LIFE OF INVERTER PARTS
(1) Life warning display and signal output (Y90 signal, Pr.255)
• Whether the parts of the control circuit capacitor, main circuit capacitor, cooling fan, and
inrush current limit circuit have reached the life warning output level or not, can be checked
with E700 (Pr.255) and the life alarm signal (Y90).

(decimal)
• The life alarm signal (Y90) turns ON when any of the control circuit capacitor, main circuit
capacitor, cooling fan, or inrush current limit circuit reaches the life warning output level.
• For the terminal used for the Y90 signal, set "90" (positive logic) or "190" (negative logic) in
any of M400 to M406 (Pr.190 to Pr.196) (output terminal function selection).
Remark
Changing the terminal assignment by using M400 to M406 (Pr.190 to Pr.196) (output
terminal function selection) may affect the other functions. Set parameters after confirming
the function of each terminal.

When using an option (FR-A8AY, FR-A8AR, FR-A8NC), the life can be output
separately to the Control circuit capacitor life (Y86) signal, Main circuit capacitor
life (Y87) signal, Cooling fan life (Y88) signal, and Inrush current limit circuit life
(Y89) signal.
