Inverter Output Limiting (IOL, IOL2)
This signal is output when the inverter is performing one of the limitation operations described below.
(Minimum output signal width 100 ms) The signal is output when the limitation operation in “22: IOL2
(Inverter output limiting with delay)” continues for 20 ms or longer
.

The OFF delay becomes the time obtained by adding 0.1 s to Output Terminal [DO1] OFF Delay Time
(H310), Output Terminal [DO2] OFF Delay Time (H312) and Output T

Time (H314).
• When the IOL signal or the ILO2 signal is ON, the output frequency of the inverter is automatically
controlled by the limitation processes described above, and thus, the set frequency may not be ach-
ieved.

Low-To-Moderate Voltage Detection (U-EDC)
This signal turns ON when the Main Circuit DC Voltage becomes equal to or below Main Circuit DC
Voltage low-voltage detection level (E76), and turns OFF when it becomes above the Main Circuit DC
Voltage low-voltage detection level (E76).
