83 03 Communica-
tions Syn-
chronization
Error Communications were
not established consec-
utively because the syn-
chronization with the
EtherCAT Master could
not be achieved. The power supply to the
host controller was
interrupted during PDO
communications. 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 communi-
cations 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 communi-
cations 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.
04 Synchroniza-
tion Error A signal for synchro-
nous 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.
05 Sync Man-
ager WDT
Error PDO communications
were interrupted for the
allowable period or lon-
ger. An EtherCAT communi-
cations cable is discon-
nected, loose, broken,
or has a contact failure. Connect the EtherCAT communica-
tions cable securely. If the cable is
broken, replace it.
Host controller error Check the operation of the host
controller. Take appropriate
countermeasures if there is a prob-
lem.
06 Bootstrap
State Transi-
tion Request
Error The state transition to unsupported Bootstrap was
requested. Check the EtherCAT master setting
so that the EtherCAT master does
not request the transition to Boot-
strap.
87 00 Error Stop
Input The Error Stop Input
(ESTP) is active. The Error Stop Input
(ESTP) was input. Remove the cause of Error Stop
Input (ESTP).
The Error Stop Input
(ESTP) is incorrectly
wired. Correct the wiring if the Error Stop
Input (ESTP) is incorrectly wired.
