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,

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

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!

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-
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.

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

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!

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,

How to send an analog output signal on same axis running a stepping motor umi 7764/ PCI7334

I am running a single axis stepping motor (which is working fine) but
for the application I need to be able to turn on and off a 5 volt
laser. It notes in the manual for the UMI 7764 that the the
analog output can be used as a general-purpose voltage output. I
would like to use it as such, but can't figure out what VI's actually
send messages to the board to output a 5 Volt signal.
Ideally I would use the analog output on the same axis that the
stepping motor is on, but if need be I could use one of the other axis
if this isn't possible (ie. it may not be possible to step and send
analog voltage output on same axis at same time). I have been
looking at the configuring DAQ and ADC stuff, but can't seem to make
sense if these actually control the analog output channel. I
think they just control the Analog input channels, but maybe I am
wrong.
Any help would be greatly appreciated
Andre

Hi,
It is possible to send analog output out of the same same DAC channel in which your stepper is connected, if you configure the stepper as open loop in MAX. I've tried it. This way you have the stepper output, analog output and encoder input acting independently. So you can use these seperately for different purposes, such as using the analog output for constant speed motors where speed or position control is not of much importance, encoder for positioning some other axes and stepper output for stepper control. With good programming skills, the NI motion controllers can thus be used for the most complex configurations. Great work NI !!! Nothing is impossible.

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

UMI 7764 second axis not working

I have a strange problem with my NI motion control setup and I wondered if anyone could help me.
I have the following setup:
PCI-7330 connected to a UMI-7764
Connected to the UMI-7764 I have two P70530 stepper drives, themselves connected to two Nema-23 stepper motors with shaft encoders wired back to the UMI-7764. All following the manual.
The 'Inhibit Input' switch is set to active high and the 'Inhibit output' switch is set to active low.
Both P70530 drives initialise (solid green LED). The stepper drive and motor connected via the 'Axis 1' terminals of the UMI-7764 works fine. The second one, connected via the 'Axis 2' terminals does not. When I attempt to start a motion via MAX, the motor audibly "clicks" once and then disengages. The drive then has a flashing green LED.
The motor will remain disengaged until I attempt a motion in the opposite direction, at which point the same "click" is heard and the motor is now engaged. No motion other than the vibration caused by the motor engaging/disengaging occurs.
Both drives and encoders are wired identically into the UMI. I have switched the cables with the drive that works, as well as the drives themselves and even the motors. The result is always the same; the drive/motor wired to 'Axis 1' works fine and 'Axis 2' "clicks" but doesn't move.
I'd appreciate any advice or suggestions anyone can provide, please.

A bit more information in case anyone can help me:
Repeating the attempted motions in MAX for each axis I probed the poles of the UMI connected to the stepper drive. The results are below.
The Inhibit Input of Axis 2 seems to be always at 5V.
The 'Inhibit Input' switch on the UMI is set to active high and the 'Inhibit output' switch is set to active low. I would have expected, therefore, that reversing these switches would make Axis 1 stop working and Axis 2 start working. However, when I did this Axis 1 stopped working but Axis 2 continued the same behaviour (i.e. any attempted motion causes the motor to "click" and then disengage).
I also attempted to reverse the Inhibit Input action via MAX, but the option is greyed out.
Is there any reason why Axis 2 would be forced into having Inhibit Input at 5V? And, more to the point, is there a setting to stop it happening, or is this a hardware failure?

How to connect the UMI-7764 to a geared motor

Please, I have simply to connect a geared motor to the UMI-7764 thru an L293D driver.
Please, could you tell me which outputs of the UMI-7764 do I have to connect to the driver ?
Thank you.

You'll need to refer to the documentation for the L293D driver to determine which lines it need attached. For servo motors you typically atach the Analog Out line as well as the Encoder feed back lines from the UMI. For steppers, you need to at least wire the step and direction lines to your drive. I recommend taking a look at the 7764 user manual as well for help with wiring.

What is /INHIN1 terminal in the UMI-7764? It's not in the 7344 HW user manual.

What is the purpose of the /INHIN1 terminal and how does it relate to the Inhibit Output signal?

The basic purpose of the inhibit circuitry is to shut down the drive and inform other components in the system if a fault is detected. The UMI-7764 has circuitry onboard that will OR together four different sources of inhibits; the per axis controller inhibits, the per axis external inhibits (INHINx), the external inhibit all (INHALL), and the host bus interlock. You can use the INHINx lines to shut down an individual axis or the INHALL line to shut down all axes. These are typically wired to the "fault" output of the drive(s) you are using. When the UMI detects an inhibit from any of the four sources, then it will generate an inhibit signal on the INHOUTx lines. The INHOUTx lines are generally connected to the "enable" inputs on the drive(s). The polarity o
f the INHINx and INHOUTx lines is configurable using the switches on the UMI.
Do not simply tie any of these signals high or low with a jumper. Failure to properly connect the inhibit/enable signals can cause (and has caused) expensive damage to your motion system.

Is possible to give a 5V input to the umi 7764 connector blick for the limit switch inputs

I am using a umi7764 connector block for my 7344 controller. My motion control hardware provides me a 5V output in case the limit switches are enabled. But the umi 7764 connector block connections for the limit swithces are in such a way that it doesnt get any input, instead it has to be directly connected to the limit switches.Is there any way to come around this problem so that the limit switch inputs read the 5v given out by my motion control appplcation

If your drive has individual outputs for the forward, reverse, and home switches, then you could connect these to the their respective terminals on the UMI. You will need to either disable limit functionality on one component (controller or drive) or make sure the limit behavior for the devices does not conflict with each other. It probably is best if the controller handles the limits, but this will depend on your application.
If the drive only has one output to indicate that one of the switches has been activated, then you have fewer options. In this case, you should probably just use the limit protection on the drive and poll that single output with another input on the UMI.

Can I re-direct the output of a UMI-7764 AO to another board (6233) AO?

I have an existing application which I am trying to update to isolate
the motor / encoder / servo amplifier from PC ground. To this end
I have installed opto-isolation circuitry and power isolation on the
UMI-7764 to isolate my digital IO signals. I still have a leakage
path from the AO on the 7764 to the servo amplifier. I do have a
PCI-6233 in this setup, used for measuring isolated analog
signals. Is it possible to modify my labview control software to
re-direct the AO from the 7764 to the 7233 AO to isolate the signal
using the Configure Axes Resources.flx? Otherwise a hardware
route will need to be taken using an isolation amplifier (not
preferred).
Thanks in advance for any insight.
-Stefan

Hi Stefan,
Unfortunately you will not be able to route the AO Ground through your 6233 if you are using our FlexMotion subVIs. These VIs have been specially designed to work with our Motion Controller cards so will only communicate with them. You mention using our UMI 7764, that is simply a breakout box, which motion controller card are you using?
Also, what are you using to confirm that the AO Ground is 'leaking'?
