Part Number: DRV8436

Customer testing DRV8436EVM with GUI, when customer setting Target speed at 5000, the motor will run a while ,then the motor will stop running. Would you please kindly help to check where is wrong with the setting. thanks !

  • Elan,

    Please measure nSLEEP pin, Enable pin and STEP pin signal on a scope.

     5000 pps with full step setting may be too fast for that motor.

    Best Regards,
