12 Troubleshooting and Maintenance
12 - 6
G5-series Linear Motors/Servo Drives With Built-in EtherCAT Communications
There are two types of warnings: general warnings and warnings related to EtherCAT communications.
*1
The check mark symbol (
3
) in the above table means that you can switch between the “Do not hold (for 1 s)”
and “Hold” warning statuses in the Warning Hold Selection (3759 hex). Life Expectancy Warning is fixed to
“Hold.”
*2
Set the Warning Output Selection 1 (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.
*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).
The corresponding bits are shown in the table. When the bit is set to “1,” the warning detection is masked.
Precautions for Correct Use
Precautions for Correct Use
•
Do not use any settings for Error Output Selection 1 (3440 hex) and Error Output Selection 2
(3441 hex) other than those given in the above table.
•
You can clear these warnings by executing the error rest command. The command does clear
the warning even if the cause of the warning is not removed, but the same warning will occur
again.
