REQUENCIES
This menu is used to adjust the various speeds used by the DG-Mini during operation of the door.
Since the speed of the motor is directly proportional to the frequency of the voltage applied to it, the DG-Mini is able
to control the door’s speed by controlling both the voltage and frequency during door movement.
