Polarity: 0 → Positive (+), 1 → Negative (-), Exponent part: 0 to 3, Mantissa part: 1 to 999
Value represented in this format = (Polarity) mantissa part × 10 to the power of (exponent part - 2)
Value Mantissa part Exponent part 10 to the power of (exponent part - 2)
0.01 to 9.99 1 to 999 0 0.01
10.0 to 99.9 100 to 999 1 0.1
100 to 999 100 to 999 2 1
1,000 to 9,990 100 to 999 3 10
Example: 1st Acceleration Time 1 (F07) = 20.0 s
20.0 = 200 × 0.1 → 0000 0100 1
