Output current detection (Y12 signal, Pr. 150, Pr. 151, Pr. 166, Pr. 167)
● The output current detection function can be used for purposes such as overtorque detection.
● If the output during inverter running remains higher than the Pr. 150 setting for the time set in
Pr. 151 or longer, the Output current detection (Y12) signal is output from the inverter's open
collector or relay output terminal.
● When the Y12 signal turns ON, the ON state is retained for the time set in Pr. 166.
● When Pr. 166 = "9999", the ON state is retained until the next start.
● Setting Pr. 167 = "1" while the Y12 signal is ON does not cause E.CDO. The Pr. 167 setting becomes
valid after the Y12 signal is turned OFF.
● For the Y12 signal, set "12 (positive logic) or 112 (negative logic)" in any of Pr. 190 to Pr. 196 (output
terminal function selection) to assign the function to the output terminal.

Setting range Description
Set the output current detection level.
150%
0 to 220%
100% is the rated inverter current.
Set the output current detection time. Set the
time from when the output current reaches the
0s
0 to 10 s
setting or higher until the output current
detection (Y12) signal is output.
Set the zero current detection level.
5%
0 to 220%
The rated inverter current is regarded as 100%.
Set the time from when the output current
0.5s
0 to 10 s
drops to the Pr. 152 setting or lower until the
zero current detection (Y13) signal is output.
Set the retention time when the Y12 signal is
0 to 10 s
ON.
0.1s
Retain the Y12 signal ON status. The signal is
9999
turned OFF at the next start.
Select the operation at turn on of the Y12 and
