Print & Read Me : Hemmer Servo Design Programs                                    2-17-09

 

Printing & reading this file is essential.

 

Note: This file is also contained in the Auxialiers. folder.

          It is easier to print it from the Auxialiaries folder.

 

Note: The unzipping, installation, and operating tryout require about half an hour. The curve plotting software installation and tryout also require about half an hour.

                 

For electronic transfer: This works fine if you have wide band internet service where download speed is about 5 Mbps or greater.

    If the downloaded Hemmer.zip folder has not been unzipped yet, double click the Hemmer.zip folder icon and follow the WinZIP directions for unzipping or de-compressing it. Note the path and folder where it is stored.

 

   Repeat the above procedure for the Auxiliaries.zip folder and the Plotting.zip folder. *

 

For compact disk transfer: This is recommended if your download speed is low as in dial-up service. A free CD with all the necessary information will be mailed to you at your request from the Hemmer Engineering Corp.  Insert the Cd in your CD-ROM drive and copy the contents to a folder of your choice, then remove the CD. *

 

* After the final installation procedure is completed for the HemmerDeploy program (after trying the free executions in the HemmerDeployDemo version) you may delete this folder.

 

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

 

   This can be done at any time: Open your word processor then browse for and open the Hemmer Manual.doc file in the Auxiliaries folder. This is a Microsoft WORD file. Several worked out examples are provided in the manual; This makes learning how to use the programs easy. These examples represent the majority of practical feedback control problems. 

 

   View the manual to get an idea of what you can gain from the software. You can go immediately to any desired chapter by clicking the chapter in the Table of Contents.  You can study the chapters most pertainent to your work and ignore chapters of little interest. You can zoom in or magnify 150 % withot exceeding the page size.  

 

  The Hemmer Manual will be placed in the installation folder. It is provided as a substitute for Help files. A black & white hard copy and a CD containing the manual will be mailed to software purchasers.

   I  Installation Procedure

 

1. Open the “HemmerDeployDemo” folder, which was in the Hemmer.Zip folder.       

    ( Do not open the “HemmerDeploy” folder at this time.)   

    Double click “Setup Launcher” or “Setup.exe” and follow the instructions to install the software. Use all default locations.

 

    The default path & folder for the installed software, called the Installation Folder, is:  "C:\Program Files\Hemmer Servo Design".   This is created during the above  installation.

 

    When the installation is finished, copy the executable file,“HemmerServoDemo”, to "C:\Program Files\Hemmer Servo Design".    

 

2. Open the HemmerDeployAuxiliaries folder, select all files & folders,  then move them into "C:\Program Files\Hemmer Servo Design".

                

3. Open "C:\Program Files\Hemmer Servo Design" , right click the screen, select “Arrange icons by”, click “type”, then click “Show in groups”. This is an optional step done to facilitate the finding of files & folders.

 

   Go to the executable, “HemmerServoDemo”,  which is shown in the  Applications Group, and create a shortcut on the Desktop.

 

 II  Operating Procedure 

 

1. Make sure the screen resolution is set at approximately 1024 by 768 pixels. If it is set at 800 by 600 pixels, the scroll bars and "Run" button will not be visible in the spreadsheet of Paragraph 4 below. To change the setting, click Control Panel, Display, and Settings. Then move the pointer for screen resolution to approximately 1024 by 768 pixels, then click OK.

 

2. Double click the "HemmerServoDemo" shortcut on the desktop to produce an ExeShield Trial screen.

   

3. Click “try” to produce the Hemmer Servo screen, then click "Programs" in the upper left corner.

4. Click the first program to be demonstrated: Hydrostatic Transmission  

   A spreadsheeet will appear with three lists, Options, Input Parameters, and  Results. Click a tab near the top of the form to display a desired list.

( Options are available for all programs, except the Drive Train and Servo Errors programs. )

 

5. Click File in the upper left corner, then click Open. Browse to find and select  "C:\Program Files\Hemmer Servo Design\Input Files\Examples\V-HT-13", then click “Open”. Click the Input Parameter tab to display the input values for this example. (You could change values before running, but leave this to a later session.)  

 

6.  In the upper right corner, click “Run”. Click “No” for the option to change values. A set of  tables and notes will soon appear in the Results tab. These  contain values for the inputs and the calculated outputs.

 

7. If you want to print the screen display, click File then click Print in the upper left corner.

 

8. Click the X in the upper right corner of the  smaller form to close the file. You may then make more runs for this execution.

 

9. Repeat steps 3 through 8, except:

   Click Amplifier in step 4 and select AMP in step 5. (Skip step 7 for AMP.)

 

   The next 4 runs are for Example 10 with position control:

 

   Click Drive Train           in step 4 and select V-DT-10   in step 5.

   Click Servo Errors          in step 4 and select V-SE-P-10 in step 5.

   Click Frequency Response    in step 4 and select V-FR-P-10 in step 5. 

   Click Transient Response    in step 4 and select V-TR-P-10 in step 5. 

  

10. Click the X in the upper right corner of the largest form to close the session. You have now used up the first of 10 free executions in the demo.

 

 III Curve Plotting

 

Note: File extenders, such as .exe or .dp are not shown in some computers.

 

   Open the Plotting folder to install 4 programs used for plotting curves. Perform the installations in the order listed below. Use all default locations and default options. You may exit each application immediately after each installation. This requires less than half an hour and occupies 95 MB on your hard drive.

 

(a)  Install Ghostscript by double clicking gs704w32.exe.  

 

(b)  Install Ghostview by double clicking gsv42w32.exe.

     A shortcut will automatically be created for Ghostview.

 

(c)  Install Tcl/Tk by double clicking tcl830.exe. (required for the GUI)

 

(d)  Install Dataplot by double clicking Setup_Dataplot.exe

     Shortcuts will automatically be created for Dataplot_GUI and Dataplot.

 

(e) Open the "C:\Program Files\Hemmer Servo Design" then move the contents of the DP Macros folder into "C:\Program Files\NIST\Dataplot\MACROS” and then create a shortcut on the desktop for the MACROS folder.

 

(f)  Go to the desktop.

 

To produce frequency response curves for Example 10 from the Hemmer Manual:

1. Double click the Dataplot_GUI icon on the desktop.

 

2. In the command line at the bottom of the form, type “Call FR10p.DP”. 

 

3. Press “OK”. The plot will appear in the upper right corner of the screen.

 

4.  Exit Dataplot, then double click the shortcut to GSView32.exe, click OK in the GSVview registration box, click “File”, click “Open”, then select C: \ Program Files \ NIST \ Dataplot. At “Files of Type”, select “All Files” then select “DPPL1F.DAT” then click “Open”. (For future runs, you can simply select DPPL1F.DAT from a list of files after clicking “File”.) 

 

   A high quality plot, including colors, will appear on the screen. The quality of the graphs are excellent, both as screen displays and as  prints. The ability to use different colors for several curves makes it much easier to distinguish one curve from another. To obtain a full screen image, click view then click full screen. To exit, press the Escape key then click the X in the upper right corner. 

 

  To produce transient response curves for Example 10, repeat steps 1 through 4 above, except type “Call TR10p.DP” in step 2. See Chapter 7 in the Hemmer Manual for general plotting instructions and other examples.

 

 Final Instructions

 

    The demo version provides a free trial period of 10 executions to try out the programs. An execution will last until you click the outwermost X in the upper right hand corner of the form, therefore you can make several runs of each program per execution. On rare occasions it may be necessary to end an execution when using the Frequency Response Program and them return to make additional runs. The software will be fully functional, except you will not be able to save your input files. It is recommended that you run the example files described in the Hemmer Manual and stored in the Examples folder. 

 

     When you have decided to  purchase the software,  remove or uninstall the above demonstration version and its shortcut from your computer and delete the HemmerServoDemo file in the C:\Program Files\Hemmer Servo Design folder, then repeat Step 1 of the Installation Procedure, except open the HemmerDeploy folder instead of the HemmerDeployDemo folder.

 

    Create a shortcut for “HemmerServo” on the desktop. There may be 1 or 2 free executions in the final version to demonstrate the SAVE function

 

    Double click the shortcut to the executable, "HemmerServo". The ExeShield screen will displayed. Copy the protection version and registration numbers from the screen and send them with a payment check or money order to the Hemmer Engineering Corporation. When payment is received, an unlock key code will be sent to you.

 

 

    When you receive this key code, double click the "HemmerServo" shortcut. The ExeShield screen will displayed. Click the "register" button. When a new screen appears, Click the “register” button. Write your user name, exactly as it was submitted to Hemmer Engineering, and the key code in the assigned spaces, then click OK. Your software will then be registered and you will be able to run the programs anytime you click the executable, "HemmerServo" or its shortcut. The ExeShield Trial screen will no longer appear before each run; The protection will be invisible.  

 

    You will now be able to save your input files, unlike the demonstration version. This is done after Step II-5 as follows:

 

   In the upper left corner of the form click File then click Save. If you have created a new file, specify a name then browse to select "C:\Program Files\Hemmer Servo Design\Input Files” for its location, then click Save. If you have changed some values in an old file, browse to find its name in the above folder, select it, then click Save.

 

   Note: When repeating a Frequency Response Program execution, it is sometimes necessary to exit HemmerServo and then return to HemmerServo, modify the Input file as desired, then give the Save command, in order to properly Save the revised Input file.
