4.2.38 Output current detection function (Pr. 150, Pr. 151)
Pr. 150 "output current detection level"
Pr. 151 "output current detection period"
!
If the output current remains higher than the Pr. 150 setting during inverter operation
for longer than the time set in Pr. 151, the output current detection signal (Y12) is
output from the inverter's open collector output terminal.
(Use any of Pr. 190 to Pr. 192 to assign the terminal used for Y12 signal output.)

Refer to the following list and set the parameters:
Parameter

Description
150
Set the output current detection level.
100% is the rated inverter current.
151
Set the output current detection time. Set a period of time from when the
output current rises to or above the Pr. 150 setting to when the output
current detection signal (Y12) is output.
Note: 1. The output current detection signal is held on for about 100ms (at least) if it
switches on once when the output current rises to or above the preset
detection level.
2. This function is also valid during execution of offline auto tuning.
3. When the terminal functions are changed using Pr. 190 to Pr. 192, the other
functions may be affected. Confirm the functions of the corresponding
terminals before making settings.
