<div class="markdown_content"><p>Hi,<br/> Edwin<br/> Could you show me the result of Read Actual Axis.iRatioTechUnitsNum and Axis.dwRatioTechUnitsDenom on my project?<br/> Because I try to calculate with the same as your method but the result doesn't correct.</p> <p><img alt="IMG: Untitled.png" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4408"/></p> <p><img alt="IMG: Untitled.png" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4407"/></p></div>

<div class="markdown_content"><p>Example:</p> <p>Axis.iRatioTechUnitsNum := Direction (+/-1) * motor turns * gear output turns (all left side) * units in application (all right side)<br/> Axis.iRatioTechUnitsDenom := increments * motor turns * gear output turns (all left side) <br/> <br/> Note: These two values are mathematically reduced, e.g. if iRatoTechUnitsNum=10000 and dwRatioTechUnitsDenom = 200000, it will be…<br/> iRationTechUnitsNum=1 and dwRatiTechUnitsDenom=20</p> <p>BR<br/> Edwin</p> <p><img alt="IMG: Ratio.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=1568"/></p></div>

<div class="markdown_content"><p>Hi thanks for the answer, but I already tried and it changed only a few parts of the config.<br/> Nominator is a dword and denominator a int!<br/> I need more. <br/> As you can see on the image of my first post, I would like it I change the values in the red square!<br/> Does someone know how to perform this?</p></div>

<div class="markdown_content"><p>Hi,<br/> I would like to be able to change all the scaling parameter of my softmotion drive in my Codesys project (in running mode, and not only config one).<br/> not only the inc/motor turns object, but also the gear ratio.<br/> I have an application where the same motor could be used on different station with different scaling.</p> <p>I looked into the axis structure parameter and I only found the MSC_Changegearinratio block.<br/> Does someone know how to do this?</p> <p>Thanks by advance</p> <p><img alt="IMG: 2016" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=1566"/></p></div>
