<div class="markdown_content"><p>Hello,</p> <p>you need to use poscontrol other wise you do not have the PID Loop fot Controlling your analog drive.</p> <p>Encoder and virtual axis are Independent from that - and used as 'virtual' axis , encoder as encoder axis - both could be for example connected as master axis for caming or mc_gearin. mc_phasing etc.</p> <p>BR<br/> Edwin</p></div>

<div class="markdown_content"><p><em>Originally created by:</em> rettore84</p> <p>Thank you Edwin,</p> <p>One question that I have is, the SM_Poscontrol module has a PID loop configurator for speed/position control, while SM_Drive_virtual and Sm_Free_Encoder don't, but I suppose I could still use them, in that case, how is the position/speed controlled?</p></div>

<div class="markdown_content"><p>Hi,<br/> yes exactly, <br/> if this is determinitic it might work,<br/> it is an option to chose these ethercat modules from the posControl poject example.</p> <p>BR<br/> Edwin</p> <p><img alt="IMG: PosControl.jpg" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=3429"/></p></div>

<div class="markdown_content"><p><em>Originally created by:</em> rettore84</p> <p>The default RPI is 10ms, and not sure how deterministic this will be. Is this what you were asking?</p></div>

<div class="markdown_content"><p><em>Originally created by:</em> rettore84</p> <p>Hi All,</p> <p>I have two old Yaskawa SGDA servo packs with no Fieldbus communications, with an analog input for speed reference and an incremental encoder output. I'm using a Raspberry Pi 3, with Ethernet/IP and a Wago 750-352 EIP IO rack with two Encoder inputs and two -/+10V analog output modules.</p> <p>My intent is to use the CNCTable project example with my setup. The example project uses the SM_Drive_Virtual, I suppose I cannot tie the Wago IO to the parameters of SM_Drive_VIrtual. </p> <p>I found the POSCOntrol project example where the parameters of SM_POSCOntrol, <strong>in.wActPosition</strong> and are tied to an Ethercat Buscoupler with an analog output module and encoder input module.</p> <p>My question is, would it work if I replace SM_drive_Virtual in the CNCTable project with SM_PosControl, use the POSCOntrol axis with the SoftMotion function blocks, in the CNCTable project, and tie <strong>in.wActPosition</strong> and to my IO?</p> <p>Thank you.</p></div>
