Is it possible to change the speed while the motor is moving?

I am using Matlab to interface with the VXM controller to control an XSlide. I can set the speed and then move the motor, but what I want to be able to do is set up a control system where the speed changes based on the readings I am getting off of an external force sensor.

I tried breaking it up into a lots of small move commands with a change speed command between each one, but that resulted in very jerky movement. The time when it was processing the next command was too large. I want the movements to be reasonably continuous. Is there a way to do this? I don't currently have an I/O auxiliary breakout cable. Would I be able to do this with that kind of connection?

"Speed-On-The-Fly" is not possible.
The closest thing to it would to set up your speed changes in a "Continuous Index" (See Users Manual P.40 for details)
