Main Sub
83 1 EtherCAT
state
change
error
Occurs
during
operation.
A communications state change
command was received for which the
current communications state could
not be changed.
Check the specifications of the
communications state change
command for the host controller.
2 EtherCAT
illegal state
change
error
Occurs
during
operation.
An undefined communications state
change command was received.
Check the specifications of the
communications state change
command for the host controller.
3 Communi-
cations syn-
chronization
error
*1
Occurs
during
operation.
The number of consecutive errors in
receiving data during the
communication sync time exceeded
the value specified for the
Communications Error Setting (2200
hex).
• Connect the EtherCAT
communications cable correctly.
• Check to see if the EtherCAT
communications cable is exposed
to excessive noise.
• Check that the host controller
completed communications before
a interruption is generated in the
synchronous cycle (SYNC0 cycle).
4 Sync Error Occurs
during
operation.
Control PCB error Replace the Servo Drive.
5 Sync
Manager
WDT Error
Occurs
during
operation.
PDO communications were stopped
for more than the specified period of
time.
• Check the operation of the host
controller.
• Connect the EtherCAT
communications cable correctly.
88 0 Node
address
setting error
Occurs
when the
power
supply is
turned ON.
The node address that was read from
the rotary switches was not
between 00 and 99.
• Turn OFF the power supply, then
turn it ON again.
• Replace the Servo Drive.
1 ESC
initialization
error
Occurs
when the
power
supply is
turned ON.
Control PCB error • Turn OFF the power supply, then
turn it ON again.
• Replace the Servo Drive.
2
Interruptions
Error
Occurs
when the
power
supply is
turned ON.
Control PCB error • Turn OFF the power supply, then
turn it ON again.
• Replace the Servo Drive.
3SII
verification
error
Occurs
when the
power
supply is
turned ON.
Control PCB error • Turn OFF the power supply, then
turn it ON again.
• Replace the Servo Drive.
*1 This warning can also occur when the power supply to the master is turned OFF while EtherCAT communications are
established. Therefore, if you turn OFF the power supply to the master and then immediately turn OFF the power supply
to the G5-series Servo Drive, an event may be saved in the error history.
