‡
0: Digital setting (non-retentive at power down)
The initial value of the frequency reference is the value of F0-08 (Preset frequency).
You can change the frequency reference by pressing and on the operation

restores to the value of F0-08.
‡
1: Digital setting (retentive at power down)
The initial value of the frequency reference is the value of F0-08 (Preset frequency).
You can change the frequency reference by pressing keys and on the

the value memorized at the moment of the last power down.
Note that F0-23 (Retentive of digital setting frequency upon stop) determines whether
the frequency reference is memorized or cleared when the AC drive stops. It is related
to stop rather than power down.

4: AI3
The frequency reference is set by analog input. The MD380 control board provides two

AI1 is 0–10 V voltage input, AI2 is 0–10 V voltage input or 0–20 mA current input,
determined by jumper J8, and AI3 is 0–10 V voltage input.

voltage of AI1, AI2 and AI3 and the frequency reference, three of which are linear
(point-point) correspondence and two of which are four-point correspondence curves.
You can set the curves by using function codes F4-13 to F4-27 and function codes in
group A6, and select curves for AI1, AI2 and AI3 in F4-33.

range).
You can set the mapping relationship between DI5 pulse reference and the
corresponding setting in F4-28 to F4-31, and the relationship is a linear curve. 100%
of the corresponding setting of pulse reference corresponds to the value of F0-10
(Maximum frequency).
