Range
PC-18
Frequency detection value (FDT1
voltage level)
0.00Hz~max output frequency
PC-19
Frequency detection hysteresis value
(FDT1 voltage level)
0.0%~100.0% (FDT1 level)
When the operating frequency is higher than the frequency detection value, the inverter multi-function output Y
outputs ON signal, and when the frequency is lower than the detection value, the Y terminal output ON signal is
cancelled.
The above parameters are used to set the detection value of output frequency and the hysteresis value of output
action release. Where PC-19 is the percentage of the hysteresis frequency relative to the frequency detection
value PC-18.

The frequency detection function is the same as that of FDT1. Please refer to the relevant description of
function code PC-18 and PC-19.

When the output frequency of the frequency converter is within the positive and negative detection range of
frequency detection value, the multi-function Y outputs the ON signal.
VH6 provides two groups of frequency reached detection parameters, setting frequency value and frequency
detection range respectively. The figure below is the schematic diagram of this function.
