I'm trying to control the position of a stepper motor with labview. I'm using the square waveform vi and trying to count the number of pulses and control the duty cycle to thus control the position of the motor (open loop). However, when running my code, it seems that the feedback node does not output any information above like 3Hz inputted frequency to the square waveform vi. If I remove the duty cycle input to the square waveform vi, it works fine. Because of this problem, the "actual position" indicator does not change. I am directly looking at the feedback node with the signal 4 graph.
