Bus fault
1. Check whether the CANopen bus
cable used is a standard cable.
2. Check whether the both ends of
the CANopen bus used are
connected to terminal resistors.

the CANopen bus cable used is
strong.
The red light flashes
twice.
Master station: The control of
the errors in a slave station is
not sent after a set period of
time.

does not send a heartbeat
message after a set period of
time.
1. Check whether the CANopen bus
cable used is a standard cable.
2. Check whether the both ends of
the CANopen bus used are
connected to terminal resistors.
The red light is ON. The bus used is off.
1. Check whether the bus cable on
the CANopen network created is
connected correctly.
2. Check whether the serial

Solution
16#A0E0
AH10COPM-5A receives an emergency
message from a slave station.
Use the function block
CANopen_EMCY to read relevant
information.
16#A0E1
The length of a PDO that a slave station
sends is not the same as the length of the
PDO set in the node list.
Set the length of the PDO in the
slave station again, and then
download the setting to
AH10COPM-5A.
