Figure 5-24:Zero current detection delay time
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.

Figure 5-25:Schematic diagram of Zero current
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.

When the inverter's output current randomly reaches the range of the current detection
width(positive or negative), the inverter multifunction DO will output ON signal.
PI160 provides two group of sets of parameter for Randomly Reaches Current and
Detection Width, the figure is the functional diagram.
