For Sinamics G, free function blocks are released, approved and supported. but for sinamics S, free functions are released, but are not supported nor recommended. Also, if this function you require is in any way meant to be safety related, then it should not, must not be relied upon. That aside, once the FFBs are released, you can use an LVM (p20266) free function to monitor the DC link voltage r70 (or r26 with smoothing) and then set the higher/lower-than outputs to your digital outputs. You will need to play with the trigger levels & hysteresis p20267 - p20269. Regards, Graeme
