How to count and stop at multiple encoder locations

[Jessica D]

Hello, I was given an assignment at school to create an encoder-based stepper motor driven wheel to be stopped at multiple preset locations as established in a simple list and controlled by a M series board (PCI-6221). The task involves a spreadsheet created list of locations (Stop locations) on the encoder where the stepper motor will need to advance to, stop for a preset period then advance to the next encoder location and so on until the list of locations is completed.

Specifics

1 stepper enable line to run motor that spins the wheel

1 quadrature input pair with reset (Index)

1 Power disable for stepper driver

Period of stop to be from 100msec to 10 sec

I have studied and searched for answers but I am stumped on the stop point list. How can I enter this "stop list" without writing a separate program? According to the teacher, there is a way to do this all in Labview but I can't find it.

Thanks so much for any help you can offer me,

Jessie
