Capacitor Life Alarm (Pr. 503, Pr. 504) - Mitsubishi Electric FR-A520-0.4K Instruction Manual

4.2.65 Capacitor life alarm (Pr. 503, Pr. 504)

Pr. 503 "capacitor life timer"
Pr. 504 "capacitor life alarm output setting time"
When the cumulative operation time of the inverter has elapsed the time set in Pr. 504 "capacitor life alarm
output set time", the capacitor life alarm output signal "Y95" is output to inform that it is time for replacement
(Note 1) of the smoothing capacitor in the main circuit of the inverter.

The life of electrolytic capacitor is about ten years (87600 hours) in the average yearly ambient temperature
of 40°C. (Note 2)
The life of electrolytic capacitor decreases to half if the ambient temperature increases by 10°C and doubles
if decreases by 10°C. Please note this as reference when setting the time.
For example, when the average yearly ambient temperature is 50°C, set "438" (43800 hours) in Pr. 504
Note: 1. For replacement of the capacitor, contact the nearest Mitsubishi FA center.
2. The estimated life time (87600 hours) of the capacitor differs according to the environmental
conditions (ambient temperature, conditions, etc.) of the inverter.
