Data Format Specification
All data within the data field of the communication frame consist of 16 bits binary data.
(MSB) (LSB)
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
16-bits binary data
(Negative data is treated with two’s complement)
Data Format [1]: Integer Data (Positive): Min. Unit 1
Example) If F15 (Frequency limiter, high limit) = 60 Hz,
60 * 1 = 60 = 003C
H
Data Format [2]: Integer Data (Positive, Negative): Min. Unit 1
Example) If F18 (Bias frequency) = -20 Hz,
-20 * 1 = -20 = FFEC
H
(two’s complement)
Data Format [3]: Decimal Data (Positive): Min. Unit 0.1
Example) If F17 Gain (for frequency setting signal) = 100.0%,
100.0 * 10 = 1000 = 03E8
H
Data Format [4]: Decimal Data (Positive, Negative): Min. Unit 0.1
Example) If H28 (Droop operation) = -5.0Hz,
-5.0 * 10 = -50 = FFCE
H
(two’s complement)
Data Format [5]: Decimal Data (Positive): Min. Unit 0.01
Example) If C05 (Multi-step frequency 1) = 50.25 Hz,
50.25 * 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 * 100 = -8538 = DEA6
H
(two’s complement)
Data Format [7]: Decimal Data (Positive): Min. Unit 0.001
Example) If o05 (Constant I of feedback speed controller) = 0.105s,
0.105 * 1000 = 105 = 0069
H
