? Encoder inputs data, which may include lists, numbers, text, personal medical records or forms. This data may be either new or existing and is generally edited thoroughly. Equipment may include electronic files, scanners and sophisticated electronics based on character recognition. Let's us see encoder of the memory function.

? Encoder to turn the output pulse by counting the device to know its location, When the encoder is not fixed, or power failure, rely on counting the device's internal memory to remember the location. Thus, when the power outage, the encoder can not have any movement, when the call work, The encoder output pulse process can not interfere with the loss of pulse, or, counting equipment will offset the zero memory.
