Mantissa part
Exponent part: 0 to 3, Mantissa part: 1 to 9,999
Value represented in this format = Mantissa part × 10 to the power of (exponent part - 2)
Value Mantissa part Exponent part 10 to the power of (exponent part - 2)
0.00 to 99.99 0 to 9,999 0 0.01
100.0 to 999.9 1,000 to 9,999 1 0.1

Example: Power Consumption Monitor (3010-16 hex) = 10.02 kW
10.02 = Mantissa part: 1,002 (3EA hex), Exponent part: 0 = 03EA hex →
Example: Power Consumption Monitor (3010-16 hex) = 100.2 kW
100.2 = Mantissa part: 1,002 (3EA hex), Exponent part: 1 = 43EA hex →
Example: Power Consumption Monitor (3010-16 hex) = 9,999 kW
100.2 = Mantissa part: 9,999 (270F hex), Exponent part: 2 = 670F hex →
Data Format [29]: Positive/Negative Data with ±20,000 as ±100%
Example: Frequency Reference (3002-02 hex) = -20,000 (= -100% = Maximum output frequency)
-20,000 = B1E0 hex →
Example: Frequency Reference (3002-02 hex) = 20,000 (= 100% = Maximum output frequency)
20,000 = 4E20 hex →
Data Format [35]: ROM Version
Setting range: 0 to 59,999
Example: ROM Version
(3003-1A hex) = 0064 hex
→ 0064 hex = 100
Data Format [37]: Floating Point Data (Load Shaft Speed, etc.)
