I want to generate/simulate a quadrature rotary encoder signal with 100 pulses/rotation rotating at 6 rpm and using the signal i want to extract postion and velocity information.

 

kindly help me

i am beginner in labview programming

Hi SSG,

 

and what is your problem? (All you gave so far is the description of your homework…)

 

i am beginner in labview programming

You're lucky!

Right in the header of the LabVIEW board you will find links to several training resources to learn LabVIEW!

Best regards,
GerdW

First, there is no reason to type in all caps unless you have a good reason to "Shout" 

 

Now looking at your block diagram

I can offer the following suggestions:

  1. Add Functions and structures to your block diagram that would generate output arrays or waveforms that match what a rotary encoded signal looks like
  2. wire the inputs and outputs of those functions from your controls to what you added to the block diagram and back to your indicators.

There are getting started guides.  Have you looked at them?

STOP SHOUTING!

He attached the whole vi in the same LabVIEW version you are using

Perhaps the two of you could meet at the Library and compare class notes. That would help you both get this homework in on time.

My assignment is to generate or simulate a quadrature rotary encoder signal with 100 pulses/rotation rotating at 6 rpm and acquire the signals generated in above to extract position and velocity information.

 

 

I simulated quadrature rotary encoder.

can someone help me with extracting position and velocity information.

 

i am attaching my assignment here.

Hi SSG,

 

to extract velocity from an encoder signal you need to count the pulses per amount of time.

To extract the position you need to count the pulses, starting with a known "Zero" position pulse…

 

I suggest to read a manual for any kind of industrial encoder (of type ABZ) to learn about all that!

Best regards,
GerdW
