Configuring separate axis velocity/acceleration within a vector space

Is there a way to separately configure axis velocity/acceleration when using vector space motion control? My axes motivation are very diverse and I can not simply use a vector velocity/acceleration.

I guess that your application should not use Vector configuration then. The purpose of Vector Spaces is to group axes and define vector moves, the board will calculate each axis parameters in order to achieve the vector move.
If you require different velocity and acceleration per axis you might want to try to make up your own Vector algorithm in which for the eyes of the board you are treating each axis independently, but in your software you are actually grouping them. That is, you will configure each axis by its own, and you can do multi-starts and multi-stops. The Position/Velocity/Acceleration will be calculated by your own algorithm.
Good luck!

Configuring a third axis on vector space to perform a tangential following

Is there some kind a function call/mode in flexmotion library to configure a third axis in a vector space to perform a tangential following (ie to remain tangent to the trajectory of the other two axis)?

Tulio,
Thanks for the explanation. This makes perfect sense.
The Flexmotion driver does not have any built in function to perform this type of motion, however it would be relatively straightforward to implement this for contour moves. You could set this up as a 3 axis contour move. Based on the list of X,Y coordinates, use a simple difference equation to get the slope of the trajectory at each point. Convert this slope to rotation in counts and use these values for the third axis (cutter angle). This could be implemented with just a couple VIs or lines of code with negligible processing overhead or you could even use just a spreadsheet. I have attached below a spreadsheet that shows an example of using a difference equation (centra
l difference) to get cutter positions based on X,Y trajectory data.

Need right value to Load/Read Velocity Using Input/Return Vectors

I have a servo motor with a encoder feedback of ( 4,000 counts per revolution ), maximum velocity of 6,000 rpm ( 100 rps ). I need to create 3 moving profiles with stroke time of 0.25 mm/sec, 1.0 mm/sec, and 25 mm/sec. I would like to use either Load Velocity VI or Load Velocity in RPM VI whichever is easy to set velocity, distance, and read position of my axis. More, I would like to be able to use onboard variables to set distance, velocity, and read position of the axis using input/return vectors, but I don't know how to set the right values. Do I need a conversion or multiplier number to get the right value?
Any help would be greatly appreciated.
Carlos D' Garcia.

Carols –
There is a simple vi on how to do vector moves at the following link (I also attached the file below):
http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3DF9956A4E034080020E74861&p_node=DZ52480&p_source=External
To have your axes move at different rates, you will have to replace the single ‘Load Velocity in RPM.vi’ that is wired to the Configure Vector Space.flx with three separate Load Velocity RPM.vi’s each with an axis constant (or control) wired to their axis input and the max velocity you want. This way, you will set the maximum velocity for each axis rather than all three at once.
Best of luck with your project! Let me know if you have further questions with this.

Using a class within a Vector

ok,
I writing a bank program where a user types in a string which is then broken into tokens. The tokens are separated using .nextToken( ) and the first token is used to determine what command the user wants to perform.
My problem is that I am trying to place a class that Ive created within the vector and I cant seem to be able to get the tokens into the right place or retrieve them when they are needed.
Here is what I have so far, ps I am very new to java.
Project3Functions func = new Project3Functions();
Vector vect = new Vector();
do
String firstLine = func.getLineInput();
StringTokenizer tok = new StringTokenizer(firstLine," ");
String hold = tok.nextToken();
if(hold.equals("newAccount"))
int index = Integer.parseInt(tok.nextToken());
vect.setSize(index);
vect.add(index, new Account());
vect.add(index, Account.firstname = tok.nextToken());
vect.add(index, Account.lastname = tok.nextToken());
System.out.println("a new account was created");
public class Account
static String firstname = "";
static String lastname = "";
I am trying to create a new Account in the position <index> within the vector but I dont think Im referencing firstname and lastname correctly. Also how would I get firstname and lastname out of the vertoc to print them on the screen?
Please someone help me.

Your first problem is that you are defining firstname and lastname as static in your Account class. This means that no matter how many new accounts you create, there will only be one firstname and lastname, which are shared between them. their value will be whatever you set them to most recently.
I think I know why you think you did that, however, and that leads to your second problem. You got complaints from the compiler because you tried to use Account.firstname to set firstname, etc. This only works for static variables. With your code, you are adding three new items to your vector for each new account you create, and you are adding them all to the same index. The last one wins! The other two die.
Make your Account variables non-static and change the adding code:vect.add(index, newAcct = new Account());
newAcct.firstname = tok.nextToken();
newAcct.lastname = tok.nextToken();You should also take care that you only vect.setSize(index); when vect.size() < index; otherwise, if you have items up to 10, and then add an item at 6, items 7 through 10 will be irretrievably lost.

Invoice Layout configuration for a specific customer within a sales org.

Hi,
I have a situation where the invoice layout need to be configured for one particular customer within a sales org in a different style from rest of the customers.
Could someone let me know how to do it please.
Thanks.
Best regards,
Srikrishhna

By u201Cinvoice layoutu201D, I assume you mean layout of the print output. If so, then
u2022     Set up a new output type as a copy of your standard output type. Assign an access sequence containing customer.
u2022     Add the new type to your active output determination procedure and assign an appropriate requirements routine (if any).
u2022     Assign a layout set (smartform, sapscript, adobe, etc.) that meets your customeru2019s requirements.
u2022     Maintain the condition record.
And away you go.

Cannot find a Vector within a Vector

Yo. Another noob askin about elements within a Vector.
I'm working on a OOP project in BlueJ. First time doing so, so my code is still kinda procedural (with many listeners in the same document, etc etc)
I'm creating a simulation of a 7-a-side football game. I have stored the players of each team into a vector (e.g Vector 'Chelsea' would contain 7 player objects).
I've only created three teams for simplicity, and stored these three Vectors into another Vector called 'teams'.
(the whole purpose of storing them in vectors btw, is so I don't have to pass many different player objects as arguments -
i can just send the vector, and extract them within the Listener classes)
I'm now in the new class (Start_game) and i've passed the vector to the class.
When I use the statement:
                 if (teams.contains(Arsenal))
                              +some code+
                 }I get the error message: cannot find variable 'Arsenal', when I try to compile the program.
Here's the code for the first class:

Bug of configure x-axis N9030A VXA Labview

I am using a PXA N9030A from Agilent, and measuring VXA Analog demodulation. I am running the driver（Agilent X-Series(VXA).lvlib） installed by "Find Instrument Drivers" in Labview 2013, When I set the X-scale manually, I got -221 error "Settings Conflict", however no errors if set the X Scale to "Auto". I checked the sub-VI----"Configure X-Axis.vi" recalled by Agilent X-Series(VXA).lvlib. And I found the sub-VI didn't send COUP 0 to PXA when I set X Scale Coupling "disabled". As you may know in most of the configuration of PXA, if you want to set parameters manually, you have to set the Auto to "0" meanwhile. This bug has been fixed at my side by writing "COUP 0" before writing other parameters as the attached. It works well if you want to set "Auto 1". Of coz you can combine the string together with other commands if you like. PS: First time posting here, hope this can help others who will use this sub-VI shorting debug time. Cheers

Thank u for ur advice.
I had the driver installed by Labview on my PC and I haven't realized there was a driver download page on NI untill you told me.
I found it and submitted the feedback just now.

Motion and Vector Space Question

I have an x-axis stage and a y-axis stage with 2 different leadscrew pitches, i.e.: one table has a 5 turns per inch leadscrew and the other has a 50 turn per inch leadscrew. Consequently, the stepper motors attached have to operate at different speeds (10x difference) in order for the tables to have the same velocity. I have this accounted for in the axis configuration settings in the NI MAX explorer. When I am configuring automated moves in LabView and set up a "vector space" composed of the two axis, it seems that the motors operate at the same speed and ignore the MAX settings. I thought that after intializing the controller, the current axis settings would be carried over and applied through the vector space and to the actual move
(a 2D move made in Motion Assistant). Am I missing something? Do I need to load the velocity for each axis with a flexmotion VI somewhere in the code? I'd like to command the motrs to move at 2 different speeds so the tables move at the same velocities. Any comments would be appreciated. An abbreviated sample of some of the code is attached. Thanks. ROB

Rob,
you should be able to adjust the pitch of the leadscrews by setting the stepper steps per revolution and/or the encoder steps per revolution settings in MAX accordingly (in your configuration these settings should differ by the factor of 10 for your two axes)
In your application you then have to use the Load Velocity in RPM.flx and the Load Accel/Decel in RPS/sec.flx in order to get the same resulting velocities on both axes. If you do it like this you still have to account the factor of 10 for your target position calculations.
I couldn't find out if you have proceeded like that in your application as the vi you have attached is missing a crucial subvi.
If you are using a four axes board like the PCI-7344 or the PCI-7334 there is another option:
You
could use a third axis that acts as a master for one of your axes (I would prefer the axis with the 5 inch per leadscrew). Your real axis has to be configured to follow the master axis by a factor of 1/10. In your application you configure a vector space for the master axis and the axis that is not configured as slave. Your physical signal connections need to be done to this axis and the slave axis.
Please examine the LabVIEW gearing examples for more information.
In this case you should enter the same values for stepper steps per revolution and/or the encoder steps per revolution in MAX for both axes as the pitch adjustment is done by the gearing.
The advantage of this method is that now you can set the same velocities, accelerations and even target positions for both axes and you never again have to account the pitch factor.

Capture a vector space

i want to capture a vector space (axis1&2),but when configure buffer ,the problem occur(see figure uploaded error -70006)..How should I modify in my procedure ?I am sure the board Id is configured right and the triggers are input correctly.

Vector Space Model implementation

Hi,
Does anybody know where I can find a java implementation of "vector space model"? Or simply a java program to extract keywords from an HTML page?
Actually I don't know if this is the write forum to pose this question!
Edited by: Marziye on May 28, 2008 10:55 PM

You can take a look at the Apache Lucene project. It should be possible to extract keywords from documents with it. Anyway, it is not that hard to implement the vector space model yourself!

Position, Velocity, Acceleration From Single Encoder, With TDMS Logging

I'm still a fairly new user when it comes to Labview. I started to feel comfortable enough to check out TDMS data logging and I'm kicking myself for not using it earlier.
That said, I am currently reading angular position from an encoder, and estimating it's velocity and acceleration from the sampling rate & encoder resolution. I'm using an FGV to do all the calculations and I've fine-tuned it to be as accurate as I would like.
What I would like to do is implement TDMS logging that records position, calculated velocity and acceleration with the Log and Read option of TDMS. I'd like these to be synchronized with the encoder reads, and I would like them to be handled by a single DAQmx Read vi. As far as I can see though, you can only read the position information from the encoder. I tried to drill down into the DAQmx Read.vi to create a modified version so that I could eploit the TDMS logging, but the subvi uses a call library function vi that currently is beyond my abilities.
I've been in MAX and I can't create any additional outputs for velocity and acceleration. It seems like MAX takes enough information to create approximations from the sampling clock and resolution of the encoder. Why doesn't it (or if it does, how do I implement it).

What hardware are you using for reading the encoder? I have recently completed a similar project where the encoder was connected to a counter that was triggered by the counter increasing, so that it would only read on new positions, this worked reasonably well and seems like it should work well for your case.

Issue configuring DAD on HTTP Server within 10g App Server

This time with a sensible subject...
I am trying to configure the HTTP Server within 10g Application Server with a DAD pointing to an instance hosted on the same server. However whenever I apply the DAD settings and re-start the server I am told the DAD is down. I have tried many permutations of the connection string all without success. Has anyone else encountered a similar problem and can suggest a resolution. I am carrying out the same steps as I would for a 9i HTTP Server and can only think it is a difference for 10g App Server.

Reviewing the mod_plsql services page, it says 'Module Loaded No'. I have reviewed the httpd.conf and oracle_apache_conf files and both suggest that mod_plsql should be started but this is obviously not the case.

Configuring Separate Wikis for Different Domains

Hello:
I've been trying to configure Lion Server to host several different domains on the same IP. Configuring the virtual hosts settings using the Server App seem to handle this just fine. What I'm confounded by, however, is how to have each site/domain have its own separate Wiki content. No matter which domain I browse to, I can still see all of the wiki content on the server. For my purposes, it's imperative that the Wikis from each of my sites not be visible to the others. Has anyone figured out how to do this? Perhaps there's an easy way to get this done, but it's anything but obvious to me.
Insights are most appreciated. Thanks.

kigrant:
To be able to publish each site to its own folder you'll have to split your current domain file into 3 files. I use iWebSites to manage multiple sites.. It lets me create multiple sites and multiple domain files.
If you have multiple sites in one domain file here's the workflow I used to split them into individual site files with iWebSites. Be sure to make a backup copy of your original Domain.sites files before starting the splitting process.
This lets me edit several sites and only republish the one I want.

Looking to configure a Late payment process within Collections

I am looking to implement a follow-on late payment process within the Collections Management process for past due invoices. Has anyone done this before and if so any considerations or challenges to the process? Basically as invoices fall in arrears the specialist would have the ability to create a debit memo request in reference to the late invoice for a percentage of the open amount. This would be within the Process Receivables tab. It would go through an approval process and as approved would become a debit memo for the "late payment" with reference to the debit memo request.
Any thoughts?

I would look at what you can achieve in the standard FI-AR Interest process.
I dont believe there is functionality in Collections Management for this. One of the main processes is to not update FI-AR from Collections Management.
You do have the ability to add function buttons into Collections Management (Process receivables) after Enhancement Package 5
