When the operating frequency of the frequency inverter is within a certain range of the target frequency, the
multi-function (04) DO of the frequency inverter outputs an on signal.
This parameter is used to set the detection range of frequency arrival and this parameter is a percentage of the
maximum frequency. Figure 5 - 10 is a schematic diagram of frequency arrival.

When the output frequency of the frequency inverter is within the positive and negative detection range of any
frequency detection value, the multi-function DO (No. 26 and No. 27) outputs on signal
HV610 provides two groups of random arrival frequency detection parameters, setting frequency values and
frequency detection ranges respectively. Figure 5 - 11 is a schematic diagram of this function.
