-1 Error List
84B70000
SII Verification Error
An error occurred in SII data
of the EtherCAT slave com-
munications controller.
• 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
√
84B90000
Synchronization
Interruption Error
Synchronization interrup-
tion did not occur within the
specified period.
• Incorrect EtherCAT syn-
chronization setting of the
host controller
• Failure of the EtherCAT
slave communications con-
troller or false detection
√
84BA0000
Bootstrap State
Transition Request
Error
The state transition to
unsupported Bootstrap was
requested.
• The EtherCAT master
requested the transition of
unsupported Bootstrap
√
88100000
Communications
Synchronization
Error
Communications were not
established consecutively
because the synchroniza-
tion with the EtherCAT Mas-
ter could not be achieved.
• The power supply to the
host controller was inter-
rupted during PDO commu-
nications.
• An EtherCAT communica-
tions cable is disconnected,
broken, short-circuited, or
has a contact failure in a
daisy chain configuration.
• An EtherCAT communica-
tions cable is broken,
short-circuited, or has a
contact failure in a ring
topology configuration.
• Noise
• Failure of the EtherCAT
physical layer of a Servo
Drive
√
88120000
Safety Communica-
tions Timeout
A communications timeout
occurred in safety process
data communications with
the Safety CPU Unit.
• 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
√
