Read analog while doing an open loop stepper move

I am useing the stepper to drive a slide to measure the displacement with a laser and force with a strain tranducer. I need to know the force displacement curve of valves we manufacture. The motoin software generates an error saying you cann't read analog while moving the stepper.

I have tested this with the same hardware and it's working properly on
my system. I can move my stepper motor while reading analog data from
the analog inputs. I'm using NI-Motion 7.0. Please update your driver if you are using an older version.
If the error doesn't disappear please tell me the exact error number and message that you get.
Thanks,

Open item not found while doing process open items - F-32

The customer account shows 2 open items ( 1 Invoice and 1 Payment documents) during account clearing with f-32 t.code, only payment document is appearing. whether reason code maintained in invoice document any way afftects in account clearing process.

check the posting date of the invoice and payment.
You can enter more, go to edit, select more.
Has one of the entries got a special GL entry.
Lastly if all else fails, on the selection screen enter both document numbers.
If only one appears, make sure it has not been cleared already.

.PDFs do not open and Reader XI itself does not open either

I can see an instance of AcroRD32.exe in the Process list in Windows Task Manager and the Mem Usage keeps increasing, but nothing ever displays. Running XP.
Reading through other posts, the common remedy was to repair in Control Panel. Tried that. Also completely uninstalled Reader, then ran another Adobe clean-up program in case fragments remained, then reinstalled. Still nothing.
I'm pretty sure that this problem began when I installed Reader XI.
Grateful for any constructive suggestions.
Thanks.

Found a post by Pat Willener (sp) replying to someone else with a similar issue. The following suggestions were made:
"Regarding your problem, three things to try...
Using Windows Explorer navigate to C:\Program Files (x86)\Adobe\Reader 11.0\Reader, then double-click on Eula.exe and accept the license agreement
Can you open Adobe Reader by itself? If so, try disabling Protected Mode [Edit | Preferences | Security (Enhanced)].
It could even be a malware issue; see http://helpx.adobe.com/acrobat/kb/reader-core-dll-error.html
I followed #1 and accepted the EULA. No change.
I cannot open Reader by itself.
Already followed the steps in #3.
Still trying to patiently wait for someone with some more insight. Thanks.

While doing MIGO transfer within plant batch no should not be changed.

Dear All,
While doing MIGO transfer within plant (movement type 311), any user is able to change the batch and can assign new batch no.The process is as under.
T.Code-- MIGO
M.type --311
Go in Transfer posting tab.
In "From selection",
Select Material and that material will be displayed in Destination selection automatically and can't be change.
Select Plant and that plant will be displayed in Destination selection automatically and can't be change
Select Storage location(from where material to be transfered) and we have to select storage location in "destination selection" where material is to be transfered.
Same way Select Batch No in from selection and indestination selection batch is not coming automatically and we can give any batch no.So we do not want to allow this change and the batch no must remain same as selected in "from selection".
Now how can i solved the problem and please suggest is there any role of abapers in this case and if yes then which concept we have to followed.This is standard program of sap so access key may be needed.So please guide me on above topics.
Regards
Shivam Pastagia.

Hi Sivam,
Sorry for asking the question to this old thread but I am having the same problem.
My requirement is also to populate the destination batch same as From Batch without allowing the user to change it.
Can you pleae let me know how did you solve it?

Why does reader freeze while opening some pdf files and others open instantaneously?

I use pdf files created from CamScanner and shared from DropBox. In DropBox, many times (over 50%) while opening the PDF the process freezes and the error message is Adobe Reader is not responding. If you close the program, and re-open the file, it opens fine. I have saved these files to my computer and the same issue occurs. The files are 100-500kb, so I do not think size is the issue. I have reinstalled Reader (11.1.10) and there is no improvement.

This appears to have reduced the time to load a document. Thanks Jimb From: Anubha Goel <[email protected]>

Facebook and add-on page does not open stuck in a infinet loop

I am able to use other ssl enabled sites like gmail from Firefox, but when I try to login to Facebook after the first page, It does not open. Have tried all the troubleshooting steps suggested for Facebook errors and https errors, no luck.
I get stuck in an infinite loop on the next page. This is the security page which asks to setup a machine name.. (https://www.facebook.com/loginnotify/setup_machine.php?next)
Please note there is no error displayed, the page just loops endlessly and does not display the Box which should ask me to set the device name for Facebook.
The same thing happens when I try the Add -ons page via the Tools menu. I am able to use Facebook in Chrome on the same system system.
Willing to work with the community to resolve this. Can also provide Wire shark dumps if required. Thank you for your time. Hope this gets resolved soon.

Difference between open loop and closed loop mode when finding the index on a stepper motor axis.

I have a test system which uses a PXI-7352 motion controller with a MID-7602 stepper motor drive to position a 200 step/revolution stepper motor with an attached 1000 line encoder. The MID-7602 is configured for 64 microsteps per step, giving 12,800 microsteps and 4000 encoder counts per revolution. The system is controlled using LabView 7.1 and NI-Motion 6.13. To home the motor, I've defined a sequence in MAX which first finds the reverse limit switch and then moves forward to the encoder index pulse.
When finding its reference in open loop mode, the system its reference at the same microstep each time. When findings its reference in closed loop mode, the system finds its reference somewhere within about a 20 microstep wide range.
I hope somebody out there with more experience with this controller can describe the difference between finding the encoder index in open loop mode and finding the encoder index in closed loop mode.
Thanks,
Mark Moss

Hello Mark,
I suspect that the behavior you are experiencing has today
with the resolution difference between your encoder and your
microstepping. Let me illustrate with an
example:
Example Setup
Stepper
Motor
NI
Motion Controller
10
steps per encoder pulse (Every 10 steps the controller gets an encoder
pulse, therefore positions 0-9 all appear to be 0 to the controller)
The
system has a maximum of 3 pull in moves set
Open Loop Scenario
The
system is commanded to go to position 9.
The
controller sends out 9 pulses.
The
motor moves to position 9.
Closed Loop Scenario
The
system is commanded to go to position 9.
The
controller sends out 9 pulses.
The
motor moves to position 9.
The
controller checks its position and sees that it is still at position 0
because it has not received an encoder pulse.
Because
the controller thinks it is still at position 0, it sends another 9 pulses
as its first pull in move.
The
motor moves to position 18.
The
controller checks its position and sees that it is at position 10 because
it has only received one encoder pulse.
Because
the controller thinks it is still at position 10, it sends1 reverse pulse
as its second pull in move.
The
motor moves to position 17.
The
controller checks its position and sees that it is at position 10 because
it has only received one encoder pulse.
Because
the controller thinks it is still at position 10, it sends and additional
single reverse pulse as its third pull in move.
The
motor moves to its final position of 16.
I believe something similar is happening with your
application as it looks for the index pulse.
Because the controller does not compensate for what it perceives as
position error in open loop mode, the motor always goes to the same commanded
position. In closed loop mode, the motor
is bouncing around inside the single index encoder pulse trying to find a
certain position.
There are several recommendations I can make towards
correcting this behavior. These
recommendations are in order of effectiveness:
Setup
your system so that there are more encoder counts per revolution than
steps per revolution.
Turn
off pull-in moves by setting them to 0 in MAX.
Use an
open loop configuration.
Play
around with the pull in window in MAX.
Regards,
Luke H

Ai read in while loop

I am acquiring data from a DAQ e series card. i intialized the daq by using AI config out side while loop . i used AI start and AI read in while loop . iam acquiring data from 5 channels. the buffer size ia 1000 and so is the scan rate in AI start.I want to save the acquired data in the file. i am also displaying data o n chart. every thing is working fine. my problem is i want to save 500 points in one seconds. for this i changed the while loop execution time by using waint until multiple sec VI and assign it 10 i was expecting that now iwll save more data point in file as now loop will execute more fast but it does not happen like this. is there any way to minimize the executing time of whil loop.i checked if i deleted AI start and AI read then loop execute very very quickly. should i place AI start and AI read out side loop but then how will it acquire data contiously. I m attaching gif file of the protion of my VI .any suggestion?

I was working quickly, and from memory, so my apologies for errors or non-clarity in my previous post. :-(
The AI START VI, should be used OUTSIDE the loop, since you only want to START the task ONCE.
When the task is complete (your WHILE loop is done), then call the AI CLEAR task to clean up (ONCE).
If you set the NUMBER OF SCANS TO ACQUIRE input to AI START to zero, that has a special meaning: acquire data indefinitely. It will not stop on it's own (assuming no errors occur), you have to explicitly stop it.
If you do this, you have to read the data often enough to avoid buffer overflow, which means the incoming data is filling up the buffer faster than you're emptying it.
I have attached a picture of the general idea. If you really want to use the CPU efficiently, then consider the shift-register idea in the picture - you process on batch of data WHILE the next batch is coming in. If you want a simpler solution, forget the shift-reg, and process it directly after reading it. If your buffer is twice the size of your processing size, you'll be OK.

Error -70006 when using stepper motor in Open Loop Mode

We have a LabView program that runs a test in which a table is rotated. At the end of the test, the table is supposed to rewind. Instead, the following message appears:
Error -7006 occurred at Read Trajectory status.flx
Possible reasons: For FlexMotion, an invalid axis number or other resource ID (Vector Space, Encoder, I/O Port, and so on) was used.
We have the PCI-7344 interfaced with a UMI-7764 and a Zeta4 that is controlling a ZETA83-93 stepper motor. There is no encoder in the system for this motor. The stepper loop mode was originally set to closed loop but the motor behaved erratically (moving multiple times when instructed by MAX to move once). The stepper loop mode was changed to open loop and the m
otor started behaving properly, but that is when the error message starting appearing. Are there any other configuration settings, such as Primary Feedback (which is now set to Encoder) or ? that I may need to correct to resolve this error?

First of all I would check a couple of things. The reason why your motor was not behaving properly in closed loop stepper configuration is most probably related to the fact that you don't have the encoder counts per revolution adn the stepper steps per revolution properly configured for your motor. Please follow the instructions found in the following knowledgebase:
http://digital.ni.com/public.nsf/websearch/29edb56146f274a386256a1c00624310?OpenDocument
When you configure an axis in closed loop stepper mode, we use the information of the encoder to generate the adequate velocity profile. If the encoder counts and steps per revolution are not properly matched, then the motor will not execute the moves properly. What you need to do is the following:
1.-Configure your axis as closed loop stepper in the Axis Conifguration Section in MAX.
2.- In thbe 1-D Interactive Basic panel, kill the motor and click on reset position.
3.- Manually rotate the motor one revolution.
4.- In the advanced panel on 1-D interactive, read the Encoder Value. This is the value you should enter on the Axis Encoder Counts per Revolution under Axis Configuration. Press Apply.
5.- Go back to the 1-D interactive Basic Panel. Change the bullet selector unbder Stepper Loop Mode from Closed to Open. Run a 10000 step move.
6.- When the move is finished, read the encoder counts from the advanced panel. This will tell you how many counts you have in 10000 steps. You can now calculate the stepper steps per revolution by the following formula:
(# of steps per count)*(# counts per revolution) = # steps per revolution.
Your motor should work fine in closed loop stepper configuration now and the error should not appear. Please make sure you are using the latest version of our driver (Ni-Motion 6.0.1)to avoid older firmware errors and fixed bugs from affecting your system. You can get it from:

Recursive Loop Error while doing standard cost estimate

SAP Gurus,
We are trying to do standard cost estimate on a material and we are getting error because it is going in recursive loop even though we have used "recursive allowed" indicator for item components in the BOM. The error message numbers are CK 730 and CK 740. We are using 4.6c. I have tried the same scenario in ECC 6.0 and still I get the same problem.
Below is my BOM structure:
Material 10890345 (has low-level code 012)
        ---> 10867220 (has low-level code 013) and has recursive allowed indicator
10867220
        ---> 10846733 (has low-level code 014) and has recursive allowed indicator
10846733
        ---> 10890345 (has low-level code 012) and has recursive allowed indicator
According to me, the BOM for material 10846733 is causing the problem.
For some weird reason while doing the costing run for material 10890345, it s not stopping and going in a loop.10890345 and 10846733 should ideally have the same low-level code as they are recursive.
Please help to provide some solutions at the earliest on how to avoid recursive loop during costing.
Regards,
Swapnil

Dear,
I have 2 things to shear with you.
The method we followed to solve the iteration is as below
1.Config change -
Valuation variant in the costing variant, we changed the sequence as below
material valuation
4 planned price 1
2 std price
3 Mov ave price
2. Material master change
made all the semi finished goods and finished goods
procurement type = E,
costing with qty structure,
Enter the planned price1
By doing this what happens is
when system first start the iteration, takes the planned price 1 and start iterating and next time in the second iteration it takes the calculated price from qty structure till it finds the difference between the value calculated is less than .001. Then it gives the result
Why lot size is important is, in our case in some levels the usage is very less compared to the first material header qty and system used to stop in between and not even reaching the last level as during the cycle it was reaching less .001 difference. may be in your case it may not be the case...just check
Please come back after trying this. this was the only last option i had to solve the issue in my client.
Another alternative is to have a different material for costing purpose to stop the iteration which i will not recommend as we need to do some calculation for each stage and input the cost of dummy material in each stage.
My client is happy with the result as the difference between manual calculation and system calculation is less then .1%...this is because SAP will not consider the difference beyond .001, but in excel you get as many as decimals you want.

Why do I get a Track out of memory error while running open loop frequency response?

MatrixX Build 61mx1411: I get a "Track out of memory" error when I run the Open Loop Frequency Response from the MatrixX pull down tools. What can I do to prevent this? We are running on an HP B1000 with 768 MB of RAM under HP-UX 10.2.

In the old days of Mx say Version 5 and prior the user actually selected the amount of memory that would be allocated. Depending on the size of the model etc. you would have to allocate memory. In version 6.0 and going forward there is no need for the user to manually allocate the memory.
Build {rstack=50000,istack=200000,sstack=50000,cstack=500 000}
If this is a command in a script file that you are running and the error is resulting from that then I would try commenting out everything after the letter d in the word build and then starting it back up.
i.e. only use Build
I don't believe that there is a way to manually allocate the initial SystemBuild Stack size.
I believe initially the stack size is set to 10010.
However, one way
you can manually set the initial SystemBuild stack size,is to create a large StateSpace as soon as you start up SystemBuild. This will prevent piece-meal reallocs while using SystemBuild.
You can created a new SuperBlock in SystemBuild and then drop down a StateSpace Block with 199 inputs and 199 Outputs and 1 State and entered ones(200,200)as the StateSpace Matrix without any problems. This would resize this internal stack to at least 40000.
You really should not have to do this but if that helps then you might think about doing this in your startup.ms file you could use SBA or load the file then you could delete the superblock and begin working.
"Bob" gave me this little tid bit.
Please let me know if any of this is of use.
