7-4 Alarm list
A list of alarms and warnings is shown.
AL: Present alarm/warning display
The driver shows the code number of the present alarm/warning.
If multiple alarms (warnings) are output, all alarm (warning) codes are shown one by one at an interval
of approx. 500 ms. If no alarm (warning) is present, [--] is shown.
Even when an alarm (warning) is output, you can still switch to a mode other than the alarm mode and
display various parameters and status data.
The relationship of displayed code numbers and alarms/warnings is shown below.
For details, refer to [Chapter 11 Troubleshooting].
