*1 Set the Warning Output Selection (3440 hex) to the warning type to output to Warning Output 1 (WARN1), and
set Warning Output Selection 2 (3441 hex) to the warning type to output to Warning Output 2 (WARN2). If you
set these objects to 0, all warning types are output.
*2 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). The
warning detection is masked when you set the corresponding bit to 1.
*3 This warning can also occur when the power supply to the master is turned OFF while EtherCAT
communications are established. Therefore, if you turn OFF the power supply to the master and then
immediately turn OFF the power supply to the G5-series Servo Drive, an event may be saved in the error
history.
