Downloading Parameters from PC to Controller

AT THE COMPUTER AT THE HEIDENHAIN CONSOLE
  1. Set the black boxes for whichever computer you are using and for the Heidenhain CNC mill.
     
  2. Load the floppy disk containing the parameters into the drive.
     
  3. Set the communication parameters for 2400, E, 7, 2, COM2.
    Run the "HEID-24" batch file to do this automatically.
     
  
 
  1. Replace the 3 "AA" cells if weak or old.
     
  2. Turn on controller at the wall disconnect.
     
  3. Upon warming up, console's CRT will display a message in German (meaning "memory test"):
          SPEICHER-TEST
     
  4. Next, upon completion of the memory rest the CRT will display the message:
          BETRIEBSPARAMETER GELOSCHT

    X+ 0,000Y+ 0,000
    Z+ 0,000A+ 0,000

     
  5. Press the MANUAL key (the one with the hand icon). The CRT will display the message:
          PLC:-PROGRAMM-SPEICHER GELOSCHT
     
  6. Press the UP ARROW key once. The CRT will display the message:
          MASCHINENPAR.-PROGRAMMIERUNG
          MASCHINEN-PARAMETER        MP 0 ?
     
  7. Press the EXT key. The CRT will display the message:
          EXTERNE DATEN EINGABE
     
  1. At the computer (again), type in COPY and the path & filename and applicable serial port and press the ENTER key.
          a)   For example: COPY B:PARAMTRS.TXT COM2:
     
                1) The parameters will now be downloaded
                    from the computer.
     
          b)   After the parameters have been completely uploaded into the controller; the computer's CRT will display 1 file(s) copied.

  1. Press the CE (Clear Entry) key. The CRT will display, NC PROGRAM MEMORY ERASED
     
  2. Press the NO ENTER key, press the yellow axes motor power button and proceed to execute the "pass-over" process to "home-out" the three axes. Upon completion, the three axes positions will be displayed in metric units.
     
  3. Press the MOD button twice until the CRT displays the message, CHANGE MM/INCH.
     
  4. PRESS THE ENTER button. The three axes positions will be displayed in inch units.

TO CHECK/VERIFY/CHANGE PARAMETERS AT THE HEIDENHAIN CONSOLE

  1. Press the MOD key once.
     
  2. Press the UP ARROW once until the CODE # prompt appears.
     
  3. Key in the code number 95148 and press the ENTER key. Press the GOTO key, the appropriate numbers, and press the ENTER key to access the desired parameter or use arrow keys to cursor thru parameters. Edit if needed.
     
  4. Exit by setting cursor at parameter # zero and press the DEL BLOCK key (with the square icon) to exit.
     
  5. If necessary, set the axis limits (X & Y) for +30000 & -30000 (mm values).
