4-107
(1).Auxiliary frequency( Setting = 0).
. maximum output frequency (01-02, Fmax) =100%。
(2) Frequency Reference Gain (FGAIN) ( Setting =1)。
. When 04-05 is set to 1 (frequency reference gain), the multi-function analog input
AI2 can be used to adjust the frequency reference gain of AI1
. The total frequency reference gain of terminal AI1 is the internal gain (04-02) ×
FGAIN.
. The frequency reference value of AI1 is 100%.
. For FGAIN adjustment, please refer to Figure 4.3.38.
Figure 4.3.38 Frequency gain adjustment
. Example:
When the internal gain of AI1 (04-02) is set to 100% and AI2 to 5V (for example
FGAIN = 50%), the reference frequency of terminal AI1 will be 50%, as shown in
Figure 4.3.39.
Figure 4.3.39 Frequency reference gain adjustment (example)
(3) Frequency Reference bias (FBIAS) ( Setting = 2)。
. When 04-05 is set to 2 (Frequency Reference bias, FBIAS), multi-function analog
input terminal AI2 can be used to adjust the frequency reference bias of AI1.
. The total frequency reference bias of terminal AI1 is the aggregation of terminal AI1’s
bias and FBIAS’s internal bias (04-03) (for example, the total bias = 04-03 + FBIAS).
. AI1 frequency reference value =100%。
. For FBIAS adjustment, please refer to Figure 4.3.40.
