How to get data from a model of an horizontal crane

Hi! I am a beginner in arduino, I would like to know how to get data form a model of an horizontal crane.

I have a card which converts the digital data from the encoder to analog data, and I have to use arduino
to extract data such as frecuency or velocity and show them in Labview.
Thank you very much

I have no idea what you mean by a "horizontal crane". I thought cranes are mostly vertical?

And I have no idea where frequency or velocity come from.

What do you mean by a "card which converts the digital data from the encoder to analog data"? Is this a printed document, or a piece of electronics?

Why is it necessary to convert the digital data to analog?

What sort of encoder are you using? Post a link to its datasheet.
