5.7 Frequency Source Selection

F0.03
0: Digital setting (No saving at power failure)
The initial value of the set frequency is the value of F0.08 (Preset frequency). You can change the set
frequency by pressing Λ、V on the operation panel (or using the UP/DOWN function of input
terminals).When the inverter is powered on again after power failure, the set frequency reverts to the value of
F0.08.
1: Digital setting (save at power failure)
Basic operations are same as "0: Digital setting".
The only difference is that when the inverter is powered on again after power failure, the set frequency
is the value memorized at the moment that power goes out.
Note: The hidden parameters set down by F0.20 cleared or unclear 0, factory default is cleared down.
2: AI1 (0–10 V voltage input)
3: AI2 (0–10 V voltage input or 4–20 mA current input, determined by jumper )
4: AI3 (0–10 V voltage input)
The frequency is set by analog input.
5: Pulse setting (X5)
The frequency is set by X5 (high-speed pulse). The signal specification of pulse setting is 9–30 V
(voltage range) and 0–100 kHz (frequency range). The corresponding value 100% of pulse setting
corresponds to the value of F0.10 (Maximum frequency).
6: Multi-command
In multi-command mode, combinations of different terminal X statuses correspond to different set
frequencies. The JT550 supports a maximum of 16 speeds implemented by 16 state combinations of four X
terminals (allocated with functions 12 to 15)in Group FC. The multiple references indicate percentages of the
value of F0.10(Maximum frequency).
If a terminal X is used for the multi-command function, you will have to adjust settings in group F2,
referring to the function explanations for group F2.
