When the output frequency of frequency converter, in the range of positive and nagetive detection
amplitude of the detection value at any time, muti-function DO output ON signal.
VD520 provides two sets of any frequency reaching detection parameters, set the frequency value
and frequency detection range respectively. The diagram below is a diagram of the function.

When the output current of the inverter is less than or equal to zero current detection level, and the
duration is more than the zero current detection delay time, the inverter muti-function DO output ON
signal. Below is the zero current detection schematic diagram.
