In SS1 the STO (or removal of power) from the axes are delayed for a certain time allowing a controlled rampdown. This makes it possible to stop moving axes in a controlled way and disable of drives before the power is interrupted (or STO triggered). This will result in a safer system and less harware failures and error messages. -Basically the safey system is interfaced with binary signals (ethercat I/O). If, for instance, an emergency stop button is pressed the safety system immediately commands this plugin to rampdown velocity of axes (that a configured to stop). When all axes, that are configured to rampdown, have stopped then this plugin will disable the axes and set an ethercat output informing the safety system that the axes are standstill. After a certain timout the safety system will make sure power is removed from the motion axes by STO or removing power. The removal of power to triggering of STO will made regardless if the axes are stanmding still or not. A reset of the safety system will only be possible once teh safetry system gets a confirmation that all axes are at rest. +Basically the safey system is interfaced with binary signals (ethercat I/O).
