title:fault detection in pen. i am doing a project in image processing using labview .i want to interface stepper motor with labview using daq how can i interface and which type of stepper motor is suitable for rolling metal sheet in which the pen is placed at the top

As far as I know there isn't any stepper motor that is directly controllabe by any DAQ. They require, among other things, far to much current, so you would need a motor driver as well. A motor driver is very possible to control with a DAQ.
You could make your own, or use some of NI motor drivers and interfaces: Clicky

No one can (should) suggest a motor to you based on the information given.
However, they way in which they interface to LabVIEW is valid. I've used USB, RS232, and 4-20mA outputs to motor controllers. LabVIEW easily accomodates these in/outs.
Then there's the NI stuff that the other response provided.

I would start with the motor and work down, Labview will woek with any.
1. Figure out how much motor you need: torque, speed, resolution, size (nema 23, 34 .....)
2. Select a drive for your motor: many diferent drivers to control a particular motor, How much current is required, motor voltage, inductance
3. Determine the interface to the controller: step and direction, cw/ccw, serial. (I like step and direction)
4. Determine support options for the motor, encoders, limit switches ...
5. Now you can select your ni card to match the interface, (NI Motion- good for copmlex interfaces and multimotor synchronization, Digital/ counter timers simple but limited conmplexity, less expensive but more software needs to be written)
This all depends on budget and requirements.
