: With warnings, ×: Without warnings

● The life alarm signal (Y90) turns ON when any of the control circuit capacitor, main circuit capacitor,

cooling fan, inrush current limit circuit, or internal air circulation fans reaches the life alarm output

● For the terminal used for the Y90 signal, set "90" (positive logic) or "190" (negative logic) in any of

Pr. 190 to Pr. 196 (output terminal function selection).

When using an option (FR-A8AY, FR-A8AR, FR-A8NC, FR-A8NCE), the life can be output separately

to the control circuit capacitor life signal (Y86), main circuit capacitor life signal (Y87), cooling fan

life signal (Y88), and inrush current limit circuit life signal (Y89).

Changing the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection)

may affect the other functions. Set parameters after confirming the function of each terminal.

Life display of the inrush current limit circuit (Pr. 256)

(Standard models and IP55 compatible models)

● The life of the inrush current limit circuit (relay, contactor and inrush resistor) is displayed in Pr. 256.

● The number of contact (relay, contactor, thyristor) ON times is counted, and it is counted down

from 100% (0 time) every 1%/10,000 times. As soon as 10% (900,000 times) is reached, Pr. 255 bit

3 is turned ON and also a warning is output to the Y90 signal.
