Hi everyone,
I am using the NI 9503 module with a 9006 cRIO to controle a stepper motor using this module to rotatate a number of steps (480 steps) then change the direction of rotation. The frequency of the phase signals should be 200Hz. What I need is a simple drive in open loop. No need of torque smoothing, anti-resonance coefficients, correction angle... etc.
I'am trying using the project example in Labview "NI 9503 Stepper Drive Position Setpoint". I modified it so I can fixe the duty cycle for each phase as a parameter (to 50%). Please find attached whole my project.
The issue is when I run it, the generated signals have a duty cycle less than 50%. You can find oscilloscope captures in the folder "Captures". I dont know what is the problem. Please help me. Thank you very much.
I have Labview 2014 and SoftMotion toolkit.
Best regards
