Yes, I use the TACHO pin from J8 and it is correctly synchronized with H1 signal. Besides, I have added a 0.1 uF capacitor parrallel to the '10 nF' and I got 2.88 ms at the TACHO pin. With this result, I believe the capacitor C11 on the Eval6235Q R1....
Based on the datasheet of Eval6235q (https://www.st.com/resource/en/data_brief/eval6235q.pdf) pg 4, Rpulse is given as 47k and Cpulse is given as 10n which I should get 282microseconds for tpulse. However, I couldn't get the value during my measureme...
Is changing Vref pin recommended in order to change the speed of the motor?is the changing of voltage proportional to the change of motor speed? Ex: 0.1V...50rpm / 1.0V....500rpm / 5.0V....2500rpm?Is the speed loop changes only the motor speed or mot...
Thanks, I have also written some more questions regarding the control of this board to you (private message). Hopefully you could solve/answer the questions.
Thank you for the explanation. Does this mean that the speed of motor can only be set once during setup and cannot be changed anytime? May I know if this controller can also varies the motor speed by simply changing the voltage reference (VR) input f...
