b4-29
Any frequency reaching detection value 2
Default
50.00 Hz
Setting Range
0.00 Hz ~ maximum frequency
b4-30
Any frequency reaching detection amplitude 2
Default
0.0%
Setting Range
0.0%~100.0% (maximum frequency)
If the output frequency of the frequency inverter is within the positive and negative amplitudes of the any frequency
reaching detection value, the corresponding DO becomes ON.
The EM12 provides two groups of any frequency reaching detection parameters, includingfrequency detection value
and detection amplitude, as shown in the following figure.

b4-31
Zero current detection level
Default
5.0%
Setting Range
0.0%~100.0% (rated motor current)
b4-32
Zero current detection delay time
Default
0.10s
Setting Range
0.00s~600.00s
If the output current of the frequency inverter is equal to or less than the zero current detection level and the duration
exceeds the zero current detection delay time, the corresponding DO becomes ON. The zero current detection is
shown in the following figure.
