Siemens 6SN1118-0DM11-0AA1 is a SIMODRIVE 611-D plug-in closed-loop control unit designed for two axes in digital-drive configurations. The 2-axis variant provides closed-loop control for the feed drive (FDD) and main spindle drive (MSD) paths without an integrated direct measuring system. As a spare-part module for legacy SIMODRIVE 611-D installations, it enables dual-axis servo control in machines that rely on the SIMODRIVE 611-D architecture.
