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 EM11 provides two groups of any frequency reaching detection parameters, including frequency
detection value and detection amplitude, as shown in the following figure.

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.

If the output current of the frequency inverter is equal to or higher than the over current threshold and the
duration exceeds the detection delay time, the corresponding DO becomes ON. The output over current
detection function is shown in the following figure.
