Hi team,
I was asking about output PWM resolution in the original thread. But I was not able to report customer's concern correctly.
What customer wants to do is to adjust <1rpm in output rotation in maximum rotation <2000 rpm. Input resolution is 13 bit so customer feels good as input (2000 / 8192 = 0.24 rpm). However, regarding output PWM, they doesn't satisfy my explanation.
I explained as below.
Fig 7-13 shows how speed command apply to output PWM.
PWM -> PWM Duty: 13bit from E.C.
PWM Duty -> DUTY CMD: Linear (= 13 bit) from Fig 7-15
DUTY CMD -> SPEED REF: Linear but threshold is 8 bit value (= 13 bit or 8 bit?) from Fig 7-16
SPEED REF -> DUTY OUT: Depends on FOC algorism, so I don't figure out about resolution from Fig7-29
Could you please advise how to answer to customer for proceed our solution to customer?
Best regards,
Hayashi
