Controling bipolar stepper motors with usb NI-6008 DAC

hi i need help to get an example vi that explaining how to control two bipolar stepper motors using USB NI-Data acquisition card 6008, i have the drivers of the motors, could any body help me?
Solved!
Go to Solution.

you are more than welcome .. ok i attached a vi that could help you .. i'll illustrate how to connect your driver to your usb data acquisition card.
1-on the digital I/P O/P side of the DAQ there's a 5V pin, connect it to the both 5V pins (Pulse and Direction) of the driver.
2- the other 2 pins (Pul- and Dir-) connect it to port0/line0 for Pul- , and port0/ line1 for Dir-. ( you can configure the ports as u like from the block diagram window of the vi ).
3- let the enable pins without connection. ( it's normally enabled).
for motor connection: (dont connect any of these pins to the DAQ)
there are 6 pins.
first you need to know the wires of the motor coils, you could test it with any AVO meter.
1- the first pin connected to the ground of the battery.
2- the second pin to the positive pole of the battery.
3,4 the first coil.
5,6 the second coil.
try it and i hope i helped you, tell me if it worked.

Control two stepper motors with PCI 7332 for sinusoidal movements

Hello,
I am now using two stepper motors of RK566BAE (Oriental motor). I connected those two motors with UMI-7764 and PCI-7332. I designed to have independent sinusoidal movement of each motor. The first motor is wired to Axis 1 and the second to Axis 2 (of UMI-7764).
I want to use Ni-Motion to create a single VI in LabVIEW which helps to control both motors. But I have not figured-out how to obtain the movement I desired.
Could you please advise me.
Thank you so much.

There are two ways to do elliptical arc moves:
Use contouring two download target position arrays to the onboard buffer
Use arc moves in combination with gearing (shipping example). This requires three axes.
The 7332 doesn't support contouring and gearing and it doesn't provide a third axis, so there is no way to use this board for this type of moves. The cheapest NI board that supports elliptical moves in contouring mode is the PCI-7342. As the second option requires three axes, at least a PCI-7344 is required for this method.
Here is a link to a feature comparison table for all NI 73xx motion control devices.

What's the type of control for stepper motor?

Hi,
I'm using PXI-7358 controller, UMI-7774, Industrial Device NextStep third part microstepping drive, stepper motor SANYO-DENKI (type 103-8932-6421, NEMA42) and incremental encoder 3600 ppr (14400 count/round). I want to say what's the NI onboard type of control used to control motor step position? In the case of servomotor the type of onboard control is a PID, in the case of stepper motor what's the type of control? What's the MAX parameters to set for the project specific (overshoot, settling time, rise time etc..)? What does it means "Pull-in Window" e "Pull-in Tries" in MAX? So, it's possible control the stepper motor with user's algorithm control, excluding the onboard control?
Thanks for your patience,
Best regards

Using LabView, Arduino, and Easy-Driver to control a Stepper Motor

Hello fair folks of the LabView forums!
I am a humble engineering student in need of some advice and input on a project I am working on.
I’ve also done a fair amount of reading on the LabView forums with people trying to use LabView and Arduino to control stepper motors, and I’ve used as much information from each as I could. However the problem I'm encountering now is one which is unique to my VI Configuration.
So, here is what has been done thus far:
-Installed LabView Interface for Arduino [LIFA]
-Installed necessary VISA drivers for LabView to communicate with arduino
-Uploaded firmware to Arduino to allow it to communicate with LabView
-Properly wired Stepper Motor with Easy Driver and Power Supply; I have verified this by first using the Arduino independently of LabView, using example code found here.
-I have created a VI, and have just recently got it to run without reporting back any errors. While I suspect the behavior I’m encountering has to do with something inside the VI, it is difficult to determine as there are no errors being reported!
But here is general problem I am encountering:
-Connect Joystick to USB Port, connect Arduino to USB Port.
-Plug in outlet for Power Supply
-Open LabView VI
-Run LabView VI
-LabView successfully detects Joystick, and Arduino.
-Tilt Joystick; Stepper Motor moves in proper direction, but it only takes a single step. If held, it does not move further. If returned to zero, and then tilted, it again only takes a single step.
I know that in the example code, the Arduino issued the step command by writing the signal from LOW to HIGH, and varied the speed by how often it did this.
I assumed that the Write-PWM feature would do this same thing, but perhaps my assumption is wrong. I will continue to tinker with this myself, but I would be extremely grateful for any insight you might be able to lend.
I’m thinking, if not the Arduino Write-PMW feature perhaps a simple timing-sequence that could be used to alternate between writing 0 and 1, with the timescale of the sequence being scaled to the X-Axis from the Joystick. But, I am open to suggestions, and certainly appreciate any thoughts you may have to offer!
Attached to this is the VI used in this setup, a picture of said VI, as well as a rough sketch of the hardware configuration.
Thank you!

Configure stepper motor with MAX

Hi,
After wiring VI, I don't know what must I do to control my stepper motor?
Can anyone give general information what must to do.
How to configure stepper motor with MAX? I'm using PCI6036E.
Thank you

The answer to your question is dependent on your motor/motor controller and the inputs that it needs. Are you using a stepper motor controller? The PCI-6036E probably won't be able to supply enough current to power your motor (max 5mA) by itself, so you will probably need a stepper motor controller. With the 6036E, you do have 2 analog outputs, 8 digital I/O, and 2 counters (can be used for pulse train generation). Have you considered an NI Motion Control Board? ni.com/motion

How can I control 3 stepper motors w/ amplifier by sending TTL pulses from DIO96

We have NI PCI-DIO-96 board and we have 3 stepper motors with amplifier and encoders. We want to control the motors by sending TTL pulses directly from the DIO-96 board to the amplifiers. Is this possible? What would you recommend if this is not a good approach? Thanks in advance.
Roman Zeylikovich

Roman,
Thank you for contacting National Instruments. While using a motion controller would be the recommended approach for any type of motion application, you may be able to use your DIO board to generate a TTL pulse train to control the step and direction inputs of your drive and motor. You will need to make sure that the current sinking and sourcing specification for the DIO-96 fits your stepper motor. That board is not designed to source very much current at all so this is one issue you will need to verify. Also, this board does not have any counter/timer logic that can handle quadrature encoder inputs.
Again, this digital device is probably not the best solution to control a stepper motor, but, depending on your hardware, could be configured to work proper
ly. The PCI-7334 is a low-cost stepper motion controller that can control up to 4 axes and is designed to easily accommodate these types of applications. You can browse through more information on our Motion controller boards at the following website:

Possible to drive a stepper motor with PCI-6111?

Is it possible to drive a stepper motor with PCI-6111?

Hello Tristan,
If your stepper motor is TTL compatible you should be able to control it with one of the two counters on the board. Keep in mind that the stepper will ask for a certain amount of power so before attaching it track down how much power it consumes and take a look at the Specifications of the PCI-6111 to be sure that the counters on the board can deliver that amount. If the stepper takes to much power you have to use some kind of power drive which can be controlled with digital (TTL) signals or Analog signals between -10V and +10V.
Hope this helps.

How can I control 3 stepper motor in same time?

I want to control 3 stepper motor and 30 electro-valves.
I only had a few lessons on how to control one in C in college.
Now I need to do this in labview and using an board from NI
How can do the control of the three motors in same time?
What the best board to do this. Maybe the NI PCI 6034.
But I will need more than one?

At least some of the NI motor controller boards have up to 32 digital lines which can be set to input or output. I did not write the software for our systems but we are using quite a few of the digital lines for our systems and have no problems reading the digital inputs or setting the digital outputs. Also, the digital outputs offer a high current sink capability and usually can be used to drive external drives without any interface circuits.
The digital lines are available on a separate connector of the NI boards and there are also break-out boxes (with screw terminals) available. I do not see any serious problems to do your control tasks just with one NI motion controller board, as long as you do not have any special requirements (high sampling speed, high frequency pulse output etc) for the digital lines.

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 can I output a square wave to control a stepper motor using 7332 controller?

I have the following system configuration for testing a linear actuator (LA):
LabView 7.1
NI FlexMotion 7332 Motion Controller
NI Flex DMM 4070
The LA is a stepper motor with Step and Direction of Rotation inputs, as well as some discrete I/O for Power Enable and other functions.
The LA specification only requires that I send a 50% Duty Cycle square wave signal with frequency less than 300 Hz to it in order to make it step. The LA has it's own power source. I only need the 7332 to generate the drive signal and the DOR signal to the LA. Using some of the example VI's, I can get the LA to work, but I will need to incorporate the functions in to a custom application.
How can I weed through the numerous advanced functions the 7332 offers and only generate a DOR signal and a step command at a user-defined frequency. How do I set up the controller for this?
Thanks

Hello,
All the VIs that you can use to create a pulse train and digital I/O from your motion controller are found in the "Analog & Digital I/O VIs" sub-palette in the "Flex Motion" palette. Use "Load PWM Duty Cycle" and "Configure PWM Output" VIs to create the square wave. Use the "Set I/O Port Direction", "Set I/O Port MOMO", and "Set I/O Port Polarity" VIs to create digital output. I hope you find this information useful. You can learn about the specifics of these VIs and their inputs/outputs in the NI-Motion VI Help.

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.

Stepper Motor with Linear Stage (Position Control and Data Acquisition)

Hey All,
So.. I've attached a stepper motor to a linear stage and so far it's working pretty well. Using a stepper motor driver from Pololu, I've simplified the control of the motor by just using output pulses from the counter output of a PXI-6143. I've tested the motor using the Pulse Train examples in LabVIEW and all is working well.
My goal now is to allow the user to collect data from a pressure sensor, attached to the linear stage, every X number of steps. From what I can tell so far, and please correct me if I'm wrong, the motor step movement is synchronised with the pulse train input. That is to say, if I give the motor a 200 step pulse train, the pulse train ouput is completed at the exact time the motor has moved 200 steps. From this, I've created a VI that moves the motor X steps, aquires the data point, and then repeats this process for the required amount of data points. The problem with this is that the motor movement is not continuous; it stops for a split second to take the data point.
How can I have labview ouput a pulse train of say 1000 steps and record a data point every 50 steps?
Two ideas that came to mind were:
1. Use the counter input port on the card to count the pulses being sent to the motor.
2. Use an encoder connected to the motor shaft.
I wanted to stay away from theses ideas though since they require resources from the DAQ card.
Thanks,
Ryan

Hi Ryan,
Just to cover all the bases, what version of LabVIEW are you using and can you attach your VI? Initially your ideas sound like they should work, do you expect to be nearly maxing out the DAQ?
Thank you,

How do you controlling a stepper motor

I want to control a stepper that is lifting a scissors lift but I want to calibrate it to different height enter in the heights into memory and then recall when necessary.

Not sure if you were looking for electrical help or programming help. If you want more details you could reply to the thread....
You need a stepper motor controller. This is an electronic circuit. They can probably be found with a web search. The range in prices from $50 to $1000 or more. Or you can build one using componants from National Semiconductor or Allegro or Texas Instruments or other chip makers.
Depending on motor configuration, you can have a unipolar (6 wires, 3 wires per phase) or bipolar system (4 wires, 2 wires per phase). If you don't have instructions with your motor, you can figure out phasing with an ohmmeter.
Usually the controller has a square-wave input and a direction input. Sometimes some other inputs. Usually there is one step (or even one microstep, depending on the controller) per rising edge. Sometimes they have an analog speed input, but this kind of controller is probably not right for your application.
You can count steps in one direction. The stepper controller takes care of powering the windings to make the motor turn round. Then count steps back. Unless you have stalled the motor, the motor steps are very repeatable in location. If you remember how many steps from some reference point (i.e. all the way in one direction, say), you can save the position reference and come back to the location by counting up or down until your current position reference matched your saved reference.
Hope this helps some.

Elliptical Motion of Two Stepper Motors with PCI 7332

Greetings,
I am trying to move two stepper motors on a 2d elliptical arc using LabView and PCI 7332 controller board. The 2D ellipse example in the LabView library does not work with the 7330 series. Is there any other easy way to perform such a motion with PCI 7332? Thank you in advance.

There are two ways to do elliptical arc moves:
Use contouring two download target position arrays to the onboard buffer
Use arc moves in combination with gearing (shipping example). This requires three axes.
The 7332 doesn't support contouring and gearing and it doesn't provide a third axis, so there is no way to use this board for this type of moves. The cheapest NI board that supports elliptical moves in contouring mode is the PCI-7342. As the second option requires three axes, at least a PCI-7344 is required for this method.
