If the output frequency of the inverter is within the positive and negative amplitudes of the any
frequency reaching detection value, the corresponding digital output becomes ON.
F4.34
Zero current detection level
Range:0.0%~300.0%
Default:5.0%
F4.35
Zero current detection delay time
Range:0.01s~600.00s
Default:0.10s
If the output current of the inverter is equal to or less than the zero current detection level and the
duration exceeds the zero current detection delay time, the corresponding output terminal becomes ON. The
zero current detection is shown in the following figure .
F4.36
Output overcurrent threshold
Range: 0.0%~300.0%
Default:200.0%
F4.37
Output overcurrent detection delay
time
Range:0.00s~600.00s
Default:0.00s
If the output current of the inverter is equal to or higher than the overcurrent threshold and the duration
exceeds the detection delay time, the corresponding output terminal becomes ON. The output overcurrent
detection function is shown in the following Figure .
F4.38
Any current reaching 1
Range:0.0%~300.0%
Default:100.0%
F4.39
Any current reaching 1
amplitude
Range:0.0%~300.0%
Default:0.0%
F4.40
Any current reaching2
Range:0.0%~300.0%
Default:100.0%
F4.41
Any current reaching 2
amplitude
Range:0.0%~300.0%
Default:0.0%
