12.7 Data Format Specification
All data in the data field of communication frame shall be represented by a 16 bit length word.
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
Data format [1] Unsigned Integer data (Positive): Min. unit 1
Example If F15 (Frequency limit, upper)= 60Hz
60 = 003C
H
Data format [2] ] Integer data (Positive, negative): Min. unit 1
Example data = -20
- 20 = FFEC
H
Data format [3] Unsigned Decimal data (Positive): Min. unit 0.1
Example: If F17 (frequency gain setting signal) = 100.0%
100.0 X
10 = 1000 = 03E8
H
Data format [4] Decimal data (Positive, negative): Min. unit 0.1
Example If: C31 (Analog input offset adjust, terminal12) = - 5.0%
- 5.0 X
10= - 50 = FFCE
H
Data format [5] Unsigned Decimal data (Positive): Min. unit 0.01
Example: If C05 (multi-step frequency 1) = 50.25Hz
50.25 X 100 = 5025 = 13A1
H
Data format [6] Decimal data (Positive, negative): Min. unit 0.01
Example: If M07 (actual torque value)= - 85.38%
- 85.38 X 100= - 8538=DEA6
H
Data format [7] Unsigned Decimal data (Positive): Min. unit 0.001
Example: If o05 (follow - up side ASR 1 constant) = 0.105s
0.105 X
1000 = 105 = 0069
H
Data format [8] Decimal data (Positive, negative): Min. unit 0.001
Example: Data = -1.234
- 1.234 X
1000 = - 1234 = FB2E
H
Data format [9] Unsigned Integer data (Positive): Min. unit 2
Example If P01 (Motor 1 number of poles) =2pole
2 = 0002
