        Indicates the start of the message.
        • UNo: Unit No. (1 byte)
        Indicates the unit number
        • SeqNo: Sequence number (Non/1/2/3 bytes)
        Sequence number is used to avoid duplicate motion when sending of
        commands improperly. An integer parameter can specify the length of
        SeqNo. (Non/1/2/3 bytes). See parameter table for more details. (Default:
        Non), 设置 2bytes
        • Parameter: Parameter (Differs depending on the command.)
        Sets the operation axis, the moving amount, etc. following a command.
        • Sum: Checksum (2 bytes)
        This information is used for the communications error check.
        Calculate the sum of the ASCII characters (‘0’ to ‘9’ and ‘A’ to ‘F’), in “Uno”,
        “COMMAND” and “Parameter” section, and take the lowest tow digit.
