4.2.44 Output current detection function (Pr. 150, Pr. 151)
Pr. 150 "output current detection level"
Pr. 151 "output current detection period"
zIf 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. 195 to assign the terminal used for Y12 signal output.)
<Setting>
Refer to the following list and set the parameters:

150 150% 0 to 200.0%
151 0s 0 to 10 s
Parameter Number Description
150
Set the output current detection level.
100% is the rated inverter current.
151
Set the output current detection period. 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. Once switched on, the output current detection signal is held on for at least 100ms.
2. This function is also valid during execution of the online or offline auto tuning.
3. When the terminal functions are changed using Pr. 190 to Pr. 195, the other functions may be
affected. Confirm the functions of the corresponding terminals before making settings.
