Example:
Using a 16-bit Analog Input as speed reference (profile velocity mode).
resolution = 4096 inc/rev
max. speed = 3000 rpm
analog input (-32768 .. +32767)
max_speed = 3000 / 60 x 4096 = 204800 inc/s
max_speed = 32767 x gain / 256
so, gain = 1600
Parameter setting:
0x3823,1 = 0x60FF0000
0x3823,2 = 0
0x3823,3 = 1600
