Current display mode for input X1 SCL shown in black: Scaling factor is active. COMP shown in black: Error compensation or axis-error compensation is active for the currently displayed axis Elapsed time of running stopwatch: If the stopwatch is stopped, the box appears dimmed. mm, inch, DEG, DMS or rad: Currently active unit of measure Currently active datum: The ND 280 allows you to work with two different datums. Indicates the soft-key page (soft-key row) you are currently on. 2 3 4 Position display: Current position value (length or angle) Message line for displaying information, errors or warnings. Status display: SET: If you enter a new value during datum setting, the SET symbol will start flashing. REF: The REF symbol is flashing until the reference mark evaluation for the displayed axis has been completed (if an incremental encoder is connected). 5 and 6 1, 2, 3, 4. . .

ND 280 41 II ­ 1 Installation and Electrical Connection II ­ 2 Installation Setup II ­ 2 Installation Setup INSTALLATION SETUP menu The ND 280 offers two categories for setting up operating parameters: JOB SETUP and INSTALLATION SETUP. The JOB SETUP parameters are used to accommodate specific machining requirements for each job, see "Job Setup" on page 27. The INSTALLATION SETUP menu is used to establish encoder, display and communication parameters. To call the INSTALLATION SETUP menu: Begin by pressing the SETUP soft key. Use the numeric keys to enter the correct passcode (95148) and then press ENTER. Fig. II. 7 INSTALLATION SETUP menu INSTALLATION SETUP parameters are established during the initial installation and, most likely, will not often change. For this reason, the INSTALLATION SETUP parameters are protected by a passcode. Once you enter the passcode, it will not have to be entered again until you cycle power. 42 II Installation, Specifications When in the INSTALLATION SETUP menu, the following soft keys will be available (see Fig. II. 7): JOB SETUP Press to begin accessing the JOB SETUP parameters (see "Job Setup" on page 27). IMPORT/EXPORT Press this soft key to call the IMPORT or EXPORT soft keys for transmitting the operating parameters (see "Serial data transfer with the Import or Export function" on page 64). HELP This soft key will open on-line help. Press the NAVIGATION key to move through the pages of menu parameters. To view and change menu parameters, use the UP/ DOWN arrow key to highlight the parameter of interest and press the ENTER key. On the following pages you will find more information on the menu parameters. ND 280 43 II ­ 2 Installation Setup II ­ 2 Installation Setup Setting up the encoder In the ENCODER SETUP form you configure the ND 280 for the connected encoder: The cursor will default to the ENCODER SETUP field upon opening Installation Setup. Press the ENTER key to confirm your selection. The cursor will be in the ENCODER TYPE field. Select the encoder type by pressing the TYPE soft key: LINEAR: Linear encoder ROTARY: Rotary encoder Press the ENTER key to confirm your selection. The ND automatically enters the measurement signal received in the ENCODER SIGNAL field: NO SIGNAL, 1 Vpp, 11 µApp ENDAT 2. 1 or ENDAT 2. 2.
