The running frequency of the inverter, in a certain range of target frequency, inverter multi-function
DO output ON signal.
This parameter is used to set the detection range of frequency reached, which is relative to the
percentage of the maximum frequency. The diagram below is the frequency reached.

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.
VD500 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.
