Learning Protection Features
2 Check the value displayed at Pr-63 (CAP Diag Level). If the value displayed at Pr-63 is smaller
than the value set at Pr-62 (CAP. Level 1), a capacitor replacement warning (CAP Exchange)
will occur.
3 While the capacitor replacement warning continues, confirm that the first bit at Pr-89
(Inverter State) is set.
4 Set Pr-62 to 0.0%. The capacitor replacement warning (CAP Exchange) will be released.
5 Set Pr-61 to 3 (CAP. Init) and make sure that the value displayed at Pr-63has changed to 0.0%.
Lifetime diagnosis for fans
Enter the Pr-87(Fan exchange warning level) code (%). After the selected usage (%) is reached (out
of 50,000 hours), the fan exchange warning message will appear in the multi-functional output or
keypad.
The total fan usage level (%) appears at Pr-86. When exchanging fans, you may initialize the
accumulated value to 0 by setting the CNF-75 (Initializing accumulated time for cooling fans) to 1.

the inverter stops output and a low voltage trip
occurs.
