6. Description of Parameters
6.10.4 Write Frequency/Torque Reference
You can set frequency reference, torque limit, V/F separation voltage, PID reference and PID
feedback via communication address 1000H. The data range is -10000 to 10000, corresponding
to -100.00% to 100.00%.
For example, to set main frequency reference to 8000 by using Modbus protocol, first set F0-03
= 9 and send write command 01 06 10 00 1F 40 84 CA. In the command,

To set torque reference to -8000, send write command 01 06 10 00 E0 C0 C4 9A. In the
command, E0C0 is the lowest four bits of the hexadecimal number converted from -8000.

01H (settable): AC drive address
06H: write command
1000H: Communication address of giving the toque reference
1F40H: torque reference (converted into decimal 10000)
84CAH: CRC check
Range of frequency reference given via communication is -10000 to 10000,
Note
corresponding to -100.00% to 100.00%. -100.00% corresponds to negative
maximum frequency, 0.00% corresponds to minimum frequency, and 100.00%
corresponds the maximum frequency.
Suppose that F0-10 = 50 Hz, if frequency reference in write command is 1F40H,
converted to decimal 8000, frequency reference that is written is 50 x 80.00%
= 40 Hz.
