Revision December, 2017
SDO Rx Buffer overflow (receives more than two SDOs within 1 ms).
Check if the servo drive (master) receives or sends more than one SDO
within 1 ms.
NMT: reset node or 0x6040 (fault reset).
PDO Rx Buffer overflow (receives more than two PDOs of COBID within
1 ms)
Check if the servo drive (master) receives or sends more than one PDO of
COBID within 1 ms.
NMT: reset node or 0x6040 (fault reset).
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.
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.
NMT: reset node or 0x6040 (Fault Reset)..
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.
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.
NMT: reset node or 0x6040 (fault reset.).
