10-1-4 Warning Display
If the set parameter contradicts other set value, the inverter will display a warning with the program LED
blinking.
The table below lists the warning displays and their display conditions. If the warning display appears,
change the parameter setting according to this table. (Inputting the RUN command does not rewrite the
correct parameter value automatically.)
The latest warning display is stored in the parameter d090.
