in general there two solutions to do motion.<br/>
Either the drives calculate the trajectory - you comand it (set where to go how fast and give the start)<br/>
or in case of SoftMotion where you calc cyclic setpoints for all axis -> it is more or less mandatory to have this Kind of supervision of the motion<br/>
calculation (if the fb is not executed anymore-> goto an errorstate)<br/>

<p>As every plc-codesys manufacturer implements his own plcopen motion libraries which make codesys motion projects not portables, I am developing my own plc motion library.</p>
<p>My question is.</p>
<p>I can see that if an fb like mc-moveabsolute (or any other, like move_relative...) Is not executed every cycle when it has the axe control the axe goes to error. Does it be standard mandatory?. If yes, Why?</p>
<p>For example: If a I am working with sfc, it make me possible to launch an fc_moveabsolute in one step and when the movement beguins transition to another step to do other things. In next step I can control if the movement has finished.</p></div>
