<div class="markdown_content"><p>Hello everyone:<br/> Thanks for this, when I control motor with codesys 3.5.9,I get a question of "SMC_DI_GENERAL_COMMUNICATION_ERR" at the time of Initializaing the 402axis in sync period of 8ms. and I find that if I set the period less than 8ms, just as 7ms, all things is ok, but when I set this value more than 8ms,then I get this error in Initialization phase.<br/> Does anyboby have occured the same question?<br/> Thanks again.</p></div>
