Description
An undefined communica-
tions state change com-
mand was received.
A signal for synchronous
communications could not
be detected.
PDO communications were
interrupted for the allow-
able period or longer.
The initialization of Ether-
CAT slave communications
controller failed.
An error occurred in SII data
of the EtherCAT slave com-
munications controller.
Synchronization interrup-
tion did not occur within the
specified period.
The state transition to
unsupported Bootstrap was
requested.
Communications were not
established consecutively
because the synchroniza-
tion with the EtherCAT Mas-
ter could not be achieved.
A communications timeout
occurred in safety process
data communications with
the Safety CPU Unit.
Assumed cause
• An undefined communica-
tions state change com-
mand was received
• Noise
• Error of the EtherCAT slave
communications controller
• An EtherCAT communica-
tions cable is disconnected,
loose, or broken
• Host controller error
• Data was incorrectly over-
written in the non-volatile
memory of the EtherCAT
slave communications con-
troller
• Failure of the EtherCAT
slave communications con-
troller
• Data was incorrectly over-
written in the non-volatile
memory of the EtherCAT
slave communications con-
troller
• Failure of the EtherCAT
slave communications con-
troller or false detection
• Incorrect EtherCAT syn-
chronization setting of the
host controller
• Failure of the EtherCAT
slave communications con-
troller or false detection
• The EtherCAT master
requested the transition of
unsupported Bootstrap
• The power supply to the
host controller was inter-
rupted during PDO commu-
nications
• An EtherCAT communica-
tions cable is disconnected,
loose, broken, or has a con-
tact failure
• Noise
• A setting is not correct. The
setting of the safety task
period of the Safety CPU
Unit is too short
• There is excessive noise
• The Safety CPU Unit or
safety slave entered a sta-
tus where it could not con-
tinue safety process data
communications
