Setting 1: 3 Channels Added Together
To set a combined input, set b1-01 to 3 (Option PCB) or F2-01 to 1 (3 Channels Added
Together).
The resulting value of adding the input from terminals V1 to V3 becomes the frequency
reference.
The following block diagram illustrates combined input. Use parameters F2-02 and F2-03 to
adjust the analog reference gain and bias for combined input.
