Prolonged service life and improved life judgment function
Designed life 10 years
For the various consumable parts inside the inverter, their designed lives have been extended to 10 years, which also extended the equipment maintenance cycles.
| Consumable part |
Designed life |
| Main circuit capacitor |
10 years |
| Electrolytic capacitor on PCB |
10 years |
| Cooling fan |
10 years |
The conditions used for the calculation of the parts lives are:
an ambient air temperature of 40°C and under the load rate of 100% (HD spec) or 80% (LD spec)

The design lives are the calculated values and not the guaranteed ones.
Full support of life warnings
The inverter is equipped with the functions for facilitating the maintenance of the equipment.
| Item |
Purpose |
| Cumulative inverter run time (h) |
Displays the total run time of the inverter. |
| Number of inverter startups |
Displays the number of times the inverter has started the equipment.
Example of use:
This data indicates the time to replace the equipment parts (such as a timing belt) operating under the normal load. |
| Equipment maintenance warning Cumulative run time (h) Number of startups |
By inputting the signal for operation with the commercial power supply, the time without the inverter operation time can also be measured.
This makes it possible to manage the total run time of the equipment and the number of startups. Such data is usable for preparing the maintenance schedule. |
| Display of inverter life warning |
The displayed contents include:
main circuit capacitor capacity, total run time of the cooling fan (with ON/OFF compensation), total run time of the electrolytic capacitor on the printed circuit board, and total run time of the inverter. |
