5.3 Description of Function Codes 5.3.1 F codes (Fundamental functions)
If unipolar (terminal [12] (C35 = 1), terminal [V2] (C45 = 1), terminal [C1] (C1 function) (C40 = 0, 1), terminal
[C1] (V3 function) (C78 = 1))
For reference frequency and analog input of Frequency setting 1, it is possible to set arbitrary relationship by A point
(determined by bias (F18) and bias reference point (C50)) and point B (determined by the gain corresponding to
each analog input and the gain reference point (C32 and C34, C37 and C39, C42 and C44, and C75 and C77)).
For reference frequency and analog input of Frequency setting 2 (C30), it is possible to set arbitrary relationship by
point A (determined by bias and bias reference point (C55 and C56, C61 and C62, C67 and C68, and C82 and C83)
and point B (determined by the gain corresponding to each analog input and the gain reference point (C32 and C34,
C37 and C39, C42 and C44, and C75 and C77).
Both data of bias and gain are set with 100% as the maximum frequency. The data of bias reference point and gain
reference point are set up with full scale of analog input (10 V or 20 mA) as 100%.
<Frequency setting 1: F01>
• Analog input at or below bias reference point (C50) is restricted by bias value (F18).
• When the value set in bias reference point (C50) ≥ each gain reference point (C34, C39, C44, C77), it
is judged as incorrect setting and reference point becomes 0 Hz.
<Frequency setting 2: C30>
• Analog input at or below bias reference point (C56, C62, C68, C83) is restricted by bias value (C55,
C61 C67, and C82).
• When the value set in bias reference point (C56, C62, C68, C83) ≥ each gain reference point (C34,
C39, C44, C77), it is judged as incorrect setting and reference point becomes 0 Hz.
Example) When setting reference frequency to 0 to 60 Hz by analog input (terminal [12]) 1 to 5 V
(When maximum frequency is F03 = 60 Hz)
(Point A)
In order to set reference frequency to 0 Hz when analog input is 1 V, set bias (F18) to 0 %. At this point, 1 V has to
become the bias reference point and 1 V is equivalent to 10 % against full scale 10 V of terminal [12], therefore, set
the bias reference point (C50) to 10 %.
(Point B)
In order to set reference frequency so that the frequency becomes the highest when analog input is 5 V, set the
gain (C32) to 100 %. At this point, 5 V has to become the gain reference point and 5 V is equivalent to 50 % against
full scale 10 V of terminal [12], therefore, set the gain reference point (C34) to 50 %.
The setting method without changing reference point and by using gain and bias individually is the same
as for Fuji’s 11-series inverter.
