A-4-1 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
√ P. A-16 1
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
√ P. A-16 2
84BA0000 Bootstrap State
Transition Request
Error
The state transition to
unsupported Bootstrap was
requested.
• The EtherCAT master
requested the transition of
unsupported Bootstrap
√ P. A-16 2
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
√ P. A-16 3
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
√ P. A-16 4
98200000 Absolute Value
Cleared
The multi-rotation counter of
the absolute encoder was
cleared.
• The multi-rotation counter of
the absolute encoder was
cleared
√ P. A-16 4
081C0000 Capacitor Lifetime
Warning
The capacitor built into the
Servo Drive reached the
service life.
• The operating time of the
capacitor in the Servo Drive
exceeded the service life
