Why does not my servo motor work?

Hello all,
I can work my servo motors, so I have two questions.
Firstly, I'm using PXI-7340 & UMI 7764 to control AC motor on servo motor (TAMAGAWA SEIKI co.),
But in MAX, motor doesn't work with servo type.And there is no signal between AnalogOutput and AnalogOutputGround.
Can I connect UMI to the motor correctly?
Now, I connect encorder signals with changing differential line driver (motor driver) to TTL (UMI) using quadruple differential line receiver.
Is it right?
If it is right, why does the motor work?
Secondarily, when I use stepper type in MAX, the motor work with open-loop. But when I use stepper type in MAX, the motor doesn't work with cloosed-loop.Why?
Polarities of encorders(A, B, Index) make matches my servo motors by setting in MAX.
Why?
Thanks,
megumi

Thank you for your reply.
The "does not work" means that the motor doesn't move with servo type.
In MAX, there is no error when a target position is less than 999 in 1-D Interactive, but doesn't move. When the target position is more than 1000 and I click "Apply" and "Start", error ramps of "Motor off" and "Following error occurred" are red. And the motor doesn't move.
I thought that firstly signals of encorder have been wrong because the motor have not moved with stepper mode of closed-loop and feedback of encorder.
So I would connect correctly wiring of encorders, but the motor doesn't move.
Wiring of all is "STEP", "DIR", "AO", "ENC A, B and Index bar" respectively. In MAX, type is servo mode, feedback is encorder, kinds of limit switch are not used.
I supply it if you need the other setup of wiring or information.

Why does not open(fileObj,rawOpt); work properly?

Hi!
I'm trying to open a RAW file without header, so I want to say to Photoshop what dimensions I want. This is my idea:
var filename = File.openDialog("RAW");
if (filename) {
var rawOpt = new CameraRAWOpenOptions();
rawOpt.settings = CameraRAWSettingsType.CAMERA;
var fileObj = new File(filename);
rawOpt.bitsPerChannel = BitsPerChannelType.EIGHT;
rawOpt.width=30;
rawOpt.height=1000;
rawOpt.channelNumber=3;
docRef = open(fileObj,rawOpt);
But my Photoshop CS2 fails telling me that docRef = open(fileObj,rawOpt); is not implented.
However, if I use open(fileObj) it works, but it shows me a dialog to insert dimensions and I don't like that.
Any idea/suggestion?
Thanks a lot for your time.
BTW. I inserted this question in the wrong forum before, so now I put it here. Sorry for any inconvenience.

Why does not USB flash card work?

MacBook Pro 13' (late 2011)
OS X Yosemite 10.10
My USB hub does not see any flash card, but it works when I use my iPhone.
What have I done: I tried to open my flash card. Then, I cleaned my flash card with Disk Utility and tried to connect to Mac again. I also tried to use different flash cards. But there was no effect.

Thank you for your reply.

Why does not my iPhone 5S work on LTE of Plus GSM network in Poland although my model supports LTE Band 3?

am My iPhone 5S does not support LTE of the Plus GSM network in Poland? It works in Band 3 and my model supports that band but it is not possible to use LTE although it works on my other Android phone. The network operator suggested contacting Apple.

Thank yo Tim, but actually I beg to disagree with you about that I chose to use the wrong carrier. But I have not given all details of the story:
When I was buying the iPhone at an Apple store in the US I explicitly asked whether LTE would work on my network in Poland,which uses LTE Band 3. She was very nice and checked something in the specifications and said that the model I would buy supports this band so that everything would be fine.
Unfortunately back in the country it turns out it does not work not and I expect Apple to take a stand on that. I have already filed a complaint on Apple helpline. I hope they will solve the problem...

Why does not my hdmi kabel work from my iMac to my receiver?

I have bought a new HDMI kabel, the last one worked fine. But i needed a longer one this time. And now I dont get picture nor sound on my TV??? Help!

Apparently an HDMI cable over 50 feet in length will begin to suffer signal degradation. Does this apply in your case?
Hope this helps

Why does not drag and drop work?!

Hello,
I am trying to implent a drag and drop from a table to an icon representing a trash.
The drop handler fails in converting the selected rows to a list:
com.sun.el.MethodExpressionImpl@87d9c00d javax.el.ELException: java.lang.ClassCastException: java.lang.String cannot be cast to java.util.List
Could you help me to understand why? Below are the details.
This is the af:table:
<af:table var="row" rowBandingInterval="0" id="t1"
value="#{bindings.MyView1.collectionModel}"
rowSelection="multiple"
columnStretching="last"
horizontalGridVisible="false"
verticalGridVisible="false" fetchSize="-1"
autoHeightRows="6" width="190"
disableColumnReordering="true">
<af:column sortable="true" headerText="Entry" id="c1"
align="start">
<af:outputText value="#{row.Description}" id="ot1"/>
</af:column>
<af:dragSource actions="MOVE" defaultAction="MOVE"
discriminant="delete"/>
</af:table>
This is the drop area:
<af:image source="Images/empty_trash_32.png" id="i2">
<af:dropTarget dropListener="#{backingBeanScope.DropHandlerBean.dropHandler}"
actions="MOVE">
<af:dataFlavor flavorClass="org.apache.myfaces.trinidad.model.RowKeySet"
discriminant="delete"/>
</af:dropTarget>
</af:image>
This is the failing listener listener (the failing point is bold):
public DnDAction dropHandler(DropEvent dropEvent) {
DnDAction dnda = DnDAction.NONE;
if (dropEvent.getProposedAction() == DnDAction.MOVE) { // delete
RichTable table = (RichTable)dropEvent.getDragComponent();
//determine the rows that are dragged over
Transferable t = dropEvent.getTransferable();
//when looking for data, use the same discriminator as defined
//on the drag source
DataFlavor<RowKeySet> df =
DataFlavor.getDataFlavor(RowKeySet.class, "delete");
RowKeySet rks = t.getData(df);
if (rks == null) {
return DnDAction.NONE;
Iterator iter = rks.iterator();
while (iter.hasNext()) {
//get next selected row key
System.out.println(rks.toArray().length); // the number of selected rows is ok
List key = (List)iter.next(); // here gives: java.lang.ClassCastException: java.lang.String cannot be cast to java.util.List
//make row current so we can access it
table.setRowKey(key);
//the table model represents its row by the ADF binding class,
//which is JUCtrlHierNodeBinding
JUCtrlHierNodeBinding rowBinding =
(JUCtrlHierNodeBinding)table.getRowData();
Row row = (Row)rowBinding.getRow();
//delete row;
row.remove();
//activate animation
dnda = DnDAction.MOVE;
return dnda;
thanks.

I did try, I obtained this:
java.lang.NullPointerException
Why NullPointerException?
I don't know if this helps, but consider that the collection model comes from a ViewObject built on three EOs with many fields, although the table only shows one column.
This is the Iterator in my pageDef:
<table IterBinding="MyView1Iterator" id="MyView1">
<AttrNames>
<Item Value="Cod1"/>
<Item Value="Cod2"/>
<Item Value="Cod3"/>
<Item Value="Cod4"/>
<Item Value="Description"/>
<Item Value="Cod5"/>
</AttrNames>
</table>
Any idea?
I will see the Key content with the debugger.

Why does not my Pages app work?

I have got a problem with Pages. Since I have been using the IWork for many years, I am aware how to do it. Now I updated the apps and I can not open it when I turn on the ICloud. There is no problem with Keynote and numbers. Only the Pages.
When I try to open it, disappears.
Thanks

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased.

Why does my php export feature work in IE and not firefox?

Why does my php export feature work in IE and not Firefox? I've written a web application which contains a SigmaGrid. The grid controls reload, add update delete, print and export to csv all work in IE8. The export feature does not work in Firefox.

I'm not sure what's going on for you. I've had 4 other developers - two on Comcast and two on Fios review my work and they get the control and export action in the IE8 version but not the FF10 version.
Thanks for looking into this for me, though. I appreciate the effort. '' The operation was a success doctor, but the patient died.''

Why the mouse pointer in Logic Pro does not change shape during work in OSX 10.9.1?

I've a MacBook Pro Retina 15-inch Late 2013 and I'm using two external displays. One connected to to the HDMI port (display 1) the other to thunderbolt (display 2). The MacBook display is closed. I’m working with Logic Pro 9.1.8 (32bit) with OSX 10.9.1
Why the mouse pointer in Logic Pro does not change shape during work???
It was already difficult with OSX 10.9 but now after upgrading to 10.9.1 it's game over!
At least before I could select which display use Logic Pro to have all the shape functions of the pointer. Not in both displays, so to be forced to edit in ONLY ONE of the two displays using this workaround: (right click on Logic icon in Dock: Option --> Desktop on Display 1). Now or I select “Option --> All Desktops” or does not work. However, by selecting all displays you say goodbye to Mission Control. This can’t be a solution!!!
The amazing thing is that Nuendo has no problem while Logic Pro, Apple's native software, it can't!
With Nuendo it’s indifferent in which display you are working, the shape of the mouse pointer changes shape depending on the requirement in both displays.
This thing drives me crazy!
Solutions?
Here some ideas in other foums:
http://www.logicprohelp.com/forum/viewtopic.php?f=1&t=86264
But this aren't really solutions but workarounds. Use Logic in all desktops makes Mission Control useless!!

I installed all over again by formatting as suggested by the genes of pro application support. Each plug-in, each virtual instrument, a job that lasted 3 days. And as suggested for each new plug-in I proceeded to check the proper functioning of Logic Pro and did each time a back up with Time Machine.
The Result:
Logic works as it should ONLY on the primary monitor and ONLY on the first desktop.
BUT
Reason and Nuendo dont' have this issue !!
I believe that Apple developers are thinking only to mobile phones and things like messages or face time.
And that's not all!
After a few weeks, perhaps by installing a version of Adobe Acrobat, I say maybe because I'm not sure, logic has stopped working properly. Again problems with the mouse pointer.
Luckily I had a back up! But now I'm terrified to install new programs. Thanks Apple!

HT4053 How do I delete photos, the delete button does not appear to be working?

I have downloaded all my photos to my new IPad. I need to delete some I do not want, how do I do it. The delete button does not appear to be working?

I personally don't know of any other software that does syncing, however, you can use another cloud service like Dropbox or Flikr to house your photos, add and delete them and have them available for viewing on any device or comuter that has an internet connection.
I'm not sure why you would be having trouble not getting photos that you put into your Photo Stream Uploads folder on your iPad. Photo Stream is Photo Stream. Also, just so you know, photo management and Photo Stream have nothing to do with iTunes. Photo management on the computer is done through your photos folder and app (on a Mac, it's iPhoto). You only use iTunes to tell the sync process which items to retrieve and sync from that library. Photo Stream is completely independent of iTunes altogether.
If you want to get photos from a camera to your iPad without having to use a computer, get a camera connection kit which will allow you to physically hook the camera to the iPad, and to directly download the photos from the camera to the iPad.
You would still want to also hook the camera up to the computer to back those photos up to your photo library on your computer.
Also you might want to look into purchasing (for under $5) iPhoto for your iPad:
https://itunes.apple.com/us/app/iphoto/id497786065?mt=8
Seems like you might benefit from talking to your local Apple Store about when they might have some sessions for learning photo management and sharing between your device and computer, because what you appear to be wanting to do is all do-able. I guess I'm just missing what your issue is. You can many things with photos on your iPad, however, your device will never be a substitue for your computer for backing up and managing your photos.
So, best of luck, I hope one of the suggestions above will help you to achieve what you are trying to do.
Cheers,
GB
