<div class="markdown_content"><p><em>Originally created by:</em> <em>gnom4</em></p> <p>Recently a library for Nanotec PD4-C has been issued with sp10 but the drive does not work well while in constant speed.</p> <p>While the drive is accelerating or decelerating all seems fine, but while it reaches constant speed during movement it apears like it would have a short brake(bump) every second or so during movement (maybe the position is not exact as it should be and codesys tries to correct it so the motor behaves like that – I think so bacause when I use open loop it is rotating fine without this symptom – but I need closed loop).</p> <p>Also after finished homing the mode in the drive changes to 8 but it still shows homing on the MC_HOME and it needs reinit for further operation.</p> <p>Drive is connected to a can network, changing sync time does not resolve the issue. (tested using licensed softmotion CNC PLC).</p> <p>Any clues how to resolve it.</p> <p>PS. Other drive types connected to the same PLC work fine (also while in synchonized movement with PD4-C).</p></div>
