To send reference via communication like 0 to 100%, it is possible to use the high-resolution mode. We can change the precision of LFR (send by communication) to have high resolution.
To activate the high-resolution mode, the bit 9 of CMI must be set to 1.
bit 9 = 1: High resolution (references, output speed and ouput frequency in 32767 points for 600 Hz)
600/32767 =0.0183
600 Hz= 32767
1 Hz= 32767/600= 54.611
50 HZ =50x54.611=2730.55
LFR=>100=> the drive will run at 1.8 Hz
LFR=>1000 => the drive will run at 18.3 Hz
LFR=>2000=> the drive will run at 36.6 Hz
LFR=>2500=> the drive will run at 45.8 Hz
LFR=>2600=> the drive will run at 47.6 Hz
