I have Extended functions for Safety, and i don't know whats the correct order to enable/inhibit the signals for enabling the axis. Thanks in advance, Best regards, Joseba

If possible you can interrupt the positioning task first and then activate the safety function. You can abort positioning by using intermediate stop or reject traversing task. Please have a look at section 8.8 of the function manual for more information about this. https://support.industry.siemens.com/cs/ww/de/view/109740020/en?dl=en If this is not possible you have to consider the recommendation stated in section 4.2.5.1 of function manual safety, that OFF2 is not permitted if you are using SS1 for ESTOP. https://support.industry.siemens.com/cs/ww/de/view/109740018/en?dl=en
