<p>Anyway I don't use decoder but the other way "OutQueue".</p>
<p>Is it possbile to modify the direction from "shortest" to "positive" directly?</p>
<p>Thank you in advance.</p></div>influence the direction into CNC motion2020-02-27T13:49:29.889000Z2020-02-27T13:49:29.889000Zeschwellingerhttps://forge.codesys.com/u/eschwellinger/https://forge.codesys.com46510799eb64077ea3855fd5a84670d9a6a35bcf<div class="markdown_content"><p>Hi,<br/>
The user can specify a period for the axes A, B, C, P, Q, U, V and W by setting the word PA, PB, PC and so on. By default these are 0, which means: finite and not modulo.<br/>
e.g. N0 PA360 (this means that A has a period of 360 degree).<br/>
Then, the decoder will modify ist behaviour in the way, that the additional axes always travel tot he nearest point. E.g:<br/>
N0 PA360<br/>
N0 G92 A270 (set the position of A axis to 270)<br/>
N0 G1 A0<br/>
This will move the axis in positive direction.</p>
<p>The position output of the ipo is not in the interval <span>[0..Periodlimit]</span>, but can be outside of it. However, the FBs like SMC_ControlAxisByPos will take care of making the modulo.</p>

I'm doing a project where 5 module axes, 0-360, and they are moved with CNC motion.<br/>
I use: <br/>
smc_smoothpath -> smc_extendedcheckvelocity -> smc_checkvelocities -> smc_interpolator and then smc_controlaxisbypos.</p>
<p>But I have a little question: can I set the direction of the axes in positive value?<br/>
If I set the movement from 350 to 5, it does a backwards movement, instead I would a forward movement.</p>
<p>Can anyone help me?</p>
<p>Cheers</p></div>
