Life alarm display and signal output (Y90 signal, Pr.255)
POINTPOINT
• 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 signal (Y90). (Internal air circulation fans are equipped with IP55 compatible models.)
: 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 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 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.
