Measure frequency of Z pulse of an accu coder shaft encoder to measure speed using an 6034 E card

[vickey4036]

Hi,

I would like to measure the speed of a engine which has an accu coder encoder hooked onto it. It provides 3 pulses A, B, and Z. I am using a 6034 E PXI card. I wanted to know if there are any examples/ideas that could help me with this (I am new to the digital programming in Labview). I have moved to NI Daqmx 9.8 recently from the older version which supported legacy codes and hence in process of updating the code. I also want to know if an external clock source is required to do this. this.

Hello,

There are several examples in the NI Example finder (you can get here by going to Help >> Find Examples in a LabVIEW window). You can browse to the encoder examples by going to Hardware Input and Output >> DAQmx >> Counter Input. You should be able to find a few examples that will be helpful. 

Also, this link is a good resources for getting started using DAQmx: http://www.ni.com/white-paper/5438/en

Thanks!
