Also, we found few cobras constantly going to nowhere during convergence tests. According to our experience in ASRD during AIT phase, re-calibrate those cobra usually helps them get back to healthy. Therefore, a close inspection on those suspect cobra is needed.</p> INSTRM-1560

Inspect the suspect cobra before engineering run

Further calibration like on-time, geometry and motor map will be carry out after we finishing the inspection on bad cobra before delivery.</p> <p>The file <span class="nobr"><a href="https://pfspipe.ipmu.jp/jira/secure/attachment/15177/15177_INSTRM-1560.ipynb" title="INSTRM-1560.ipynb attached to INSTRM-1560">INSTRM-1560.ipynb^{<img class="rendericon" src="https://pfspipe.ipmu.jp/jira/images/icons/link_attachment_7.gif" height="7" width="7" align="absmiddle" alt="" border="0"/>}</a></span> showing how we re-activate the cobra.</p> <p>Here is the new XML after re-activating the cobra marked as bad after the delivery.<br/> <a href="https://github.com/Subaru-PFS/pfs_instdata/blob/master/data/pfi/modules/ALL/ALL_final_20220505_mm.xml" class="external-link" rel="nofollow">https://github.com/Subaru-PFS/pfs_instdata/blob/master/data/pfi/modules/ALL/ALL_final_20220505_mm.xml</a></p> <p>Following discussions with <a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=chyan" class="user-hover" rel="chyan">chyan</a>, this ticket is considered done.</p> Relates INSTRM-1554 INSTRM-725 Development Rank 0|02qpjd:00r Sprint PreEngRun05 E PreEngRun05 G Story Points 2.0
