Life prediction function
The inverter has the life prediction function for some parts which measures the discharging time or counts the voltage
applied time, etc. The function allows you to monitor the current lifetime state on the LED monitor and judge whether
those parts are approaching the end of their service life.
The life prediction function can also issue early warning signals if the lifetime alarm command
LIFE is assigned to any
of the digital output terminals by any of E20 through E24 and E27.
For details, refer to Chapter 7, "MAINTENANCE AND INSPECTION."
