The Siemens 6SL3544-0QB02-1MA0 is a SINAMICS G110M Control Unit CU240M with an AS-Interface Q interface, designed for distributed drive applications where the control electronics need to live right at the motor, not back in the cabinet. IP65 means the housing and the plug-in connections tolerate washdown environments — food-and-bev, packaging, material handling lines where dust and hose-down are daily. The unit handles motor frame sizes 100/112, so it pairs with the corresponding Power Module (sold separately) for a complete drive package.
I/O and signal routing
Onboard I/O includes 4 DI, 2 DO, 2 AI, and 1 F-DI for PTC/KTY connection. EM brake control is integrated.
Mounting and integration
Dimensions are 105 x 205 x 171 mm (HxWxD) without the Power Module. The plug-in connections are AS-Interface Q-coded, so verify the network segment can supply the control unit's bus power. Mounting is direct to the motor or a nearby bracket — no DIN rail required, which saves panel space when the drive is distributed along the line.
