EM500 Open-Loop Vector Control Inverter User Manual 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 frequency source B); the result can be either a positive figure or a negative number. For Main and auxiliary arithmetic result is the sum (main frequency source A + auxiliary 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 number. For example, the arithmetic result of 20.00 Hz (forward) and -40.00 Hz (reverse) is -40.00Hz (reverse). 162 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
