Hi,
Implementing level 8 of Insta SPIN BLDC motor under load with DRV8301 kit and 48V supply. Under the load motor could reach 42 RPM (speedref - 0.075). Further increase in speedref stops the motor with speed dropping to zero. Tried various PID parameter changes (incl FT) but not successful. The attached picture illustrates PID outputs very well within <0.001 and speed very much controlled at speedref of 0.075
At level 7 the motor could reach 420 rpm with speed ref of 0.7. Hence the input bus voltage of 48V may not be the reason.
Pl suggest how to sort this and increase the motor speed under load.
thx & rgds
