<div class="markdown_content"><p>Hi transcend,</p> <p>most likely cause: one of the motion FBs was not called in each IEC cycle.</p> <p>See <a href="https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_basic_common_errors.html." rel="nofollow">https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_basic_common_errors.html.</a></p> <p>A different possible error, if you are using buffermode buffered or blending: the execution order of the motion FBs was wrong.

<div class="markdown_content"><p>Hello everyone, I am building a 3-axis packaging machine. First, I created a virtual axis and connected the knife to the virtual axis using a CAM. I also linked the conveyor system to the virtual axis with GearIn. However, I’m facing the following issue: when I use SUPERIMPOSED to change the conveyor’s motion, I get a COMMAND ABORTED error. The exact error is: SMC_ERROR.SMC_FB_WASNT_CALLED_DURING_MOTION. Why am I getting this error?</p></div>
