Is it possible to do motion control using Lookout

Is it possible to use activeX controls in Lookout for controlling nuDrive motor drive?

Hi,
This doesn't directly answer your question.. but will hopefully give you some ideas to explore. It's more of me thinking aloud..
Are you familiar with NI's Datalogging and Supervisory Control (DSC) module for LabVIEW? This is an excellent solution for projects involving both, a high number of IO points in an industrial setting and for high-speed measurement and acquisition. You have the benefits of LabVIEW, like DAQ, Motion and Vision, and at the same time have the Supervisory Control features like alarms, historical logging, security, networking, etc., that you want from Lookout. You can get more info' on DSC from:
http://sine.ni.com/apps/we/nioc.vp?cid=10418〈=US
I strongly recommend you take a look into this as a solution if your project i
nvolves Motion along with high number of IO points.
However, if you HAVE TO use Lookout, another approach would be to use DSC in combination with Lookout. Let the DSC module address Motion issues, and it (DSC) being an OPC Server, can be in turn communicated with Lookout (as an OPC Client).
Hope this helps,
Regards,
Khalid

Is it possible to do torque control using Flex Motion?

I am trying to control the output torque to a motor?
I know you can do velocity control using FlexMotion, how about torque control?

To hold a servo motor at constant torque, all you need to do is provide a constant voltage. You can accomplish this using the analog output (DAC) of a FlexMotion board. To gain access to the DAC, configure the axis as an open loop stepper, then use the Load DAC.flx VI to output an analog voltage. The downside to this is that you won't have feedback, so you'll have no way to determine your position.

Motion control using MCU 28stage controller of Zeiss

Hi,
Does any one know how to control Z axis motion using MCu 28 stage controller of Zeiss, with/without LabVIEW. I am working in the windows environment. Any suggestions will be appreciated.
Thanks
Deepak

Hello Deepak,
The MCu 28 stage controller by Zeiss should have a driver that will control it. The driver will be developed and managed by Zeiss.
- If the driver is a .dll that you can make function calls to, then LabVIEW has the ability to make calls to the .dll.
- A .dll can be accessed by most programming environments (C, C++, Visual Basic... & LabVIEW).
If you do not have access to the driver for the controller, then you will need to follow up with Zeiss.
If you are wanting a significantly easier motion controller to integrate into your application, National Instruments offers a variety of Motion Controllers (www.ni.com/motion).
- If you have any specific questions regarding upgrading or making .dll calls from LabVIEW, then please contact National Instruments
at 1800 IEEE 488.

Homing switch causing motion control problems

I am controlling a dome for a telescope. I have a home position switch and motion control using one of NI's motion controllers. Everything works fine except for one bug. The dome just goes around and around. I can run a Home type reference search and it works fine. But if I command a position that runs through the home switch zone the dome stops moving. If I hit the command a second time it runs right to the correct position.
So why does the home switch stop the motion if I am not doing a reference search. Should I be using some other form of referencing?
Thanks,
Dave
David A. Taylor

Do you have the home switch also configured as a limit switch?
What motion hardware are you using. In addition to home limits, the ni cards often have a + limit and - limit and also a software limit, these can be configured via the api or in max.

Hi Patrick,
The reason why the Motion Control examples will not work for you is beacuse they are meant to be used with the NI Motion boards. Since you are using DAQ boards, the examples are probably not going to be able to help you too much. However, there is one example on the community that might be a place for you to start.

What exactly do you mean by this? What do you want in the case structure or while loop?

Is it possible to condition a load cell signal with a 1520 SCXI and then use it as the primary analog feedback for a 735X motion control board?

My system
PXI 1052 chassis
PXI 8196 RT controller
Flexmotion 7356 motion controller
Flexmotion 7354 motion controller
6259 M series DAQ
1520 SCXI
1520 SCXI
1314 SCXI frount mounting terminal block
DSM strain gage load cells
Exlar SR Brushless PM motors
Kollmorgen servo star CD series 5 drives
My objective:
I want to measure the force on the load cells with the 1520 SCXI (i.e. excite the load cell then amplify and condition its output) then I want to use this analog (force) signal as the primary feedback for my motion control system (7356 and 7354 motion controller connected to my drives and motors).
The problem:
The motion controller boards (7356 and 7354) can be configured for force feedback control via analog feedback from a load cell. However the boards implicitly expect the load cell signal to be amplified and conditioned with and external signal conditioner rather then using an NI SCXI module. Currently I’m am reading the SCXI signals via the 6259 M seriers DAQ and consequentially have no way to route the signal into the 735X boards for force feedback control. I can use softmotion to control the motors but then I loose the fast PID update rates possible with the 735X boards.
The question:
Is it possible to condition a load cell signal with a 1520 SCXI and then use it as the primary analog feedback for a 735X motion control board?

Hi GG,
Thank you for your feedback.
>create your own external circuitry to amplify the signal.>
True a few op-amps could amplify and filter the signal externally but the performance of such an amateur built system will never match the accuracy and functionality of the 1520 SCXI. That’s why we spent the $2500 for the professional version.
>One thing that you could do is to use a UMI with your motion controller and then wire your signal from your SCXI to the UMI.>
As I understand it the UMI is basically a break out connectivity interface for third party drives. After conditioning and amplifying the analog force signal with the SCXI module the analog signal isn’t available to wire into a UMI. To my knowledge the conditioned signal of the SCXI resides only in the PXI backplane (i.e. there is no physical access to the conditioned analog signal). Can you explain how the UMI could be help here.
Again thanks for your input GG.

Is it possible to generate a motion control vi from parameters entered into MAX?

In the process of familiarizing myself with LV, It was brought to my attention that it might be possible to generate a VI from parameters entered into MAX. Is this possible?
Right now, I am getting familiar with motion control and LV by using MAX's 1D and 2D motion controller interactive environment. I was wondering if there was a way for LV to take the parameters and selections I have made in the various fields and make a VI from it?
I have tried searching MAX's help, Google searching, etc. but have not found anything.......
Thanks

In LabVIEW you can use "Initialize Controller.flx" to load the configuration settings from MAX to the motion control board. There is no way to create vis from the Interactive window, but if you are looking for such a feature, you may want to look into the NI Motion Assistant.
NI Motion Assistant is an interactive environment for prototyping your motion control application without programming. Later you can export your motion sequence to LabVIEW.
If you want to test Motion Assistant, you can download an evaluation version here.

Has any one used elmo motion control products

Hi
I am using a elmo motion control servo node.This has a rs232 interface. I want to know whether it is possible to use this node with lanview.

We have used elmo drives for brushed servo motors several times in th past without problems. What is the model of the drive you have?

How can I use flex motion control VI without hardware?

I would like to try and simulate the motion control of my system before i hook up the motion control card. But when I use the VI in flex motion contro took kit it asks for address or something and gives me an error. Can't I just simulate without hardware?

Hello,
The only way you can use FlexMotion without any hardware is to set it up as Open Loop Stepper Control. Otherwise, you will get errors when no encoder signal is fed back to the controller.
Please let me know if you have any further questions.

Tension control in labview using PCI 7354 Motion Control Board

I want to make a program for web tension control of roll to roll system in labview using PCI 7354 Motion Control Board. Is there any interface program that can convert my controller output in a format to be directly used as the input of PCI 7354 (Motion Controller Board) for tension control?
Thank you!

thanks for your reply, i have already make the code of a straight line move and the motor moves successfully, but know i want to put the H-bridge to be able to make a reverse direction for the motor, for your information i only use a PCI-7340 controller and a UMI-7774, where the controller connected to the UMI-7774, the UMI connected to a PWM circuit and the PWM connected to the DC-motor, so what do you think i can do?

"Distributed motion control'

Hi there,
For a future project we are making a first study, and as I'm not really familiar with NI solutions, I hope some of you can share some thoughts.
For this project, we will have to control the following hardware:
- 28 cryogenic stepper motors in open loop (no encoder feedback possible) and very simple motions ("move x degrees") just a few times per hour max.
- 2 cryogenic stepper motors in open loop, but with a constantly changing position setpoint (>50Hz should be fine)
- 50-100 I/O temperature and pressure readings (sampling in de range of a few Hz maximum)
How would a possible "NI solution" look?
Our systems engineering guidelines say that it is highly preferrably to move the "control unit" away from the instrument (say 50 meters apart, in a computer room), and that all fieldbuses should be ethernet based. In that case I was thinking to have:
- a PXI chassis in the computer room
- an EtherCAT connection from the PXI chassis to a daisy chain of 4 NI-9144 expansion chassis, all equipped with the 28+2 NI 9512 stepper controllers, connected to 28+2 stepper drivers
- an extra NI-9144 (or compactFieldpoint chassis) for the DAQ
It seems quite rediculous to have so many NI-9144 expansion chassis, so another solution is to ignore the "control unit near instrument" rule and to have a single PXI controller with 4 8-axis stepper controller boards and a few DAQ boards inside.
Another solution would be to have 28+2 standalone third-party stepper "controller and drivers" inside the instrument, connected with an ethernet fieldbus to a labview target in the computer room. But I'm having troubles of finding suitable stepper controllers+drivers (maybe because stepper motors and ethernet motion control are not so commonly found in industry?)
Thanks for any thoughts on this,
Wim

We've roughly worked out a layout of such a control system on paper, but it remains a quite vague "study" until the project enters the next stage (which depends on funding since it's a scientific instrument). I can send you a document about it if you want (just PM me your e-mail address), but I doubt it'll be of much use. Anyway the final solution will look much different from our original plan, and if I'd have any say in it, I'd most likely choose a PLC-based solution over this one.

PCI6602 for motion control?

Hi, I am wondering if it is possible to use the pulse generation of the
PCI6602 to control a stepper motor
driver, the problem is that I need aceleration and deceleration in the
pulse train.
I'm using the PCI6602 for event counting (~ MHz), and I need to
synchronize the data acquisition to the stepper motor pulses at a rate
of ~10 KHz. It would be nice to use a single card for both acquisition
and motion control.
thanx,
Stefano

Stefano,
Yes, you could use the PCI-6602 to control a stepper motor. This will require two counters per stepper axis to control the step/dir or CW/CCW lines, or one counter per axis if you only want to move in one direction. You would need to programmatically ramp up the pulse rate to control acceleration. However, since updating the output pulse train frequency is software timed, acceleration may not be very smooth and you risk losing step. Also, you would need to manually handle any pull in moves.
While you could achieve reasonable stepper control with the counter board with some trial and error, the PCI-7334 would probably be a better solution. This controller easily handles acceleration and deceleration and allows you to route the encoder signals over the
RTSI bus to control the data acquisition process.

PCMCIA card for motion control

Hi,
I am trying to control a stepper motor through LABVIEW. After perusing through the site, I know that I would need a stepper motor, a corresponding motion controller and a universal motion interface. The problem I have is that I am trying to control the stepper motor through a laptop (which does not have the Parallel Port slot). I am wondering if a PCMCIA card could work (by providing a parallel port to the laptop) or if it would not meet the necessary requirements to operate the motion control through the universal motion interface.
Thanks

It IS possible to drive an UMI interface with a parallel port providing TTL compatible outputs, basically the UMI interfaces are (advanced) break-out boxes feeding the step and direction pulses to a motor driver and connecting feedback signals (encoders, limit switches etc) back to the PC. But in this case, you would have to write your own routines for accelerating and slowing down, as well as evaluating the feedback signals from an encoder or limit switches. There are several manufactures making motor drivers which can be driven via a serial or USB interface, in case you cannot use a NI controller board it will be much easier to use such a setup since the motor drivers usually incorporate at least a basic motor controller providing a set of commands which makes it much easier to control a motor than with doing everything from scratch.
