<div class="markdown_content"><p>Hi Edwin,<br/> Update on the troubleshooting.</p> <p>Got EL7041-0000 Revision 23 working with the following Softmotion Driver</p> <p><strong>EL7041 1 Ch. Stepper motor output stage (50V, 5A) Rev22</strong></p> <p>Is it good to assume that the hardware revision need to be higher than software revision for Softmotion to work.</p> <p>From initial testing looks like basic things like enable and motion seems to work.</p></div>

<div class="markdown_content"><p>Hi Edwin,<br/> Somehow I cannot edit the EtherCAT I/O mapping in the EL7041.</p> <p>Any hint that you can give me on how to control the Stepper Driver?</p> <p>Ideally working in Softmotion be best case. Thanks.</p></div>

<div class="markdown_content"><p>Hi Edwin,<br/> So I did rescan again. This time I did the Device XML install from Beckhoff and find that it's now EtherCAT network is back working.</p> <p>How do I make it such that Softmotion can use the drive?</p> <p>More detail on hardware:<br/> EL7041-0000 Revision 23</p> <p>Current Process Data:<br/> Used to be Velocity was checked, I change it to POS Control<br/> All other still default</p> <p>Saw on the EtherCAT I/O mapping that I am able to control with variables?</p></div>

<div class="markdown_content"><p>no, no twincat needed for 7041..but check the revision in the scan and plc log. Seems different device verion, installed and real hardware</p></div>

<div class="markdown_content"><p>Hi Edwin,<br/> The one scanned only showed as a grey box and do not have SM_Drive on it. By itself it also does not have EtherCAT to scan. Do I need to connect to TwinCAT and change to certain configuration?</p></div>

<div class="markdown_content"><p>does a scan on Ethercat master lead to a valid/same configuration, there are many firmware revisions out in EL7041.</p></div>

<div class="markdown_content"><p>Hi There,<br/> I am trying to get EL7041 Stepper Driver to work.</p> <p>My environment:<br/> Raspberry Pi MC<br/> EK1100<br/> EL7041, connected to Beckhoff Stepper Motor With Encoder<br/> Codesys 3.5.7.10</p> <p>Once I added the EL7041 1Ch Stepper Motor Rev24 with external Encoder, the EtherCAT bus stops working.</p> <p>On the log I get the attached error. Are there an implementation step that I can follow? Supposedly this is a supported drive for Softmotion. Thanks.</p> <p>P.S.<br/> Prior adding the EL7401 I am able to do motion with EL7221 with no issue<br/> [-img src=Device Tree.PNG width=50%: missing =-][-img src=Device Tree.PNG width=50%: missing =-][-img src=Device Tree.PNG width=50%: missing =-]</p></div>
