hi guys,
I am creating the stepper motor driver with A4989 stepper driver ic. every thing is OK but the motor is generating too acoustic noise. the circuit is used for converter is attached.
other configurations for a4989 is:
PFD2 = 1, PFD1 = 0
MS2 = 0, MS1 = 0
SR=1
In your opinion, what's the bug?
Is that configuration for converter is problem?
Any help is appreciated !!
