&lt;p&gt;that usually means that the modulo period, when converted to increments, is larger than 2^31. (The bus bandwidth is usually 2^32.)&lt;/p&gt;
&lt;p&gt;What is your "technical unit", do you program in angular degrees? And what is the modulo period?&lt;/p&gt;
&lt;p&gt;If you want you can post the drive configuration (screen shot of the "General" and "Scaling/Mapping" page).&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;

Has anyone seen this error and actually understands what it means and how to get rid of it?&lt;br/&gt;
I tried to work around it by reducing the number of increments on the drive but then the drive itself starts throwing errors.&lt;/p&gt;&lt;/div&gt;</summary></entry></feed>
