Communication Type:
AL111 Buffer overflow occurs when receiving CANopen SDO
Trigger condition
and causes
SDO Rx Buffer overflow (receives more than two SDOs within 1 ms).
Checking methods
and corrective
actions
Check if the servo drive (master) receives or sends more than one SDO
within 1 ms.
How to clear the
alarm?
NMT: reset node or 0x6040 (fault reset).
AL112 Buffer overflow occurs when receiving CANopen PDO
Trigger condition
and causes
PDO Rx Buffer overflow (receives more than two PDOs of COBID within
1 ms)
Checking methods
and corrective
actions
Check if the servo drive (master) receives or sends more than one PDO of
COBID within 1 ms.
How to clear the
alarm?
NMT: reset node or 0x6040 (fault reset).
AL121 Object’s index does not exist when CANopen PDO is received
Trigger condition
and causes
When the servo drive receives the PDO from the controller, the specified
object’s index number is incorrect so that the servo drive cannot identify it.
Checking methods
and corrective
actions
1. Check if the object’s index for PDO mapping for the controller is correct.
2. If the index number is correct, it means this specified object is not
supported by the servo drive. Please check if it is necessary to use this
object, or if you can substitute a different object.
How to clear the
alarm?
NMT: reset node or 0x6040 (Fault Reset)..
AL122 Object’s sub-index does not exist when CANopen PDO is received
Trigger condition
and causes
When the servo drive receives the PDO from the controller, the specified
object’s sub-index number is incorrect so that the servo drive cannot
identify it.
Checking methods
and corrective
actions
1. Check if the object’s sub-index for PDO mapping for the controller is
correct.
2. If the sub-index number is correct, it means this specified object is not
supported by the servo drive. Please check if it is necessary to use this
object, or if you can substitute a different object.
How to clear the
alarm?
NMT: reset node or 0x6040 (fault reset.).
