When the output frequency is within the range of the positive and negative detection amplitude of any detected
frequency, the multi-function output terminal (function 26/27) outputs an ON signal.
S3100A provides two sets of arbitrary arrival frequency detection parameters, set frequency value and frequency
detection range respectively. Figure 5-21 is a schematic diagram of this function.

When the output current of the inverter is less than or equal to the zero current detection level and the duration
exceeds the zero current detection delay time, the multi-function output terminal (function 34) of the inverter
outputs an ON signal. Figure 5-22 is a schematic diagram of zero current detection.
