DRV8812: DRV8812 vibration

Raymond He

Part Number: DRV8812

dear

      The drive is a 2-phase stepping motor, which is driven by 64 subdivision. When the input PWM remains unchanged, the motor will vibrate slightly. Have any friends ever encountered this problem, how to solve it? When the motor stops, there is a small vibration, which greatly affects the effect.

 any advise？thanks in advance

    Hello, Raymond,

    "When the input PWM remains unchanged, the motor will vibrate slightly."; " When the motor stops, there is a small vibration, which greatly affects the effect."

    What is the difference between the motor stop and "the input PWM remains unchanged"? Does the motor stop when the input PWM remains unchanged?

    Regards,
