Question
FOC Open Loop reverse
Posted on January 28, 2016 at 19:23
Hello,
I'm currently using Open loop mode for debugging my hardware, current readings and such. I have found by trial and error the best values for the offset and slope of the V/f curve, such that the motors work on the full range of speeds. However, when I set negative velocities through MCI_ExecSpeedRamp(MCI, Vel, time), the motors do not behave the same as in the positive direction. If I replace my offset and slope values by the default ones, the motors behave similarly in both directions. Am I missing some step to make Open loop work with my V/f curve? On another topic: How can I obtain the confidential distribution of FOC SDK? I've phoned ST's sales, which directed me to my local distributors. I've contacted several distributors on my country. A couple were unhelpful, others had no idea what I was looking for. A couple others said they would redirect my request to ST. So far I was not able to find anyone who could help me. How can I contact in ST to help me obtain the SDK? Best regards #openloop
