Description of Fault Codes
‑88‑
● ED02.0: Modbus communication timeout
Cause
Confirming Method
Solution
Modbus communication
timeout
Increase the value of H0E.83.
Determine the Modbus
access cycle by frame grab.
● ED03.0: CANLink communication failure
Cause
Confirming Method
Solution
The master is offline.
1. Increase the heartbeat
threshold of the master
station.
2. Check the wiring.
Capture frames to ensure
that the master station is
online.
● ED04.0: CANopen communication timeout
Cause
Confirming Method
Solution
The slave reaches the time
configured by the consumer
or the node guarding time.
Check whether the
heartbeat frame cycle of the
host controller is normal by
capturing frames.
Check whether all CAN
nodes are online, or check
the CANopen configuration,
reset the node or
communication.
● ED05.0: CANopen communication initialized
Cause
Confirming Method
Solution
After the motor is enabled,
errors such as slave offline,
heartbeat abnormal, load
ratio too high, data frame
loss, and false master reset
occurred when NMT changes
to the initialization state.
Check whether the reset
frame is received during
operation by capturing
frames.
Reset the NMT node. When
changing the NMT, disable
the output stage.
1. Use shielded cables to
prevent interference.
2. Ground the servo drive
properly.
3. Ensure the load rate is
proper.
4. If asynchronous
transmission is
configured, ensure the
suppression time is set
properly.
5. Ensure no false reset
frame is triggered by the
host controller.
6. Ensure the termination
resistor is installed.
● ED08.0: CANopen bus PDO transmission length error
