Constant velocity acceleration and deceleration in two axis application

[uconnsenior]

I have a two axis (in this case, two spindles) application that requires one axis to constantly accelerate from an initial velocity to a final velocity, and the other axis to decelerate constantly from an initial velocity to a final velocity.  I no longer have access to NI Motion Assistant, and am looking for assistance, suggestions, or tips as to how to approach this type of coding in LabView.  To further complicate matters, the initial velocity of the first spindle and the terminal velocity of the second spindle will need to be adjustable by a user input located on the front panel.  Any help would be great...thanks.

Hi uconnsenior,

There are many shipping examples in LabVIEW that come with the NI-Motion driver.  You can access them in LabVIEW by going to Help >> Find Examples >> Hardware Input and Output (folder) >> Motion Control.  For instance, the Velocity Profiling example allows the user to set the low and high velocity of a motion system and the One-Axis Move (Accel - Max Velocity - Decel) example completes a single axis move using user-specified acceleration, maximum velocity, and deceleration values.  You can also search on our website for online example code.

Hope this helps,
