10-2 Warning List
The warning function outputs a warning signal and notifies state such as an overload before activation
of a protective function.
Set what types of warning you want the Servo Drive to output in Warning Output Selection 1 (Pn440)
and Warning Output Selection 2 (Pn441).
Precautions for Correct Use
Precautions for Correct Use
You will be brought to the state before the occurrence of the warning automatically after recovery
from the error condition. However, the warning state will be retained during the time period set in
Warning Latch Hold Time Selection (Pn627). To clear the warning state before the latch hold
time expires, follow a similar procedure as you do when clearing an alarm.
*1
The “
√
” fields can be set to 1 to 10 s in Warning Latch Hold Time Selection (Pn627) or to no time limit.
However, the battery warning is fixed to no time limit.
*2
Select the types of warning to be output from Warning Output 1 (WARN1) and Warning Output 2 (WARN2) in
Warning Output Selection 1 (Pn440) and Warning Output Selection 2 (Pn441). If you set these parameters to
0, all warning types will be output. Do not set other values not listed above.
*3
Each warning detection can be masked by Warning Mask Setting (Pn638). The bit corresponding to each
warning is shown in the table above.
When the bit is set to 1, the warning detection is masked.
