Source B
1: Main Frequency Source
A - Auxiliary Frequency
Source B
2: The Bigger of Main A
and Auxiliary B
3: The Smaller of Main A
and Auxiliary B
As for main and auxiliary arithmetic, final results are limited by both the lower limit
frequency (F00.19) and the upper limit frequency (F00.18).
F00.08=0: Main Frequency Source A + Auxiliary Frequency Source B
Main and auxiliary arithmetic result is the sum (main frequency source A + auxiliary
frequency source B); the result can be either a positive figure or a negative number. For
example, the arithmetic result of 20.00 Hz (forward) and 40.00 Hz (reverse) is 20.00 Hz
(reverse).
F00.08=1: Main Frequency Source A - Auxiliary Frequency Source B
The arithmetic result is the difference between main frequency source A and
auxiliary frequency source B, which can be positive or negative; take forward 20.00Hz
and reverse 40.00Hz for example, the arithmetic result is 50.00Hz given upper limit
frequency F00.18=50.00.
F00.08=2: Maximum of Main Frequency Source A and Auxiliary Frequency
Source B
A main and auxiliary arithmetic result is the bigger of main frequency source A and
auxiliary frequency source B; the result can be either a positive figure or a negative
number. For example, the arithmetic result of 20.00 Hz (forward) and -40.00 Hz (reverse)
is 20.00 Hz (forward).
F00.08=3: Minimum of Main Frequency Source A and Auxiliary Frequency
Source B
Main and auxiliary arithmetic result is the smaller of main frequency source A and
auxiliary frequency source B; the result can be either a positive figure or a negative
