5.4.16 Inverter parts life display
The degree of deterioration of the control circuit capacitor, main circuit capacitor, cooling fan, inrush current limit circuit, and
relay contacts of terminals A, B, and C can be diagnosed on the monitor.
When a part approaches the end of its life, an alarm can be output by self diagnosis to prevent a fault.
(Note that the life diagnosis of this function should be used as a guideline only, because with the exception of the main circuit
capacitor, the life values are theoretical calculations.)
*1 The setting range (read-only) differs depending on the inverter model (standard model or separate converter type).
*2 The setting is available only for standard models.
Pr. Name Initial value Setting range Description
255
E700
Life alarm status display 0
(0 to 255)
*1
Displays whether or not the parts of the control
circuit capacitor, main circuit capacitor, cooling fan,
and inrush current limit circuit have reached the life
alarm output level. Read-only.
256
E701
*2
Inrush current limit circuit life
display
100% (0 to 100%) Displays the deterioration degree of the inrush
current limit circuit. Read-only.
257
E702
Control circuit capacitor life display 100% (0 to 100%) Displays the deterioration degree of the control
circuit capacitor. Read-only.
258
E703
*2
Main circuit capacitor life display 100% (0 to 100%) Displays the deterioration degree of the main
circuit capacitor. Read-only.
The value measured by Pr.259 is displayed.
259
E704
*2
Main circuit capacitor life measuring 0 0, 1(2, 3, 8, 9) Setting "1" and turning the power supply OFF
starts the measurement of the main circuit
capacitor life.
If the setting value of Pr.259 becomes "3" after
turning the power supply ON again, it means that
the measurement is completed. The deterioration
degree is read to Pr.258.
11(12, 13, 18,
19)
When "11" is set, turning OFF the power supply
starts the measurement of the main circuit
capacitor life.
If the setting value of Pr.259 becomes "13" after
turning the power supply ON again, it means that
the measurement is completed. The degree of
deterioration is read to Pr.258.
506
E705
*2
Display estimated main circuit
capacitor residual life
100% (0 to 100%) Displays the estimated residual life of the main
circuit capacitor. Read-only.
507
E706
Display/reset ABC1 relay contact life 100% 0 to 100% Displays the degree of deterioration of the relay
contacts of terminals A1, B1, and C1.
508
E707
Display/reset ABC2 relay contact life 100% 0 to 100% Displays the degree of deterioration of the relay
contacts of terminals A2, B2, and C2.
