TECO A510s - Frequency Reference Gain Adjustment (Example); Bias Adjustment; Frequency Reference Bias (FBIAS)

4-175
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 4.4.39.

04-05=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 sum of internal bias set by parameter 04-03 and FBIAS.
The maximum frequency reference for AI1 is 100%.
