Encoder required?

[blglaw]

I am looking to make a measurement system that will use a quadrature encoder to measure my material and then shut off a motor that is currently controlled by a manual variable DC speed control.  Will the DL-05 work for this or do i need other equipment, like a zip transorb, H0-CTRIO, etc.?  I am looking the use a C-more Micro-Graphic panel to input a length and then have the motor start and measure out the specified length and then stop so i can cut the material.  Are there any sample programs available that do something like this?  I just don't want to re-invent the wheel if it is already done.  Thanks for your help.

Yes an encoder will have to be used.

I'm going to be in the same boat with you soon. my next project after the water one will be using a C-more micro, and a cut to leight run. If your going to use an 05 unit there is a section in the 05 manual already done for something like that, of course you'll have to modify it. Chapter 3 page 6 starts it mode 10. You can go to the site and download the manual and see how they have done it, if haven't already.
Hope this works for you,
Vern.

Cool....i looked at this.  Thanks.  Saves me a little work.  I think i may use the DL06 becuase it has the 24DC supply built in that i can use to power the encoder.  My next chanllenge is finding a controller to interface with my existing Dayton motor. http://www.grainger.com/Grainger/items/2H563

Thanks again.

Bill,
After I looked at what I was doing, I remembered that the mockup program that I'm using right now does not have an encoder. I'm using a rotor flow sensor. All it is, is a reed switch that rotates and picks up the field and makes/ brakes. But yeah I have to use a power supply for the 24VDC, you might get away with using a AC voltage proximity switch on a sprocket to make your counts, then the DC supply can be left out. We used this method for some machines years ago to load product in a pan and other things, it worked pretty good. There is a hundred ways to do this and the more I think about the deeper I get into it, I better stop. Experiment and see what comes out.
