FC address
0F
Function
00 00
Register address 0 is f requency converter control word.
00 20
The bit number is 32.
04
The byte number is 4
7C 04
Control word. “7C 04”swap high byte and low byte, the value
is 0x047C
Note:
0x047C convertes to binary is: 0000 0100 0111 1100 are
corresponding to the coil address 0-15
9A 19
Frequency reference.“9A 19” swap high byte and low byte, the
value is 0x199A. Frequency is 40% of C03.03(see the following
f requency conversion speci

Frequency conversion speci
fi
cation:
If you want to set the f requency as 20Hz, 20Hz is 40% of the maximum
f requency (it determined by the C03.03 parameters, the default is 50Hz).
Calculation method: 20/50 * 16384 = 6553.6 converted to hexadecimal 0x199A.
So if you want to set the f requency as feq, you can calculate: feq / C03.03
× 16384 then converts into hexadecimal. 16384 converts into hexadecimal is
0x4000. The reason to be multiplied 16384 is for a higher accuracy.
