Hello everybody! I would appreciate anyone's help regarding this issue. I'm using AI X177.25-26 as a main speed reference for DCM drive (6RA8078-6DV62-0AA0). The problem is when I have 0V for speed reference, DCM registers about 2mV (possible some noise) casing drive to move very slow which I want to avoid. Is there any way to make a kind if dead band (with 10mV) around zero speed reference (0V) or any other way (making AI not listen signal below 10mV) to avoid this. Switch On/Off1 and Enable operation are active all the time. Thanks in advance. Marko ------------------------------------------------------------------------------------------ |
