AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
002C Synchroniza-
tion Error
A signal for synchronous
communications could not
be detected.
Noise Take noise countermeasures if
excessive noise affects the Ether-
CAT communications cable.
Error of the EtherCAT
slave communications
controller
If this event occurs again after you
cycled the power supply, replace
the Servo Drive.
002D Synchroniza-
tion Interrup-
tion Error
Synchronization interrup-
tion did not occur within
the specified period.
Incorrect EtherCAT syn-
chronization setting of the
host controller.
Set the synchronization setting of
the host controller according to the
synchronization specifications for
the EtherCAT slave.
Failure of the EtherCAT
slave communications
controller or false detec-
tion
If this event does not occur after
you cycled the power supply, use
the product continuously. It is sup-
posed that a temporary error
occurred due to a read error. If this
event occurs again, the Servo Drive
is faulty. Replace the Servo Drive.
0030 DC Setting
Error
A mistake was made in the DC Mode operation setting. Check the DC Mode setting, and
then download it to the EtherCAT
master again.
0034 Communica-
tions Synchro-
nization Error
Communications were not
established consecutively
because the synchroniza-
tion with the EtherCAT
Master could not be
achieved.
The power supply to the
host controller was inter-
rupted during PDO com-
munications.
Reset the error in the host control-
ler. This event reports an error that
was detected when the power sup-
ply to the host controller was inter-
rupted. It does not indicate that an
error currently exists.
An EtherCAT communica-
tions cable is discon-
nected, broken,
short-circuited, or has a
contact failure in a daisy
chain configuration.
Connect the EtherCAT communica-
tions cable securely. If the cable is
broken, replace it.
An EtherCAT communica-
tions cable is broken,
short-circuited, or has a
contact failure in a ring
topology configuration.
•Set Communications Error Set-
ting (2200 hex) to 2 or more.
• Connect the EtherCAT communi-
cations cable securely. If the
cable is broken, replace it.
Noise Take noise countermeasures if
excessive noise affects the Ether-
CAT communications cable.
Failure of the EtherCAT
physical layer of a Servo
Drive
If this event occurs again after you
performed all corrections shown
above, replace the Servo Drive.
