How can I set the direction of motion before number of steps?

Hi all,
There's probably some really obvious answer to this that I'm just missing, but I need to separate (delay) the signal for direction change from the clock pulse train when driving a stepper motor. I'm using Labview 6.1 (oldish system) and PCI-7334 motion control card and basically need a way to set the direction for the motion before the number of steps.
Thanks.

Would it be acceptable to make a first extra step ?
Make extra step in the direction of the movement (to set the DIR output to the desired value)
Wait some time
Make movement
Another solution would be to use a digital output of the motion (or some DAQ) card instead of the DIR output. This gives you the ability to set its level and to wait before sending the pulses. However, this wouldn't allow to use the reference (home, limit switch) search functions of the motion library.
A last recommendation would be to post your question to the motion board. Then Jochen will chime in and everything will become clear...

  • How do I set the direction of the sync?

    How do I set the direction of the sync? I recall from days past that there was a window that let you choose whether to "upload" the info from your computer or "download" the info from the .MAC account. In this case I am trying to import my address book from the .MAC server. What are the new steps in 10.4? or where can this sync direction window be found?
    -todd

    Under Mac OS X 10.4 and later, the synchronization of information with .Mac is no longer the responsibility of iSync, but is instead controlled through a preference pane in the System Preferences application.
    A forum dedicated to .Mac Sync is located here:
    http://discussions.apple.com/forum.jspa?forumID=957
    Assuming that your machine is registered with .Mac and currently able to synchronize data bidirectionally, this is how you reset your data:
    • launch System Preferences
    • select the .Mac preference pane
    • press the Advanced tab
    • press the Reset Sync Data… button
    • choose one or all registered data categories from the drop down Replace: menu
    • pick a data flow direction (by default, it is set to FROM .Mac TO your computer)
    • press the Replace button

  • How can I get the direction handles to show up for the Position attribute?

    How can I get the direction handles to show up for the Position attribute?
    I have CS3 and I did the formentioned test and was able to make the handles work for the scale attribute but they don't seem to show when editing the position values.
    *I am in the graph editor looking at the "value graph"
    *I select the keys and convert the keys to auto bezier (I also tried the ease in and out buttons)
    *It changed the graph the way you might think (no longer linear) however the handles are not showing to edit further.
    *I also tried using the "convert vertex tool" (part of the pen tool) and still no luck getting those handles.
    *the handles only show up in the speed graph but that does me no good.
    Please help!
    THANKS 

    I don't have CS3 installed on any of my machines any more but your value graphs for position should look something like this:
    There are no handles for position in the Graph editor. You adjust the position curve by editing the motion path in the composition window. Press the G key to bring up the pen tool, then use the modifier keys Crtl/Cmnd and Alt/Option to temporarily switch between select and convert vertex to adjust the paths. Changes will be reflected in the value graphs. You will get editable handles with scale and rotation because these are not spatial properties. Spatial properties, position, Anchor Point, all XY & Z coordinates are edited in the comp window or in the layer window after revealing the properties. IOW, you edit anchor point position paths by opening up the layer window and choosing Anchor Point from the display options.
    The Manual isn't wrong. Here's a link to the live docs.

  • How can i set the character set ???

    hello
    now i have the following
    Message msg =
    new MimeMessage(Session.getDefaultInstance(props, null));
    how can i set the character set to be 'windows-1256'

    thanks very much

    You have to deal with the NLS_LANG environment variable,it is defined as NLS_LANG=<Language>_<Territory>.<clients characterset> .
    Where is your oracle client installed? On the the server machine, where the database resides , on another Unix system or is it a Windows client? On Windows NLS_LANG is directly related to the OS settings and stored in the registry, on Unix NLS_LANG is not set automatically and defaults (if not set) to AMERICAN_AMERICA.US7ASCII. If you are working on UNIX, this could be the reason for disordering. I'm not familiar with Chinese, so I don't know the correct setting , but a good approach would be same setting as on the server.
    Metalink note 158577.1 describes NLS_LANG very detailed.

  • How can i set the alternating colors for a table rows

    Dear All,
    Please any one help me how can i set the Alternating colors for Table Rows.
    i created a theam there i set the background alternating color to brown and i set the table design properity to alternating. but it is not reflecting.

    Hi,
    The design property in Table properties should work for your requirement. Select "alternating" value for design.
    Please see the API below:
    design
    Determines the appearance of the table. The property design can take the following values and is represented by enumeration type WDTableDesign.
    alternating - The table rows are displayed alternately in a different color.
    standard - The table background has one color. The individual table rows are displayed with grid net lines.
    transparent - The table background is transparent. The individual table rows are displayed without grid net lines.
    Check whether you have changed the right property or not? Also table should contain more than one rows to test this scenario.
    Regards,
    Jaya.

  • How can I set the page that will open, when I open a new tab, to be the same as the homepage?

    How can I set the page that will open, when I open a new tab, to be the same as the homepage?
    An app changed it to some other search engine, before installing the app, I the tab that would open was the homepage I set.
    In my case it is Google, and I want my new tabs to open on Google like they did before the installation.
    thank you,

    You can middle-click or Ctrl left-click the Home button on the Navigation toolbar to open the Home page in a new tab.

    Hi Jaime,
    Are you saying, you are getting junk characters in the email attachment? Then pls check the following. Since you want to send Japanese fonts, please pass language 'J' in both  objpack-obj_langu = '3' & doc_chng-obj_langu  = '3' instead of '3' please replace it with 'J'.
    Another thing which you may have to check is the SCOT device type. As I understand from my basis colleague, this may also affect your attachment fonts since the emails are sent through SCOT. Go to transaction SCOT-> Settings-> Device types for format conversion. Check whether wrong device type is defined for Japanese there. Hope this helps

    Gokul

  • How can I set the data binding between Web Dynpro & Database table

    Hi,
    You can write your own connection class for establishing the connection with DB.
    Ex:
    public class  ConnectionClass {
    static Connection con = null;
    public static Connection getConnection() {
    try{
    Context ctx = new InitialContext();
    DataSource ds = (DataSource) ctx.lookup("jdbc/TSPAGE");
    con = ds.getConnection();
    return con;
    }catch(Exception e){
    return null;
    You can place the above class file in src folder and you can use this class in webdynpro.
    You can have another UserInfo class for reading and writing the data into the DB .

  • In EIC, how can we set the SLA of a subcategory to none SLA-related.

    Hi Experts,
    This is our current setup in EIC...
    Category 0501 has an SLA of 8 hours. Subcategory 050101 has to be none SLA relevant. But if we put zero or blank to the SLA Target Value field, it will automatically have a due date defaulted to today. If we will not indicate 050101 on the configuration, it will have the 0501 SLA of 8 hours.
    How can we set the 050101 SLA off?
    The path: IMG --> Personnel Management --> Employee Interaction Center (EIC) --> Interaction Center Web-Client --> Application Functions --> Activity --> Service Level Agreement (SLA) --> Define SLV Properties
    Thanks in advance.

    Hi Harish and Jarret.
    @Harish, I already tried unchecking the checkbox of the Display field but the problem with this is, it will also apply for the rest of the categories. It should only be for this specific subcategory.
    @Jarret, apology, but can you explain to me further about your instruction/advise? I get the feeling that we're on to something with your advise but I didn't quite get it on how to exactly.
    1. You should build the SLA from the lowest level up...
                        -I'm not really sure how, actually.
    2. If you have 8 subcats... will put the 8 entries in the table...
                        -where do I put the 1 subcat? This is because if I don't put that "No SLA" subcat in the table, the due date of that specific subcat will automatically appear todayu2019s date.
    Thanks for both of you. I really appreciate your help. 

  • How can I set the insert date to auto update in Pages 5.2.2

    how can I set the insert date to auto update in Pages 5.2.2
    I am attempting to have the date in header auto update in a Pages file.
    I can insert it, but where is the AUTO UPDATE selection
    OS10.9.4
    thank you

    Apple never included the auto-update feature for dates in Pages v5.2.2. You would have to single-click the date, and deliberately update it.
    If you have Pages ’09 v4.3 in /Applications/iWork '09, then it will allow you to configure auto-update of the date field. Right-click on the date, set the format, and click the selection for automatically update on open.
