Input pulse 0-10K can correspond to output frequency -50Hz~50Hz (5K corresponds to 0Hz) by setting the
function of corresponding setting for max/min input pulse frequency. The function code F446 sets the input pulse
range corresponding to 0Hz. For example, when F446=0.5, the pulse range from (5K-0.5K=4.5K) to
(5K+0.5K=5.5K) corresponds to 0Hz. So if F446=N, then 5±N should correspond to 0Hz. If the pulse is in this
range, inverter will output 0Hz.
0HZ voltage dead zone will be valid when corresponding setting for min pulse frequency is less than 1.00.
The unit of corresponding setting for max/min input
pulse frequency is in percentage (%). If the value is
greater than 1.00, it is positive; if the value is less
than 1.00, it is negative. (e.g. F441=0.5 represents
–50%).The corresponding setting benchmark: in the
mode of combined speed control, pulse input is the
accessorial frequency and the setting benchmark for
range of accessorial frequency which relatives to
main frequency (F205=1) is “main frequency X”;
corresponding setting benchmark for other cases is
the “max frequency”, as illustrated in the right
figure:
