AL111 Buffer overflow occurs when receiving CANopen SDO
Trigger condition
and cause
SDO Rx Buffer overflows (receives more than two SDOs within 1 ms).
Checking method
and corrective action
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 cause
PDO Rx Buffer overflows (receives more than two PDOs of COBID within 1 ms).
Checking method
and corrective action
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 accessing CANopen PDO
Trigger condition
and cause
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 method
and corrective action
1.
Check if the object’s index number for PDO mapping of the controller is
correct.
2.
If the index number is correct, it means this specified object is not supported
by the servo drive. Check if it is necessary to use this object or if you can
substitute it with a different object.
How to clear the
alarm?
NMT: reset node or 0x6040 fault reset.
AL122 Object’s sub-index does not exist when accessing CANopen PDO
Trigger condition
and cause
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 method
and corrective action
1.
Check if the object’s sub-index number for PDO mapping of the controller is
correct.
2.
If the sub-index number is correct, it means this specified object is not
supported by the servo drive. Check if it is necessary to use this object or
if you can substitute it with a different object.
How to clear the
alarm?
NMT: reset node or 0x6040 fault reset.
