Main circuit capacitor residual-life estimation function
Even when the power supply cannot be turned OFF, the remaining life of the main circuit capacitor can be estimated
without stopping the operation. Note that the remaining life of the main circuit capacitor estimated by this function is
theoretical, and should be used as a guideline only.

Valid values (read only) for separated converter type inverters are "0, 1, 4, and 5". The setting range (reading only) for IP55 compatible
modes is "0 to 63".
*2
The setting is available only for standard models and IP55 compatible models.
 Display estimated main circuit capacitor residual life (Pr.506)
• The estimated residual life of the main circuit capacitor is displayed in Pr.506.
• The remaining life of the main circuit capacitor is calculated from the energization time and the inverter output power (100% =
Start of service life). When the remaining life of the main circuit capacitor falls below 10%, bit 5 of Pr.255 Life alarm status
display turns ON and a warning is output by the Y90 signal.
 Life alarm display and signal output (Y90 signal, Pr.255)
• Power no longer needs to be turned OFF for the warning signal (Y90) to be output when using the main circuit
residual-life estimation function.
• 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.)
