0035 Synchroniza-
tion Cycle 
Setting Error
When the DC mode was 
established, the cycle time 
was set to the inoperable 
value.
In the variable PDO map-
ping, the maximum num-
ber of objects you can 
map is specified as fol-
lows: 6 for both RxPDO 
and TxPDO for the com-
munication period of 125 
µs, 10 for both RxPDO 
and TxPDO for other com-
munication periods. An 
error occurs if you map a 
larger number of objects 
than that specified above.
This error is also detected 
in the following case: the 
cycle time is an integral 
multiple of 125 µs and is 
not 10 ms or lower.
The variable PDO map-
ping is used, and the num-
ber of objects is more than 
the maximum number of 
mapped objects for the 
cycle time.
Set the number of objects to a value 
smaller than the maximum number 
of mapped objects for the cycle 
time.
The cycle time setting is 
incorrect.
Correct the cycle time setting.
0050 ESC Error An error occurred in the 
EtherCAT slave communi-
cations controller.
Error access from the 
non-OMRON EtherCAT 
master
Please contact the manufacturer of 
EtherCAT master.
0051 Error of the EtherCAT 
slave communications 
controller or false detec-
tion
If this event occurs repeatedly after 
you cycled the power supply, the 
EtherCAT slave communications 
controller is faulty. Replace the 
Servo Drive.
0061 Node Address 
Updated
The node address is changed to a value of the ID 
switches.
Check the node address value. 
Set a correct value if it is wrong.
The node address is changed from a set value in Sys-
mac Studio to a value of the ID switches.
