When the inverter's output frequency randomly reaches the range of the detected
value(positive or negative), the multi-function DO will output ON signal.
PI9000 provides two groups of parameter to set frequency value and frequency
detection range. The above figure is the schematic diagram of the function.

When the inverter's output current is less than or equal to zero current detection level
and lasts for longer than the delay time of zero-current detection, the inverter's multifunction
DO will output ON signal. The figure is the schematic diagram of zero current detection.
