You may need to control a stepper motor drive (step or direction) using the digital outputs of your USB DAQ. This article will help you control the motor for some simple moves in LabVIEW.

  1. Make sure you have connected all the necessary wiring and provided sufficient power to the motor.
  2. Refer to this example to perform some basic stepper motor controls, such as direction change and step pulse generation.

Note: Keep in mind that if you do choose to use your DAQ device to control a stepper motor, you will need to consider the following:

  • There is no Motion API, so you will be controlling every part of the pulse train yourself (per the above example).
  • If using feedback, you will need to manually decode the encoder data.
