Turning the power on during measuring before LED of the operation panel turns off, it may re-
main in "measuring" (Pr. 259 = 2) status. In such case, carry out operation from step
.
Cooling fan life display
The cooling fan speed of 40% or less is detected and "FN" is displayed on the operation panel
and parameter unit (FR-PU04/FR-PU07). As an alarm display, Pr. 255 bit 2 is turned on and also
an alarm is output to the Y90 signal.
NOTE
For the accurate life measuring of the main circuit capacitor, perform after more than 3 hrs
passed since the turn off of the power as it is affected by the capacitor temperature.

WARNING:
When measuring the main circuit capacitor capacity (Pr. 259 "Main circuit capacitor
life measuring" = 1), the DC voltage is applied to the motor for 1s at powering off. Never
touch the motor terminal, etc. right after powering off to prevent an electric shock.
NOTE
When the inverter is mounted with two or more cooling fans, "FN" is displayed with one or
more fans with speed of 50% or less.
