in the Warning Hold Selection (3759 hex). Life Expectancy Warning is fixed to Latch mode only.
*2
Set the Warning Output Selection 1 (3440 hex) to the warning type to output to Warning Output 1 (WARN1),
and set the Warning Output Selection 2 (3441 hex) to the warning type to output to the Warning Output 2
(WARN2). If you set these objects to 0, all warning types are output.
*3 Detection of general warnings can be masked with the Warning Mask Setting (3638 hex) and detection of
EtherCAT communications-related warnings can be masked with the Communications Control (3800 hex).
When the bit is set to 1, the warning detection is masked.
