The first question I have is can you integrate the stepper configuration utility into labview, or do they have to be used as two separate programs? The second thing I am wondering, is what is the step resolution for the motors? I am wanting to create a hardware timed system, that would create at least 8192 samples, so wondering if I would need a reference encoder, or if the NI stepper can have that small of steps.

Couple questions regarding NI integrated stepper and drive

What is the speed control logic within NI9514?
Hi guys,
I'm using NI9514 to control a servo mortor, but the control logic just confuses me. I used Straight-Line-Move block to give a certain velocity to motor and the motor does follow the velocity(though with oscillation in a small amplitude). But what's strange is that there is no velocity control loop in the axis configuration, so what is the real thing that's controlling the speed? Is it that the velocity just got integrated to position? The axis configuration is listed as below. Any reply is appreciated!
Best Regards

How to send a step with AKD EtherCAT
Hi,
I'm working with a cRIO and softmotion I would like to know how to send a Step to my Engine via AKD. In my tools of Softmotion I have several type of move (Line, Arc, Contour) but I don't have a Step. Thanks for your answer

Home switch control during simulation
Hello,
I am trying to control Softmotion simulated axis and I am struggling to work with Find home express VI. I have found a nice example project called Reference Move - Home and index. My problem is, that I am not able to manually control state of home switch.
I have tried invoke node - axis interface - write data. But with negative result. (Also, I found out, I have to wire all of the inputs of the invoke node but I only need to control the Limits/Home status.) I have enabled the home switch in axis properties and set it to simulated.
Thanks for any help.

Agilis-P Controller (Model CONEX-AGP)
Dear All,
We have bought a linear satge (AG-LS25-27P) with Agilis-P Controller (Model CONEX-AGP). I have an inquiry regarding the VIs (labview) of the controller. Thereshould be several VIs to control the motion, step size, move, etc. MY question is: where I can find this VIs? I have tried to search for them on the company website but find nothing. Could you help on this.
Best regards,

Reserved pins in NI9514
Hi guys,
I found that there're many reserved pins in module NI9514. Is there any way that reserved pins can be programmatically changed to a analog output or anything like that? Many thanks in advance!

Why write express vi does not work while line do?
Hi,
I'm using NI9514 to control a motor drive. When I was building the VI I found that the straight line move works while the write(with either velocity or position) won't do anything. I've read about the detailed help about it and still have no idea, and there's no such example in my LabVIEW example library as it suggested. Does anyone have idea? Thanks for any help!

Breakpoint Pin Axis Assignments PXI 7354
Hello,
I've had a customer dig a legacy project up from the dead and I am looking for a bit of information on the PXI-7354 / UMI 7774 combo with regards to Breakpoint
First I should say that the code is all working, I am just looking to tidy up some paperwork.
I am using (successfully) breakpoints on Axis 2. I have to document a cable for the customer so they can order a spare, and I've found that the old connector configuration means that I used Breakpoint 2. This isn't counter intuitive if BP1=Axis 1, BP2=Axis 2, etc.
The problem is that I cannot find documentation anywhere that specifically defines this.
Furthermore, in the code (over 5 years since I've looked at it) the only BP configuration seems to be the Axis number, which then points to the Axis1=BP1, Axis2=BP2 etc. But I'd love to find where this is explicitly defined for my peace of mind.
Anyone?

Labview based Velocity control linear translation stage XPS Q8
Hello all!
I am currently trying to setup a labview based automation for an XPS Q8 motion control, as a part of a project. What I used to do earlier was logged in to the browser based control for XPS and initialized the linear stage setting the velocity via the browser itself, and then used the VIs for controlling my motion. I required only single axis linear stage motion, and the absolute motion, relative motion VIs
Now, I am trying to automate it all using LabVIEW starting from login to linear stage motion.
I have been successful in all the steps except in controlling the velocity of linear stage motion.
I am unable to obtain any VI 'exclusively' for velocity control. I have been trying to work around this with using VIs that have a cluster of setting various functionalities one of which is velocity. I set velocity to my desired value leaving the other values zero, but the VI's get executed only till the GroupHomeSearch and then error is displayed and the program stops.
It would be highly helpful if anyone can please help me find a way to control the velocity with LabVIEW.
I have attached the images of the related VIs.
Thanks

How do I control multiple motors using Elmo Gold drives through EtherCAT with cRIO 9039?
Hi,
I need to control multiple motors using Elmo drives through EtherCAT, the master is cRIO 9039, and now I can control the motor directly connected to cRIO 9039 by net cable(e.g. Address 0 in the first figure). But with the same procedure, the second and subsequent motors can't be controlled. The control method are just shown as the second figure. Does there any additional steps to drive multiple motors?
Thanks for your reply.

Controller for NI MID-7604?
I have been assigned by PI to run stepper motors on 3 axis and i have been given the NI MID-7604 stepper motor drive. While I am able to figure out how the encoders work for the most part, I don't know what type of motion controller I need for the drive. I read that it is recommended to use a PXI-7350, or maybe PXI-7334, but I am not certain of it.
I still am not sure exactly what my PI wants to use the axis for just yet, but all I know is that they wish for me to attempt to get the motors working and the axis moving.
Or is it possible to use the stepper motor drive without using a motion controller?

Interval for contour move
Hi
I am trying to code a program to let a single axis run a sinusoidal profile. I used the example "Axis continuous contour move.VI" as my starting point. In the example, there is a "signal generator" VI to generate the profile, where the frequency is used as input. Meanwhile, for the "update point" property, the interval is set. So here comes to my question: The frequency seems double-defined.
In fact, I remove the frequency input for the "signal generator" VI and keep the interval alone. It is running but the frequency is not right. For example, I have a 200 point table and set interval as 1, the full cycle did not take 200s to finish. Meanwhile, if I put any number smaller than 1, the motor does not move.
I was so confused by the definition of interval now. Can somebody help?

When I implemented the example there are some errors like Figure(1), and my LabView version is 2018 64-bit . I am not sure whether the dll file is 32-bit? Do I need to recompile the file?

For my project, I need to control 2 motors with MID-7604/7602. But I dont have PCI motion controller.
And I am interested, its possible control MID-7604/7602 without Motion controller,but using Analog I/O?

SMD-7516 Reading the Analog Inputs
Hi all,
We have a project in which we would like to make use of the SMD-7615 card and readout the Encoder position as well as the Analog Inputs it has available, as stated in the datasheet. However, it seems that although they are listed in the manual, no mention to their configuration is made other than "reserved for future use" as seen here on page 15.
My question is: does anyone have experience with this, and is it really possible to just readout the analog signal at runtime via the softmotion API?
Thanks and have a great day,
Cris

MID-7604/7602 Its possible to control with third party motion controller?
I'm trying to find PCI motion controllers to connect to my MID 7604 power drive. I have been assigned to run 3 axes and the only thing I was given to work the motors is just the MID 7604.
I was wondering if it is possible to use a third party motion controller (using the correct application [tho preferrably Labview]) to connect it to the MID 7604 to run the axes.
If not possible, which motion controllers would work best for the project that I have been assigned?
note: I still don't know what the axis is going to be used for, I just want to get the motors to work for now so we can determine what to use it for later.
