## Phidget Stepper.lvlib:StepperSetAcceleration.vi

The rate at which the controller can change the motor's `Velocity`.

- Units for `Position`, `Velocity`, and `Acceleration` can be set by the user through the `RescaleFactor`.The `RescaleFactor` allows you to use more intuitive units such as rotations, or degrees.
- The default units for this motor controller are 1/16steps per count.
- Changing the acceleration value while the stepper is in motion (especially at speeds higher than 1000 1/16th steps/s) can cause unpredictable results due to the inability of the processor tocalculate a new acceleration curve quickly enough. Generally you should wait until the motor is stationary until calling this function.
