These signals output alarm codes to indicate the type of alarm detected
by the servo amplifier. Use these signals to display alarm codes at the
host controller. See 9.2.3 Alarm Display Table for more on the
relationship between alarm display and alarm code output.
When a servo alarm (ALM) occurs, eliminate the cause of the alarm and
set the following /ALM-RST input signal to high level (ON) to reset the
alarm.
