Trigger condition

and cause

 When the servo drive receives the PDO from the controller, the specified object’s sub-index number is incorrect, so 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, 0x6040 fault reset, or DI.ARST.
