I am using a LIN R701-R710 stepper motor driver to drive a single stepper motor, but I have having some issues using the NI 9401 and NI 9482 to controller my driver. The issue that I am having is using multiple lines at once to read data as well as write data via DIO of 9401, but when I place my codes into my Main Loop it appears that I am unable to control my relay or change direction. However, this works when I place each section i.e. the relay, direction, and step loops independently on an infinite loop they all work fine. I have attached my code and any help is much appreciated.
LIN R701-R710 Stepper Motor Driver:
I based my program off on some of the NI posts and NI examples, but while I am able to move my motor it is unable to trigger the relay or change direction.
Can you post the code that is working as well as what cDAQ chassis you are using?
