In the attached screenshot, the persistent position data is not able to store the 0 values of the axes when I zero them using Set_Position FB but, still, it is storing the initial values of the motors. How to move forward with this?</p> <p><img alt="IMG: Screenshot from 2019" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=4986"/></p></div>

<div class="markdown_content"><p>Hi Kanishk,</p> <p>Using MC_GroupSetPosition doesn't work because when you power up drive and motor after they're off, Codesys will receive the absolute position from the encoder.<br/> I think you should find the parameters of your drive that can perform a preset position and then using FB which can force the value of the parameters. </p> <p>hope it will be useful for you</p> <p>with regards</p></div>

When I cycle the power of the system the motors' position is unchanged which was earlier set to '0' by using the MC_Setposition FB as suggested. I kindly request you to please help me out with this.</p> <p>PS is there any FB which retains the position to a set value even after the cycle power is done?</p> <p>with regards,<br/> Kanishk Navale</p></div>
