Ardiuno UNO, a4983 driver and stepper motor

hi
my motor doesn't move, think problem code

code: [select]

// stepper
    #include <stepper.h>

    // steps value 360 / degree angle of motor
    #define steps 200

    // create object on pins 6 , 7
    stepper stepper(steps, 6,7);

    void setup()
    {
    }
    void loop()
    {
    ///// turn stepper 200 steps 1 sec delay between steps @ 60rpm
    /// reverse direction , 50 steps @ 20rpm 1sec delay between steps
    stepper.setspeed(1);
    stepper.step(200);
    //delay(1000);
    //stepper.setspeed(20);
    //stepper.step(-50);
    //delay(1000);
    }

i using 12v battery, motor:
