NOTE:
1. When ambient temperature is high or working current over 1.05A,  fix the module on big metal shell , or use axle flows fan dispels the heat, to make the module run reliably for a long time.
2. Half current automatically: if control machine not send out signal  in half second, driver enter half current state of automatically for electricity saving, the phase current of the winding of the electric.
