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 frequency conversion specification).
37 B3 CRC check
Frequency conversion specification:
If you want to set the frequency 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 frequency 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.

Field Description
01 FC address
10 Function
0B D5 The register address of C03.03 is 303*10-1=3029(0x0BD5)
00 02 Register number
04 The byte number of data is 4
00 00 EA 60
0x0000EA60 convert to decimal number is 60000. So the
value of C03.03 is 60000*0.001=60.000
