What is the speed control logic within NI9514?

Hi guys,

 

I'm using NI9514 to control a servo mortor, but the control logic just confuses me. I used Straight-Line-Move block to give a certain velocity to motor and the motor does follow the velocity(though with oscillation in a small amplitude). But what's strange is that there is no velocity control loop in the axis configuration, so what is the real thing that's controlling the speed? Is it that the velocity just got integrated to position? The axis configuration is listed as below. Any reply is appreciated!
