Hi SHV,
actually I don't know in which context you want to use your existing hardware for your stepper motor.
1. The hardware, which you describe, is/was used for which application? ( data acquisition, controlling a system, etc)?
2. Did you buy the hardware especially for the motor application?
3. You don't know how which signals are required for your stepper motor.
Here are some basics from NI about motor control
Fundamentals of Motion Control
http://www.ni.com/white-paper/3367/en
NI Motion Control Technical Library
http://www.ni.com/white-paper/3054/en
4. Why do you get the idea the digital output module 9474 is suitable for the stepper motor?
I would recommend to talk directly to the customer support, so we can figure out in detail your aims about
the application. Contact your local NI office or request
a service request on following website:

How to run a stepper motor for an amount of time determined by a feedback?

Hi,
I'm using labview 8.6 and I'm trying to use a ORIEL sterppermike with a 20025 controller.
I have implemented a VI that has a stack of commands in a for loop. Every loop has the following sequence of commands:
command 1) start the stepper
command 2) wait for feedback to reach a certain number
command 3) stop the stepper
command 4) wait a certain time before starting again
To start the stepper I use a subvi from the example folder:
C:\Program Files\National Instruments\LabVIEW 8.6\examples\DAQmx\Counter\generate pulse.llb
--> Gen Dig Pulse Train-Continuous.vi
I don't understand why the sequence get stuck at command 1 and never gets to command 2.
I attach the vi for completeness.
Thanks to anyone that will help,
Matteo

Hi, I'm not sure whether this is the right place for asking this question or not and if not, then please guide me to the right place for asking such question. Thanks.
I have a stepper motor with the Vector Network Analyzer Anritsu MS4623B. I got it up and running with the LabWindows/CVI. I need to sync the motion of the stepper motor with my data acquisition. Basically, I have to acquire the data in a way that in the start the motor will come back to home position wherever it was and then I want to move it to the specific position to do the measurements (For Example, I want to measure the 40 GHz channel between 1m to 3m movement of a stepper motor on a linear positioning system (ball-screw)). I've interfaced the VNA with the PC using LabWindows/CVI and I've controlled the clockwise and anti-clockwise movements of the stepper motor using LabWindows/CVI but I'm unable to sync the system in a way that whenever I run the code, the motor will run back to the home position and then move to a specific measurement start position and move till the end position and in between do the increment and stop and acquire the data. Is there any one to help me please? It's really urgent please and I'm doing this thing first time so please guide me in a proper way. I shall really apprecaite that and will be highly obliged with you. Thanks for your time and concern.
Thanks and Regards.

To drive Unipolar Stepper Motors using MID drive

Hello friends I have purchased a RS components MID drive and I want to control a unipolar stepper motor using the same. The stepper motor is having 6 wires. I have used the same drive to run a bipolar stepper motor but I need to know as to how I can wire a unipolar motor to the same.I would like to know the connections and the disadvantages if any in driving a unipolar stepper motor using the MID drive.

You can drive unipolar motors with the 7602/7604, but you wire them as if they were bi-polar. The user manual (which can be downloaded from the NI web site for free) shows the way to wire the 4-phase motor as a two phase motor on page 26. The basic idea is that you either ignore the center tap - wire Phase A to Phase A, and Phase A' to Phase A', or ignore one of the phases by attaching Phase A to Phase A, and Phase A' to the center tap.
Hope this helps-

How can i control the motor movement of stepper motor using a NI PXI 7330

Good day to all,
i'm a newbie in programming in motion control of NI. I just want to ask if how can i control the clockwise and counter-clockwise rotation of a stepper motor using NI PXI 7330 module. all i can do is the counter-clockwise rotation using the example vi (Simple one-axis move.vi) found in the examples of LabView 2009.
Thanks

what type of limit switch sensor are you using and how did you wire itß What are your MAX settings regarding the limit switches?
Good day SIr Jochen,
I am using two reed switch for the reverse and forward limit. I wired the signal wire of the reed switch to the limit ports(forward and reverse Limit) and its ground to the digital ground of the UMI-7764.

Robotics-Running two stepper motors

Hi
I am working with LIFA (labview interface for arduino) to run two stepper motors to create a special (simple) path on XY plane. The example code (Arduino Stepper Motor.vi) works fine with one motor, but I don't know how I can modify it so that two motors can move with one time pushing the button, one after another while taking turns. Any Ideas?
The motion plan is as follows: 1. Motor 2 is stationary and motor 1 moves the load for 100 steps in X direction, then it stops and motor 2 starts to move the load for 70 steps in Y direction.
2. The same as 1, only the direction of motor 1 motion is reversed, and motor 2 moves 85 steps instead of 70 in the same direction.
3. Repetition of 1 and 2 for 4 times with different number of steps at each level.
I have twe big easy drivers, and one Arduino Uno.
I truly appreciate your help,
Best,
Ashkan

You could create a state machine.
You could create a movement recipe where you enter in each sequential movement, and the code steps through the recipe one movement at a time.
You could create some combination of 1 and 2.
How do you want it to work? Are these steps going to remain constant, or do you want to be able to change them from one run to the next? How much do you know about LV? Have you any code that you wrote? What is the long term goal -- are you building towards something specific or just learning for the sake of learning?

Sinusoidal velocity profile of a stepper motor using labview

Hi I am trying to get sinusoidal velocity profile of the stepper motor using labview.
Could anyone please help me out...

I'm also really interested in this solution.
I think you could do it by controlling the velocity of the stepper with points (excel) or function maybe... but that's an idea...

Stepper motor and NI6025E card

I want to control a stepper motor with a 6025E National instrument card. My stepper motor is controlled with a microstep controller.
Does anybody have already done that ? I am interested by some examples...
Please HELP me...

I don't have any examples but I have done this before and it's not that difficult in principle. Getting precise timing can be tricky, and you'll have to use counters rather than the regular DIO ports for that kind of precision.
I had an MC3479 stepper motor driver to control each motor (there were 2). The way I did it was to use a counter for the clock signal and the DIO ports for control. I generated a gated pulse train on one of the counters, with a DIO pin (DIO 0)as the gate. The Direction, Full/Half step, and other control lines were also connected to the DIO port. I just wrote out whatever data word I needed to setup the motion I wanted, with the pin 0 high to let the clock move the motor. The motor had to be stopped by clearing bit 0, which I had after a tim
ing delay that was changed in the program. It required a little calculation to get the time delay matched with the frequency of the pulse train to get the number of steps I needed, and it was only approximate; I wasn't worried about exact position as much as being able to adjust the position dynamically.
For precise position you might try using just a digital line to increment the clock. This is simplest, but the timing will depend on your program. You can also use the other counter for a very precise gate signal, which gives accuracy as well as time-specific rotation, but uses the other counter and is programmatically more complex.

The TIme Machine volume does not have that checkbox.
I think the issue is with your Finder...
Go to Finder "Go" menu hold the option key and choose Library. Then go to Preferences trash these files:
com.apple.finder.plist
com.apple.sidebarlists.plist
Then, restart, or log out and in again.
(You will have to reset a few finder prefs the way you like them.)

Running 2 stepper motors with LabVIEW using RMV ST400-NT controller and driver

Hello, I am new to programming as well as motors in general so please bare with me in my attempt to explain myself. I have a project involving laser therapy and I am attempting to control two stepper motors from Falhauber, Type AM2224-R3-AV-4.8. I will be using a RMV ST400-NT controller and driver. Original plan was to use 3 stepper motors for control in 3 axis but realized 2 axis is complicated enough. My power source is an Agilent E3630A. I am new to this whole thing and from what I have read form examples and other posts is that NI drivers seem to work best for these applications. I've written simple programs from examples, reading and watching videos. I want to know whether it's possible for these to work together using LabVIEW and also a nudge to help me get started would be much appreciated. Can someone please help guide me in the right direction, I feel a bit lost when it comes to all this. Thank you for your time and consideration. Also, I will be using Windows 8 laptop with Labview 8.5. I have attached pics of components I will be using.

Hi jtarula,
I want to preface this response by saying that I am mre familiar with NI controller and driver rather than the one that you have. I am assuming that you are using the dll provided by the manufacturer here:
http://www.rmv.com/download.htm
With these, you should be able to interface with LabVIEW using the call library function node. What the controller is capable I am uncertain of. I am certain that you should be able to since another user has commented on the use in LabVIEW before in another forum post.
I also want to let you know that LabVIEW 8.5 is not supported on Windows 8, which means that you may run into some compatibility issues. Here is the compatibility chart.

How do I establish serial communication using LabView to two stepper motors using a motor controller?

I currently use an off the shelf motor controller to run my two stepper motors. It already has integrated a firmware software that sends commands to operate each motor. I would like to create an interface where I can send these commands using LabView. If someone can point me in the right direction I would appreciate it.

Look at the examples for the serial VISA vi. Something like Basic serial write and read.vi is a good starting point.
Have you searched for a LabVIEW driver at the NI LV driver network? Asked the vendor?
If you write your own driver with the serial VISA vis remember to open and configure the port only once at the beginning and close it at the end of your program.

Controling four bipolar stepper motors using one DAQ

hi all
l've just started using labview an i am looking to contorl Four bipolar motor for a spine robot though four stepper motor driver using a NI USB-6211 DAQ each motor will be independent so i am wondering can this this be done with one Daq since there is only two counter outputs on the digtal and the same on the analog.the speed of the motor does not matter as they will be push and pull.

Hi polarmess,
Welcome to the NI Discussion Forums and LabVIEW. The USB-6211 has (among other functions) 4 digital outputs and 2 counters. If the digital outputs are not sufficient for your application (e.g. not quick enough) and you also want to control each of the 4 motors individually, then then USB-6211 would not be suitable for this application.
The NI sales team are always available to provide advise on hardware for specific applications, and I encourage you to call in to your local NI branch to discuss what the most appropriate hardware would be to control your robot. Our contact details are available via the contact link on ni.com.
