## Phidget Motor Velocity Controller.lvlib:MotorVelocityControllerVelocityChangeEventExe.vi

The most recent velocity value will be reported in this event, which occurs when the `MotorVelocityControllerDataInterval` has elapsed.

- Use the `MotorVelocityControllerRescaleFactor` to convert the units of this property to more intuitive units, such as rotations or degrees.
