Vandervell Posted April 25, 2016 Share Posted April 25, 2016 Hello, I bought a stepper motor without encoder (it's a mistake). I have a question: is it possible to control a motor in a coordinate system without encoder (without read-back) with Geo Brick LV IMS II? Have a nice day. Best regards.

Omron Forums Support Posted April 25, 2016 Share Posted April 25, 2016 Yes, see pages 152 - 166 of the Geo Brick LV Manual: http://www.deltatau.com/manuals/pdfs/GEO%20BRICK%20LV.pdf?id=635787783281577417 Link to comment Share on other sites More sharing options...
Vandervell Posted April 26, 2016 Author Share Posted April 26, 2016 Thank you for your answer. If I understand well, the principle is to simulate the feedback position by integrating the velocity of the motor? Link to comment Share on other sites More sharing options...
Alex Anikstein Posted April 26, 2016 Share Posted April 26, 2016 Yes. The key is that it uses the commanded velocity as if it were measured velocity coming from an external sensor. Link to comment Share on other sites More sharing options...
Vandervell Posted May 20, 2016 Author Share Posted May 20, 2016 Hi, I followed the procedure frome pages 156 to 166 but I have an error with the "phasing search error". Do you have any idea where that error comes from ? Have a nive day, Victor Link to comment Share on other sites More sharing options...
Richard Naddaf Posted May 20, 2016 Share Posted May 20, 2016 This error indicates that you may have not set up the power-on phasing parameters (Ixx81, and Ixx91). The complete procedure is from page 158 through 165. Please, make sure that you have all the settings covered. Link to comment Share on other sites More sharing options...
