Like this,the FPGA generate pwm to the stepper controler,and the stepper controler will make the stepper motor rotate, the frequency of pwm more faster,the stepper motor rotate more faster.I want to the stepper motor run in variable speed,So,I need the variable frequency pwm. But why the stepper frequency should fixed 1Hz? https://alteraforum.com/forum/attachment.php?attachmentid=14953&stc=1 The increase of the pwm frequency means the stepper motor's rotation speed increase.someone call this acceleration. The acceleration should be stable.And,if the stepper frequency more smaller,the noise will be lower when stepper motor increasing its speed. Do I express clear about why I want to achieve?
