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-

  • What is the data throughput in labview. I want to use the parallel as acheap digital i/o to drive a stepper motor.

    I am trying to use the parallel port on a win xp machine to send data a@ up to a 3k rate. This is for the the purpose of driving a stepper motor. I have tried the port.out vi and placed this vi in a loop and it on a scope it looks like I am limited to a a 200hz rate. What am I doing wrong??? Can labview do this or is it too slow ???
    Thanks

    Basically the way the Port I/O VIs are implemented they call through a
    device driver for each port access. This slows down the maximum port
    accesses to something like 1000 times per second depending on the speed
    of your CPU.
    There is a way to do it faster but that is a little more trick
    y. The
    idea is to use a device driver to enable particular port addresses to be
    accessed directly from the application level instead of always going
    through the kernel.
    I have written such a VI library and accompagning DLL and device driver
    and made it available on OpenG. It is not yet part of the standard
    binary distribution packets so you will have to get it from the CVS
    repository.
    Go to:
    http://cvs.sourceforge.net/viewcvs.py/opengtoolkit/portIO/built/portio/
    and download all the files in there including the ones in the
    subdirectory "ogportio.llb" and if you like "docs"
    If you want the nitty gritty technical details you can also look at
    http://cvs.sourceforge.net/viewcvs.py/*checkout*/opengtoolkit/portIO/c_source/Description.htm?rev=1.5
    On my 866 MHz Pentium mobile I can increase the number of port accesses
    in this way from 440 ms for 4000 read byte port accesses (100us ms per
    access) to 20 ms for the same number of read accesses (5 us per access).

  • Can I Connect a 6-wire Unipolar Stepper Motor to the MID-7654/7652?

    I am trying to connect a 6-wire unipolar stepper motor to the MID-7654/7652  motor driver and was wondering how the wiring would work on that?

    The connector is simply a pass-through for the signals generated by the motion controller card for hooking up to a separate driver compatible with stepper motors. It would be used if you had a combination of servo and stepper motors in your system used in conjunction with separate servo and stepper drives.

  • Drive a stepper motor

    Hi,
    I'm using LV 7.1 Pro under Windows XP. I can use a PCI 6602 card and also a PCI MIO 16 XE-10. I must drive a stepper motor via a specific driver : Philips TJA1010. This driver is working with a clock at ~7 Khz used as timebase and it has a serial data input  that will activate the differents driver outputs connected to the stepper motor to create the rotation.
     The sequence order to send via the serial data input is described in the attachment. The problem is to be able to generate this sequence on the serial data input. I already checked on the forum and found the .vi attached but I don't see how to create my sequence.
    Thank you in advance for your help

    Hi pasolo,
    I'm not familiar with the TJA1010, so I'm assuming for this post that you have already hooked up one of the digital lines from your DAQ card to the input on the motor driver.
    From what you describe, it sounds like you want to do a specific pattern generation on an external clock.  There is actually a great example for that in the NI Example Finder.  Just open LabVIEW and go to Help >> Find Examples.  From the Browse tab, go to Hardware Input and Output >> DAQmx >> Digital Generation >> Cont Write Dig Port-Ext Clk.  This should allow you to write a pattern of 0s and 1s that correspond to your required waveform.  Also, some of the other examples in there might be helpful to look at as well.
    I hope this helps!

  • 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.

    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:

  • Whether it is possible to drive a stepper motor from speedy 3's output

    actually i am trying to design an voice controlled wheel chair for my application wat i have did is tat i have writern two programs using labview one is just storing my voice for four commands(namely front ,frontright ,frontleft,stop) ,tat  it stores some value in an array, in my second vi i am speaking one of the four commands, and tat comands amplitude is stroed in an array and i am just comparing it with the values from the first array which i have stored it for all the four commands if any of the array value matches just approximately the i have to make the stepper motor to drive in tat direction i have done it with PIC microcontroller can u give some directions to implement using speedy33

    Hi,
    The SPEEDY-33 Robotics Daugher Module is an add-on device that mounts onto the SPEEDY-33 to provide more functionality. It includes:
    DC Motor Drive Outputs (4)
    Auxiliary Servo Motor Outputs (4)
    Analog Inputs (4)
    External Power Supply Connection
    Details of the daughter module, you cn find at the link below:
    http://digital.ni.com/public.nsf/allkb/832F1F4B12ECE1BE862572D100765898?OpenDocument
    This daughter module is NOT an NI product.
    For connecting a stepper motor, since speedy 33 has digital outputs, it is possible to work a stepper motor. However, you will have to connect a stepper motor drive inorder to amplify the signals to the current specifications that the stepper motor demands. Find out the specs of your motor and choose an appropriate drive.

  • I look for a vi which allows to drive a stepper motor drive

    The stepper motor is: HIGH-RESOLUTION ROTATION STAGES of Newport

    What type of stages do you have? Are they the SR50 series? If so what type of controller do you have? I have VI's for the ESP6000 PC-Based High-Performance Motion Controller (From the Newport Website) that work really well. But these won't work if you don't have the same controller. Do a search on the Newport website for your controller. They will have some VIs and utilities for your specific controller. Here is the link that will show the compatible controllers for the SR50 Series
    Compact High-Resolution Rotation Stages.

  • 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.

  • How do I establish serial communicat​ion 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.
