Umi 7774 required for ni drives?

i am designing a motion control system using 3 stepper motors (ni Nema 23) and correspondingly 3 ni P70360 drives. Is a umi 7774 required to connect these to the 4 axes pci motion controller card? (i'm confused as its description on the ni site says that it is required for 3rd party drives BUT in the discussions i've read a lot of people have used umi 7774 with ni drives )

Hello aks,
Yes, you will need to purchase and use our Universal Motion Interface (UMI) 7774 board in order to connect the three drives/motors to the motion controller card.
It may have been confusing because we do explicitly say that it is required for 3rd party drives, but not necessarily required for our drives. Having said that, the vast majority of customers use the UMI board because it eliminates the need for custom cables, and makes it far easier to connect to more than one axis.
Here are some links that may provide more detail and could prove to be helpful.

UMI - 7774 connectng to servo drive problems

Hi, I am using a UMI 7774 motion interface to control a Parker Servo drive (AR-08SE). The Servo Drive requires a differential input for the step and direction signals so I followed this wiring diagram. (http://www.parkermotion.com/scripts/support_faq.asp?rowid=AAAH0UAAKAABvpjAAD&count=1&random_number=1...) I am using MAX to operate the system but I can not get the servo motor to operate. It has holding torque but will not turn when I command it to. I get a "motor off (axis is killed)" and "following error occured" message. Am I missing something in the software setup? Or is it a wiring issue?
Thanks, jdb

This could be a wiring issue (e. g. interchanged encoder phases), but there are also other potential reasons. Please refer to this document in the NI knowledge base for further troubleshooting information.

Mor,
Ok. I had to download the manual for your device, but I think I can help you out.
1. Do you have the 9 pin D-Sub connector that provides the Auxilary Incremental Encoder, or do you have the 15 pin D-Sub connector for the sinusoidal commutation, or do you have both? I would recommend the Auxilary Incremental Encoder if possible. I need to know which one you have in order to help you completely setup your system.
2. You need to connect pin 3 of the drive to pin 1 of the Axis 1 Control connector on the UMI.
3. You need to connect pin 4 of the drive to pin 9 of the Axis 1 Control connector on the UMI.
4. You need to connect pin 4 of the drive to pin 8 of the drive.
5. You will need to change the settings on the drive so that it know you are in Torque mode instead of velocity mode (CP.10).
6. Depending on what you are going to use for feedback (Auxilary Incremental Encoder/Sinusoidal Commutation) you will need to hook the proper D-Sub connecter to the UMI, the instructions on how to do this can be found in the 735x user manual, which can be found through the link below...
http://www.ni.com/pdf/manuals/371060a.pdf
NOTE: I recommend you use the Auxilary Incremental Encoder if possible, it is easier to use and setup. If you do not have both the Auzilary Incremental Encoder and the Sinusoidal Commutation, then you will need to purchase it for your drive. Attached is an excerpt from the manual showing what I am talking about.
I hope this helps,

Requirements for JDBC Driver needed for SOA 8 }connection pool

Hi,
I have an AS400 jdbc driver. This driver is JDBC API version 2.x. Also is a Driver Type 4.
What are the requirements of a JDBC Driver needed for connection pool in SOA 8?
Thanks.
Lorenzo Jimenez

You can use pretty much any jdbc driver, including type 2 and type 4.
You need to make sure your shared libraries needed by the driver are available to the appserver when you boot.
Other than that, it is no different than configuring any other driver.

Help Required for format drives on SAN

Hello Guys,
We want to create new RAC database in the currently Oracle 11g R1 environment. We already have a RAC databases having 2 instances. Each instance is on separate nodes
Network/system administrator has provided additional storage which currently can’t be seen through MyComputer on Windows
Looking the drives from Windows Computer Management from node 1 and while trying to format and could be seen in Windows MyComputer, the primary partition option in select partition type is disable. Only logical drive partition could be selected
Whereas while drive from Windows Computer Management from node 2 and while trying to format. The primary partition option could be selected.
My current understanding is we need to format the drive using primary partition option only for Oracle RAC.
Please guide me

Ppd required for postscript driver for frequency lpi print changes

Hello,I need a PPD to support my postscript driver for frequency lpi document print changes.I am running hp pav dv9000 with hp laserjet p2015n
and illustrator cs3,have tried so many things but still belive it must be something so simple either the wrong PPD or a setting in cs3.I can offer further information if anyone can help.

Locate the PPD-file by a windows search for *.PPD.
Open by WordPad and and check by reading the header whether
it's the correct one.
A PPD can have several names (file name, internal name,
nickname, for instance, but all are in plain ASCII).
When the PPD is identified, then print the relevant parts
about screens (Lpi,dpi) on paper.
Use in the settings only Lpi/dpi combinations which are
mentioned in the PPD.
I'm not sure whether other combinations are simply ignored
or replaced by the nearest parameters in the PPD.
This may depend on the printer.
I had tested 1200dpi toner printers by 90/100/120Lpi.
The results were different, accurate measurement was not
possible.
90Lpi delivers less geometric resolution, but more levels.
Good for smooth gradients, as in portraits.

Connecting Yaskawa Sigma II Servo Drive (SGDH) to PCI-7344 and UMI-7774

Hi,
I have NI PCI-7344 and UMI-7774 and i want to
Connect the UMI-7774 to Yaskawa Sigma II Servo Drive (SGDH) , the servo motor drive is connected to the servo motor with original Yaskawa cables.
1.  do you know if National instruments provide special cables to connect the UMI-7774 to the Yaskawa Sigma II Servo Drive (SGDH) ?
     i know there is special cable to connect this servo drive to the NI PCI-7390
     http://zone.ni.com/devzone/cda/tut/p/id/5908
(you can find in this link that this cable exist: 50 Pin cable for connecting MCA-7790Y to Yaskawa Sigma II Servo Amplifier)
     but this is not the case here, i need to connect the Servo Drive to the UMI-7774..
2. Where can i find a tutorial on how to configure the PCI-7344 in MAX to send simple commands to the Servo Drive
      i.e. to run the servo motor from position A to position B (10,000 encoder pulses)
i'll be gratefull for any help
Regards
Moti

Hi MotiM,
We do not have a cable that will let you directly connect the UMI-7774 to a Yaskawa Drive. We do sell cables that will have the Dsub connector to match the UMI-7774 with pigtails to wire to the drive. If you take a look at the product page for the UMI-7774 you can see the different cables listed under the accessories.
To perform a simple move in Measurement and Automation (MAX) is very simple. In MAX under NI-Motion select your PCI-7344. Under this section select the settings option (by default it will be called Default 7340 settings). Select the Servo radio button. Initialize your controller. Then you can select Interactive and 1-D Interactive and command your motor from there. I have attached an image with the important areas highlighted for you.

Windows update requirements for Xerox print drivers on Windows 2003 server

Hello, We are currently deploying a fleet of Xerox MFD's across ~100 locations, and we are running into an issue installing the print drivers on some Windows Server 2003 (32bit) boxes. (both the machine specific driver, as well as the Xerox Global print driver) The print driver installs fine, but no jobs will actually print, and if you try and print a test page, an error "Test page failed to print. Would you like to view the print troubleshooter for assistance?" comes up instantly. We have seem to have narrowed the problem down to a missing Windows update, as if we do all available High Priority and Optional updates, it starts to work fine. Does anybody know specifically which Windows updates are a requirement for the driver? Our 2003 servers were last fully updated about a year ago, and due to time constraints, if we could just install the Windows updates that are needed it would be a big help. Thank you in advance

When Xerox dropped support for XP, they stopped adding particular files from the driver packs (probably for size reduction) because they were all included by default in every newer OS. If you install this here on any XP/2003 base machines it will work as normal. It is best to install that before the driver install, but I have been mostly lucky to have it work fine days later. YMMV

System Requirements for Running Cloud at home?

I teach film production and would like to have access to Creative Cloud at home, so I can brush up on all the programs having recently transitioned from Final Cut Pro. My home computer is pretty basic and its a PC. What are the minimum system requirements for Hard Drive, Video Card and Ram? Do I download the programs onto my pc or do I use them in the cloud, thereby saving my precious, and tiny hard drive?

You misunderstand. Even in Creative Cloud the programs install locally. It's merely a different licensing and distribution model. For the requirements, refer to the producrt pages of the individual products like here:

UMI-7774 Axis1 Inhibit input/output (and Fault +/-) to corresponding Servo Drive signals

Hi,
I have servo drive (yaskawa sigma fsp) that i configured to work in Position command mode,
And i want to connect it to UMI-7774 with PCI-7344 also configured in MAX to work in P-Command mode.
The Servo drive has these signals:
/S-ON   (Servo ON input)
ALM+   (Servo alarm output)
ALM     (Servo alarm output)
The UMI-7774 on its Control Connector of Axis1 has these signals:
Enable
Fault+
Fault-
i read the umi7774 manual and also the servo drive manual, and didnt understand all the things because
the umi7774 manual named the signals Inhibit-input, inhibit-output
but there is no signals in this name on the UMI-7774/Axis1/Control Connector.
So, i think the wiring i need to make is :
[Servo Drive] /S-ON   < to >  [UMI-7774/Axis1/Control Connector] Enable
[Servo Drive] ALM+   < to > [UMI-7774/Axis1/Control Connector] Fault+
[Servo Drive] ALM      < to > [UMI-7774/Axis1/Control Connector] Fault-
is [UMI-7774/Axis1/Control Connector] Enable is same as Inhibit-Output ?
what about the inhibit-input, is the ALM+ from the drive is acting this role ?
And, because the servo drive and the pci7344 configured to P-Command (Position command) mode,
The control signals is connected in this way :
[Servo Drive] PULS      < to > [UMI-7774/Axis1/Control Connector] Step (CW)
[Servo Drive] /PULS     < to > [UMI-7774/Axis1/Control Connector] Digital Ground
[Servo Drive] SIGN       < to > [UMI-7774/Axis1/Control Connector] Dir (CCW)
[Servo Drive] /SIGN      < to > [UMI-7774/Axis1/Control Connector] Digital Ground
And for the feedback connector :
[Servo Drive] PAO      < to > [UMI-7774/Axis1/Control Connector] Encoder Phase A
[Servo Drive] /PAO      < to > [UMI-7774/Axis1/Control Connector] Encoder Phase A-
[Servo Drive] PBO      < to > [UMI-7774/Axis1/Control Connector] Encoder Phase B
[Servo Drive] /PBO      < to > [UMI-7774/Axis1/Control Connector] Encoder Phase B-
[Servo Drive] PCO      < to > [UMI-7774/Axis1/Control Connector] Encoder Index
[Servo Drive] /PCO      < to > [UMI-7774/Axis1/Control Connector] Encoder Index-
i read the ni-motion manual,pci-7344 and umi7774 manual and also the articles about configuring the Position Command mode
including the MAX setting.
i finally start to understand the setting after i read the PCI7390 which is position-comannd controller.
i just need to know if what i write here is correct.
(The servo drive manual is here:
  http://www.yaskawa.com/site/products.nsf/products/Servo%20Amplifiers~fspsigma.html?openDocument&seq=... )
Last thing, the "How to connect the 73xx inhibit and command signal outputs to third party drives" article
(http://zone.ni.com/devzone/cda/tut/p/id/3442 )
shows that we need resistors etc.. to connect the signals between the servo drive and umi-7774,
can i directly connect the signals using Pigtail cables the National instruments provide?
Thanks
Moti

Dear Vince,
this is the description from the servo drive manual about the following signals:
[Servo Drive] PULS (Reference pulse input)
[Servo Drive] SIGN   (Reference pulse input)
[Servo Drive] PAO   (PG divided output A-phase) same for PBO,PCO
i understand the following connection that i write here (for control and feedback)
from the PCI 7390 users manual (Table B-7 on Page B-15 : CN1 cable pin assignments)
the table shows the signals from the MCA-7790Y which is accessory
for connecting the pci7390 to Yaskawa Sigma 2 drive (which is the same as Yaskawa Sigma FSP drive).
So, is that the correct connections for using the umi7774 and this servo drive in position command mode ? :
[Servo Drive] PULS      < to > [UMI-7774/Axis1/Control Connector] Step (CW)
[Servo Drive] /PULS     < to > [UMI-7774/Axis1/Control Connector] Digital Ground
[Servo Drive] SIGN       < to > [UMI-7774/Axis1/Control Connector] Dir (CCW)
[Servo Drive] /SIGN      < to > [UMI-7774/Axis1/Control Connector] Digital Ground
And for the feedback connector :
[Servo Drive] PAO      < to > [UMI-7774/Axis1/Control Connector] Encoder Phase A
[Servo Drive] /PAO      < to > [UMI-7774/Axis1/Control Connector] Encoder Phase A-
[Servo Drive] PBO      < to > [UMI-7774/Axis1/Control Connector] Encoder Phase B
[Servo Drive] /PBO      < to > [UMI-7774/Axis1/Control Connector] Encoder Phase B-
[Servo Drive] PCO      < to > [UMI-7774/Axis1/Control Connector] Encoder Index
[Servo Drive] /PCO      < to > [UMI-7774/Axis1/Control Connector] Encoder Index-
thanks for your reply , i appreciate your help
since i'm alone in this, unfortunately i cant get help on this issue from anyone.
Please verify that what i write here is correct.

Connecting Yaskawa Sigma FSP Motor Drive With UMI-7774 and PCI-7344

Hi,
i have PCI-7344 and UMI-7774 that i want to connect to this Servo motor drive of Yaskawa.
1) How do i know if this motor drive is compatible with the pci-7344 and umi7774 ?
     for example: inside the UMI manual is written that the Motor drive must support "Sinusoidal Commutation"
     i look indside the Motor Drive manual and i dont found anything about this.
     this is link to the motor drive:

     http://www.yaskawa.com/site/products.nsf/products/Servo%20Amplifiers~fspsigma.html?openDocument&seq=...
2) How do i connect the feedback and control lines from the UMI to the Motor drive?
i'll appreciate any help including posting a link to a tutorial that helps to understand the signals from the motor drive and the encoder
And also the umi-7344 (Phase A, Phase B, Hall sensor, inhibit, Fault, etc... )
Some powerpoint or Pdf tutorial that National instruments provide will help as well.
P.S. i read the manual of the UMI-7774 and the pci7344 manual, but i'm yet not understand what i need to do
in order to configure my motion system :
PCI-7344 , UMI-7774 , Motor Drive (Sigma FSP Yaskawa) , Servo Motor (Yaskawa)

Connecting Parker Compax3 servo drive to umi-7774, and PCI-7340

Im very new to NI motion control products, and was wondering if anyone knew of the specific details for connecting a Parker Compax3 servo drive to the UMI-7774 and motion controller PCI-7340. Any connection diagrams and software set-up would be very helpful
Thanks,

Hey Scott,
I don't have any specific documentation for the Parker Compax3. The best I can do is give you links to the manuals for your hardware.
UMI-7774
PCI-7340
Parker Compax3
The pinout specifications for each device are there in the manuals, it should just be a matter of matching them up. If you have some more specific questions about getting them set up, I'd be happy to provide any assistance that I can. Have a great evening!

Connecting NI-7358 and UMI-7774 to a sinusoidal commutation driver

Hello,
I'm using NI-7358 PCI motion control card and UMI-7774 to drive a brushless servo motor driver Advanced Motion Controls S16A8 External Sine Commutation driver. (It doesn't have isolated ground.)
It's inhibit input like below:
                                ^ 5V
                                 |
                                 >
                                < 10K
                                 |
(-INH / EN ) o----------------> to control logic
GND              o----------------
                                              |
UMI's inhibit output is connected the drivers inhibit input directly. But there is something wrong with this connection. Control card's inhibit output always stays energized so that driver always stays disabled. (When inhibit input is connected to ground directly it's working properly)
When inhibit signal is active (axis is killed) UMI's inhibit output is 3.5V.
When inhibit is deactived (axis is started) UMI's inhibit output is 4.9V.
NI7358 inhibit is configured active low
UMI 7774 is configured active low
Driver is configured as active low.
I tried both open collector and totem pole configurations of NI7358. Results were the same.
Could you help me please.
Kind regards...
PS: AMC driver's manual: http://www.a-m-c.com/download/datasheet/s16a8.pdf

Hello,
>>1. What do the lights on the UMI indicate when you change the Inhibit Output Settings in MAX (enabled or disabled)? When you change these settings make sure you initialize the drive after changes.
inhibit disabled from MAX ------>   UMI Disable led is always on
inhibit enabled from MAX ------->   UMI Disable led is on when axis is killed
                                                 UMI Disable led is off when axis is started
>>2. If you have the drive inhibit line connected directly from the UMI to the drive what are the results of changing these inhibit output settings? Are there any LEDs on the drive to indicate if it is enabled or not?
When the inhibit line is connected to drive directly, it's enable led is always red (it means disable) since it configured as active low. When I change its polarity to active high it always indicates green (enabled) whether the UMI's inhibit line is low or high.
When inhibit signal is active (axis is killed) UMI's inhibit output is 3.5V. When inhibit is deactived (axis is started) UMI's inhibit output is 4.9V.
>>3. What happens if you reverse the polarity in MAX and/or the UMI?
Drive is always green or red according to drive's inhibit polarity.
