3.8 E-CapLife T ab
T his tab shows the expected remaining life of GXE.
T his function is effective only when GXE is used as the placement method of "MountA".
T he remaining life expectancy is calculated by calculating the remaining service life years
from the "E - Cap Life" and "cumulative operating time" by a linear expression.
T his function is a just reference data, it does not guarantee the product life.

Overview
1
E-Cap Life
Displays the predicted remaining life of electrolytic capacitor relative to Lo as a percentage.
E-Cap Life is also displayed on the main screen.
T he communication register specification returns the remaining life [hour]
when the electrolytic capacitor is at 105
℃
.
However, in Graphical screen mode, the remaining life is indicated by [%].
T he denominator is the initial value.
T he initial value is different for each voltage model, but it is automatically discriminated.
Initial value 24V
8000
[hour]
48V
10000
[hour]
2
Maximum Expected
T he maximum expected life is 15 years after delivery.
Life
Because of deterioration of sealing rubber of electrolytic capacitor.
3
Remaining life span
T he remaining life span is the time to reach 0% assuming that E-Cap Life decreases
in the primary equation.
T he value input from the use environment input column is added to the predicted
lifespan years.
T he display limit is 15 years.
4
Usage environment
T his is a schedule input field using GXE.
input field
You can enter the number of working days per week, the number of working hours per day.
As the default value, a value assuming 24 hours 365 days operation is entered.
5
User device
T his is the time that GXE cumulative operation time was reflected
operation time
for the usage environment input field.
6
Update button
When you click the UPDATE button, it is updated based on the value entered in the usage
environment input field.
