UMI 7764 with servo AND stepper

Dear Forum,
I'm working on a UMi 7764 board with a 7340 motion controller.
I want to interface 3 motors:
-axis1&axis 2 are servo drive (AKD driver & Kollmorgen motors).
-axis3 is a stepper interfaced with a SMD7610 driver.
I'have a problem with the inhibit input (S2) switch of the 7764:
for the AKD drive it should be set to Active high but for the stepper driver SMD7610 it should be Active low!
How can I find a workaround?
best regards PF

What third party drive do I use to connect my umi-7764 to a phytron stepper motor (zss66)

I would like to connect my phytron stepper motor (zss66) to my UMI-7764, do I need a third party drive ?
And if i need one, which one ?
Thank !
Seb (I am french so if you want to aswer french, let's go )

Sebastien,
l'UMI 7764 n'est qu'un bloc de connexion. En aucun cas celui ci ne délivre de puissance. Donc il vous faudra nécessaire un bloc puissance entre l'UMI et votre moteur. L'UMI 7764 ne délivre aucune puissance.
(N'oubbliez pas d'aimenter l'UMI avec une alimentation 5V externe. Ce 5V est à connecter sur le connecteur situé au debut du boitier).
National Instruments fourni des drives (MID 76XX)dont les specs sont limités en courant. (Elles sont affiché dans le lien ci dessous). Dans le cas de l'utilisation d'un drive NI, il n'est plus nécessaire d'utiliser l'UMI 7764.
Le choix de votre drive se fera en fonction du nombre de phase de votre stepper, et de son courant nominal.
Voici un lien sur lequel vous trouverez une liste de drive pour stepper. (Voir
le bas de la page web)

Je ne connais pas les spec de votre stepper, mais si vous désirez l'utiliser avec un UMI 7764, le plus simple serait de contacter la fbricant de ce moteur, et d'obtenir une liste de drive que celui conseille.

UMI-7764 with Simudrive 611 Universal

Hi there,
we`re currently trying to connect a NI UMI-7764 to a 1-axis motion system controlled by a Siemens Simudrive 611 controller.
We would be glad to find anybody providing information on how to connect both these interfaces, regarding pin alignment and/or available options.
Thanks, Ulrich

Wow, that's a manual! Almost 1000 pages...
I hope you understand, that I can't work through this huge manual, so I'll give you some general hints:
Don't forget to connect an externl +5 V power supply to the UMI-7764.
Connect the AOUTx to the +/- 10 V input of the drive
Connect the encoder signals (ENCAx, ENCBx,...) to the appropriate outputs of the drive. Please note, that the phase relation of Phase A and B are not standardized, so you may need to change the polarity of the phases in NI-MAX.
Connect the INHOUTx to an ENABLE input of the drive. This allows the NI motion controller to turn off the power of an axis completely if necessary.
Connect the limit switch inputs (FWDLIMx, HOMEx, REVLIMx) to mechanical limit switches if applicable.
These are the most important connections. Please refer to the manuals of the drive and the motion controller to find out, if the voltage levels are compatible.
Here are some more general pieces of advise:
Use the drive in torque mode. This makes tuning easier.
Here you can find help for tuning your system.
I hope this helps,

How can I measure input voltages on a 7330 board and UMI 7764 with LabView?

Hi,
I would like to use LabView with the Motion Card 7330 card. Since both are NI products I wondered if such is possible, rather than just use the NI Motion software. I would like the ability to use some VI's that I make.
Also, how can set up LabView and/or NI Motion to record voltages on the inputs? And how do I tell the card that the voltages I want to record are in the 0-10V range? I understand there are different configurations such as measuring -5 to 5 V or 0 - 10V, etc, and I just want to make sure I don't damage the card by putting in 8 V on the input, for example.
Thanks for letting me know.
Chris

Chris--
       Basically, a limit switch or a home switch is a physical sensor that sends a signal whenever the system reaches that point. So if there is a default position, or "home", then you would put one of these sensors there so that when the motor or stage is in this position the system software will recieve the signal and know. Limit switches are the same and are to prevent the system from going past the limits.
      You mentioned that you were looking in the installation guide. This is a great resource to get started but only scratches the surface. When you install the driver, NI-Motion, it will install to the programs list (Windows Start button >> Programs >> National Instruments >> NI-Motion) a directory for documentation. In this folder you can find the complete manual for motion; as well as, documentation for all of the boards. This is a default, if for some reason you don't have it these manuals can also be found online. Cross-referencing the motion and the motion controller manuals should get you most everything you need to know. If not, then a search at NI.com is also helpful. You could use the general search and select support or there is ni.com/kb for all of the knowledgebase articals There are lots of tutorials on Devzone about motion basics and programming.
     If you need anything though don't hesitate to ask!

Circuit design with UMI - 7764

Hi
I'm totally new with NI. I have to control a stepper motor using: PXI and DAQ, LabView, UMI -7764, MD10C (driver) and an example of a two-phase motor with encoder.
I've read about that kind on circuit at: http://www.ni.com/white-paper/3367/en
But I 'm not sure if I can use LabView as a motion controller. I attached my circuit diagram.
What more I have to control the motor at a specific generationstate control lines, which activate the activation key in the current motor coil. Is it possible with my hardware?

Please Disreard the above question

Doubt with encoders and UMI7774

Hi all,
I have NI, PCI7344 motion controller with UMI 7774. I am trying to read the counts of an encoder. The encoder gives 3 signals, i.e. A,B and Index. The encoder does'nt give A bar , B bar and Index bar signal. Can I still read the encoder pulses in labview with the above hardware? Is there a work around? Earlier I had UMI 7764 with PCI-7344 in my previous project. I had used this kind of encoder successfully with UMI7764. Do I need to change my encoder and get the one which gives the inverted pulses too, to use it with UMI7774.

Hi,
Hey that OK you have used 7404.But I would suggest using AM26C31 which is quadrature differential line driver.
In this particular you will give the Input and in Output you will be getting Input as well as the inverted input.i.e
If you give A as an Input , In Output you will be getting A as well as A bar.

Problem with Flexmotion 7344, UMI 7764 and servo driver parts

Hi to all of you, I've a great problem with my motion system.
This is formed by:
1.Flexmotion 7344, cable and UMI 7764 (NI-kit)
2. 2 servomotor and 2 incremental encoder
3. 2 Motor drivers
The problem is that the motor drivers (AXOR MICROSPEED) can' t work with the NI-kit, sometimes the motor go and sometimes not, so the repeatabitlity is very very low.
I work a lot trying to solve this but i suppose that the PID of the driver runs counter to the PID of the Flexmotion.
This thing was confirmed by the NI Italy staff. They tested the system and comfirmed my sensations but i had not any feedback about the type of drivers that i' ve to buy to work with my system.
I try to attach the datasheet of the motors and the encoders at the post.
If any one can help me in some ways i thank a lot. If necessary is possible to contact me by mail at [email protected]
Motor type: 17PL085
Encoder type: EH17 M500 Z 5 P 6 X 3 P R 7 8
The last important thing is that the system with this configuration of motors, encoders and drivers worked in the past with the old NI flexmotion 6C.
What we would do is to mantain this configuration of motors, encoders and drivers but substitute the old flexmotion with the new.
Thanks to all.
Andrea

Andrea-
Yes. According to the datasheet, that drive can be ordered in different versions. There are different options like control mode and feedback type. Please give us your part number. Typically, position controllers expect the drive to accept a torque reference(+/10V). It is possible to use it in velocity mode, but you need the differential option. If that is the case, then you have 2 PID loops to worry about and tune. One in the drive, and one in the controller.

Anaheim Automation stepper motor with PCI-7330 and UMI-7764

Hi, I'm fairly new to LabView 2010 and stepper motors in general. I've been trying to get an Anaheim Automation stepper motor and encoder to work with LabView with some success but it isn't quite right. My main problem is when the home switch is activated the whole thing is killed and I cannot get it to respond unless I manually turn the motor so that it is not on the home switch anymore. After that it will run ok, unless it hits the home switch again (btw if it hits the forward limit switch it will stop but it will accept a command to move away from it).
Could someone please take a look at my wiring diagram in the link below and let me know if there is anything obviously wrong with how I wired it up or if you have any suggestions on where my settings might be going wrong I'd really like to hear from you.
Thanks,
Rob

Thanks for the reply, I am trying to run any of the find reference example VIs from NI. I've not edited the code in any way.
The motors will run with the wiring I've posted, it'll move to the forward limit switch then come back again but it will then hit the home switch, the motor stops and cannot be started again until it is manually moved off the home switch. It has never made it all the way to the reverse limit switch meaning I cannot use home (it stops) or the centre (can't find the reverse limit) as a reference point.
It was suggested to me I might have the grounds miswired, the manuels were not all that clear so I'm unsure.

Configure Stepper Drive Fault indicator w/ UMI 7764 and a Kollmorgen P5000 Stepper Drive

Hi I am using a NI PXI-7352 with a UMI-7764 connected to a Kollmorgen P5000 Stepper drive Get datasheet here http://www.kollmorgen.com/en-us/products/drives/stepper/p5000-series/p5000-stepper-drive/
I have all the connections hooked up like so
P5000 UMI-7764
DISABLE IN --> INHOUT1
FLT OUT --> INHIN1
UMI active states switches are both set to Active Low.
The P5000 is disabled when a +5VDC signal is sent to the DISABLE IN line and 1 second after going LOW the drive is enabled. (not the best way to do things because if the PXI Chassis is turned off the drive becomes enabled)
When the drive faults the output goes LOW.
So my issue is that when the drive is disabled the fault goes LOW which seems to put my UMI into a continuously triggered on/off state. The drive LED flickers Green Red Green Red... and makes a high frequency noise that doesnt sound good. Can I use the Write Motion I/O Data.flx VI to configure this to work? Thanks let me know if anymore information is needed.

Using a CW230 Bi-polar driver with the UMI-7764 and 7330 PCI. But clock level is loaded below 2v and motor will not run?

I have my stepper driver connected to the +step and aogrnd terminals on the UMI-7764. With the driver connected to these terminals the output across the two is 2vp. When I disconnect the driver, the level returns to a 5vp signal. My drivers inputs are optically isolated so I suspect the impedance my be higher than TTL can drive. Is there any way to manually set the output parameters of the 7330 Motion controller?
Thx...Vic

Hi Vic,
Take a look at this KnowledgeBase: How Do I get the 73xx Controller and UMI-7764 to Drive a Third Party Stepper Motor?
I think it may have the solution to your problem. Also, here is another KnowledgeBase that is relavent:
Why Do I have to Supply Power to my UMI-7764?
I don't believe there is a way to manually set the output parameters of the 7330, but I don't think this is the source of the problem. If the KnowledgeBase articles are not the solution, post back and we'll keep troubleshooting!

NI PCI 7342 and UMI 7764

Hello All,
I am using the PCI-7342 to control 2 servos for co-ordinated motion. I am using UMI7764 to breakout Motion IO to connect to my Servo Amplifiers. I am confident that the system will work fine because I have used a similar setup before. The issue I have now is that the UMI 7764 unit is farther than 2meters from the PC. I called NI and the tech said that NI doesn't have any cables longer than 2M to solve my problem. So she directed me to this forum. I was little disappointed that NI doesn't have any option or may be she is just not aware of it.
I have following questions here. First, is it OK to have the UMI 7764 mounted farther than 2 meters from the PCI card? (I need one extra meter here) Has any one used a setup where he or she needed to mount the Break Out Board farther than 2 meters and if so than was there any issues with the signal degradation that was observed? Is there any limitation on distance mentioned any where on NI documentation ?
Secondly if it's Ok technically to be farther than 2 m than who is the cable manufacturer? I was starting to search L-com.com. Is there any other source besides L-com.
Thanks

I have a testing machine (which permits to stretch or to compress samples) that I have to analyze with an aim to re-do the processing part (command part).
I send to you a diagram of the machine and a diagram with the connection to the UMI 7764.
I have to do moving the horizontal part, obtained thanks to the rotate of the two long screws.
This screw turns thanks to the speed that supplies the motor (gearwheel + driving belt).
To control the motor, I have to apply to the terminals AOUT and AGND, the consign voltage (є [-10V; +10V]), image of the motor speed rotate.
+10V → 3000 rpm
0V → 0 rpm
-10V → -3000 rpm

How to read out a RPM signal in labview using UMI 7764 and PCI 7330

Hi
I have a problem getting a encoder signal into a labview program. The encoder is connected to a UMI 7764 motion device. This device is connected to a PC trough a PCI 7330. I heard rumors that I can't have more than two axis on a PCI 7330. But can I have more than 2 encoders on it?
The big problem is that I am new to the motion system and I don't know where to begin.
I'm going to finish a uncompleted system, but when I look at the VI, I get nervous. So you are my last hope.
I have taken screen captures of the VI and uploaded it.
My task is to implement a new encoder signal to the already-made VI.
Question is:
How do I add and read out a RPM signal from a new encoder?
VI download:

Best regards
Henrik Myhre

From your post it seems like you wants to read back the RPM value of a particular move based on your encoder. There actually is a specific VI that you can use that does exactly this. The Read Velocity in RPM.VI should output the RPM of the current move that you are doing.
In the code that you posted, it looks like you are performing a two axis move. Therefore you will need two instances of this VI, one for each axis. You should utilize these VIs within the while loop and after the move has been started that way the RPM values are continuously updated.
It also seems like you have inherited some code that looks very complicated. We would highly recommend that the you begins experimenting with basic motion to get familiar with it.

Problem with current position (UMI-7764)

Good afternoon,
I'm using servomotors PSKF321 (SEW) and servodrives MDX61B (SEW). I'm using the PCI-7344/UMI-7764 to control the motors. When I was performing some tests in MAX, I realized that I don't have feedback from axis 2, 3 and 4. Axis 1 is working fine, i can control perfectly the motor, I can make movements to different positions. I checked the connections from the drive to the UMI and they are the same that i used to axis 1. I changed to other axis and it doesn't work. I tried to change the connections from the axis2 and 3 to axis 1 they work. I tried to put in annex the xml file related to the configurations of the PCI but it wasn't accepted. It is possible that my problem is a wrong configuration of the PCI?
Thanks for your time,

Can i connect pci-7344 to my third party motor and drive without umi-7764 ?

Our Lab have NI pci-7344 motion controller and third party motor and drive made by other company.
We want to connect pci-7344 and third party motor & drive without umi-7764.
Just use cable.
Can we succeed to connect them ?

In general it is possible to connect the PCI-7344 to a motor drive without using a UMI-7764 but you will loose some safety features and the level of noise immunity for encoder signals will be decreased.
Please have a look at this link for more information.
