in each cable is within the
permissible value range (see Section 6.1, "Cabling").
Check that the employed cables comply with the
specifications (see Section 6.1, "Cabling").
Check that the color-identified cables are connected to the
proper connectors (see Section 6.1, "Cabling").
Check that the shield-type connector is firmly inserted and
tightened with its retaining screws installed.
Check that the open-type connector cable connection is
made by crimping a compression terminal onto the cable and
fastening the cable to the connector with 5±1 kg･cm torque.
You are not allowed to connect two cables to the open-type
connector. Check that two cables are not connected to it.
Check that the ends of the main line are connected to the
CAN-H and CAN-L signals, respectively. Ensure that the
signals are not connected to intermediate points of the main
line.
Check that the resistance value of the terminating resistor is
121 Ω±1% (1/4 W or higher).
Check that the communication cable shield is grounded only
at one place near the center of the network. Also, check
that the V- is grounded from one power supply within the
network.
Check that Class D grounding is provided separately from
motor and drive system grounding.
