<div class="markdown_content"><p>Hi.<br/> I have a CNC program with an virtual axis with the dynamic limits Vel= 1000, Acc and Dec=10000.<br/> When I call the function block ControlAxisByPos I notice that small position Changes are applied without the set fGapVelocity, fGapAcceleration and fGapAcceleration resuting in very rough behavior. As soon as the position step is big enough, &gt; about 1 mm then the set acc and dec is applied. I have tried both with and without bAvoidGaps. Please see the atttached trace when I use very low fGapAcceleration and fGapAcceleration (2 mm/s2).<br/> Has anyone else noticed the same behavior and knows what to do about it?</p> <p>Hopful for help.<br/> Best regards<br/> Anders</p></div>
