7.2.1 Overview
The alarm record function can record up to 10 alarms that have occurred in the servo unit. You can
confirm the alarm code and time that occurs. (measurement of the duration of the control power
supply and the main circuit power supply in 100ms increments, and the function to display the total
operation time in the event of an alarm, It can be measured continuously for about 31 years if it is
operated 24 hours per day and 365 days per year).
