Mitsubishi Electric FR-A820-00046 (0.4K) Instruction Manual page 343

*2 The setting is available only for standard models and IP55 compatible models.
 Life alarm display and signal output (Y90 signal, Pr.255)
• In the life diagnosis of the main circuit capacitor, the alarm signal (Y90) is not output unless measurement by turning OFF the
power supply is performed.
• Whether or not the parts of the control circuit capacitor, main circuit capacitor, cooling fan, inrush current limit circuit or
internal air circulation fans have reached the life alarm output level can be checked with Pr.255 Life alarm status display
and the Life alarm (Y90) signal. (Internal air circulation fans are equipped with IP55 compatible models.)

○: With warnings, ×: Without warnings
• The Life alarm (Y90) signal 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 level.
• 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).
NOTE
• When using an option (FR-A8AY, FR-A8AR, FR-A8NC, FR-A8NCE), 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.
• 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.
