Appendix 2 Error Information & Solution
Error Description Solutions
Download the data again from XG5000 and place requests for
A/S it is occurs repeatedly after re-execution.
It failed to change to EtherCAT INIT state.
Check the communication cable status and slave operation
status (power-on and error occurrence). And check whether the
communication cable is exposed to noise.
0F06 3846 It is EtherCAT INIT state initialization (DC_INIT)
error.
Check the communication cable connection status and slave
operation status(power-on and error occurrence). And check
whether the communication cable is exposed to noise.
There is no EtherCAT slave connected to the
controller.
Check whether the communication cable between the controller
and the EtherCAT slave is properly installed, the power is
normally applied to the EtherCAT slave, or the communication
cable is exposed to noise if there is a slave connected to the
It exceeded the maximum number of connected
slaves.
Make sure that there are not more than 64 EtherCAT slaves
connected to the controller.
There is a difference in node ID and EtherCAT
parameter settings of the EtherCAT slave.
Check whether the order of the network cable connection
between the controller and the EtherCAT slaves matches the
EtherCAT parameter settings.
There is an error in setting node ID of the
EtherCAT slave.
Check whether there are duplicate node IDs or errors in settings.
0F10 3856 It failed to change to EtherCAT PREOP stage. Check the communication cable connection status and slave
operation status (power-on and error occurrence). And check
whether the communication cable is exposed to noise.
There is no slave setting data of EtherCAT
parameter.
Set the slave of the EtherCAT parameter using XG5000, and
then send the EtherCAT parameter to the controller.
The slave setting data of the EtherCAT parameter
and the connected slave are different.
Set the slave setting of the EtherCAT parameter to match the
actually connected slave information. The slave of the EtherCAT
parameter can be set automatically using the 'EtherCAT Slave
Auto Connection' function in XG5000.
0F20 3872 It failed to change to EtherCAT SAFEOP state. Check the communication cable connection status and slave
operation status (power-on and error occurrence). And check
whether the communication cable is exposed to noise.
It failed to change to EtherCAT OP state.
Check the communication cable connection status and slave
operation status (power-on and error occurrence). And check
whether the communication cable is exposed to noise.
0F40 3904 It failed to change from EtherCAT OP state to INIT
state.
Check the communication cable connection status and slave
operation status (power-on and error occurrence). And check
whether the communication cable is exposed to noise.
There is no response in a communication
connection state.
Check the communication cable connection status and slave
operation status (power-on and error occurrence). And check
whether the communication cable is exposed to noise.
Periodic communication error occurred.
(Communication error that exceeds the periodic
communication timeout count of master
Check whether servo power is off during communication,
communication cable is properly installed, or communication
cable is exposed to noise.
