F18
Bias (for Frequency Command 1)
C50
Bias (Bias reference point for frequency command 1)
C32, C34
Analog Input Adjustment (Gain and gain reference point for terminal input [12])
C37, C39
Analog Input Adjustment (Gain and gain reference point for terminal input [C1])
If you select any analog input for frequency command 1 (set by F01), you can de-
fine the relationship between the analog input and the set frequency arbitrarily by
combining the settings for bias (F18), bias reference point (C50), gains (C32 and
C37), and gain reference points (C34 and C39).
As illustrated in the graph below, the relationship between the set frequency and
analog input level for frequency command 1 is shown by a straight line passing
through points "A" and "B." The point "A" is determined by the bias command
(F18) and its reference point (C50). The "B" is determined by the gain commands
(C32 or C37) and its reference point (C34 or C39). The combination of C32 and
C34 will apply for terminal [12] and that of C37 and C39 for terminal [C1].
The bias (F18) and gain (C32 or C37) should be set, assuming the maximum fre-
quency as 100%. The bias reference point (C50) and gain frequency point (C34 or
C39) should be set, assuming the full scale (+10 VDC or +20 mA) as 100%.
Set the peak and bottom frequencies correctly; otherwise, the inverter
may not operate. Maintain the following relationship:
(Peak frequency) > (Bottom frequency), (Starting frequency), (Stop frequency)
(Bottom frequency) < (Maximum frequency)
Analog input under the bias reference point is limited by the bias data.
