Life diagnosis functionVer.UP

Monitoring functions for predictive maintenance and planned maintenance are enhanced.

The life of the following parts can be diagnosed.

Main circuit capacitor
Cooling fan
Control circuit capacitor
Inrush current limit circuit
Fault contact relay
Main circuit elements

* The function is conceptually illustrated. It is not the actual layout.

Parts service life data is displayed in a dedicated window in FR Configurator2. An alert icon is shown in the parts life alarm field for the parts recommended for replacement. This can be used as a guideline to replace long life parts.

TipsProcedure for easy diagnosis check (main circuit capacitor life diagnosis)

Check that the motor is connected and at a stop, then set "1" in Pr.259.

Turn OFF the power.
The inverter applies DC voltage to measure the capacitor capacity while the inverter power is OFF.

After confirming that the LED of the inverter is OFF, power ON again.

If the setting value of Pr.259 becomes "3", it means that the measurement is completed. When Pr.258 is read, the deterioration degree is displayed as a percentage, considering the capacitor capacity at shipment as 100%.
Regard 85% or less as the end of part life.

Intervene before abnormally performing equipment leads to costly failures

Load characteristics measurement functionNEW

The system stores normal speed-torque characteristics, comparing live data to detect mechanical faults like filter clogging. This enables the inverter to issue warnings or shut down, proactively preventing costly system damage.
