Cause
Confirming Method
Solution
The length of the content
transmitted by PDO is
inconsistent with the
configured mapping length.
Check whether the PDO
transmission length is
consistent with the
configuration by capturing
frames.
Re‑configure the PDO and
reset the node or
communication.
● ED11.0: CANopen sync period error too large
Cause
Confirming Method
Solution
The SYNC period error
exceeds the setpoint
Collect the synchronization
signal using the software
tool and calculate whether
the cycle is higher than the
fault threshold.
Check the settings of
60C2.01h and 60C2.02h and
ensure the synchronization
period is set properly.
Ensure the synchronization
period of the host controller
is set correctly and
consistent with the setting
of 60C2h.
Check the wiring between
the slave and the master.
● EE08.0: Synchronization lost
