Cause and Assumed cause
correction
An error occurred in EtherCAT master
processing.
An initialization error occurred in the
EtherCAT slave.
An initialization error occurred in the
EtherCAT Coupler Unit.
A major fault level Controller error
occurred.
The Ethernet cable is broken or the
specified cable is not being used.
A connector on the Ethernet cable is
disconnected, the contact is faulty, or
parts are faulty.
A general-purpose Ethernet hub is
connected.
The master failed.
The slave failed.

Correction
Connect the Sysmac Studio and
reconfigure and save the network
configuration information in the mas-
ter again. If this error occurs again,
check that there are no errors in the
slave synchronization settings and
the PDO mapping information, and
correct any errors that are found.
The Module config send method
parameter is sometimes displayed for
a slave in the EtherCAT network con-
figuration on the Sysmac Studio even
if a send method cannot be set. If that
occurs, set the Module config send
method parameter to Do not send and
perform synchronization again. Or,
cycle the power supply to the Ether-
CAT slave. If this error persists,
replace the EtherCAT slave.
Connect the Sysmac Studio to the
USB port on the EtherCAT Coupler
Unit, check the error details, and take
suitable measures for the error.
If a major fault level Controller error
occurs, process data communications
stop. If a Slave Application Error
(84280000 hex) occurs at this time,
this event also occurs. Perform cor-
rections for the major fault level Con-
troller error.
The causes given on the left are pos-
sible if the error occurs from when the
system starts operation or if it always
occurs after a specific time after the
system starts operation.
Use the diagnostic and statistical
information from the Sysmac Studio
and check the EtherCAT communica-
tions status.
If the Ethernet cable between the
master and slave is broken or if the
specified cable was not used, replace
the cable. Or, reconnect the connec-
tor and make sure it is mated cor-
rectly. If a general-purpose Ethernet
hub is connected, replace it with an
EtherCAT Junction Slave.
If the CPU Unit or an EtherCAT slave
fails, replace it.
If this error occurs irregularly, imple-
ment noise countermeasures.

Prevention
Correctly set the slave synchroniza-
tion settings, PDO mapping informa-
tion, and configure and save network
configuration information in the mas-
ter.
None
None
Perform preventive measures for
major fault level Controller errors.
Make sure that the cable is not bro-
ken and use the specified cable.
Confirm that the Ethernet cable con-
nector is mated securely.
When branching an EtherCAT net-
work, use an EtherCAT Junction
Slave.
