Turning the power on during measuring before LED of the operation panel turns off, it may remain 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 pa-
rameter unit (FR-PU04/FR-PU07). As an alarm display, Pr. 255 bit 2 is turned on and also an alarm is out-
put 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 meas-
uring" = 1), the DC voltage is applied to the motor for 1 s 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.
