The -1SB3 shaft-side code points to a plain shaft without brake in the standard encoder configuration; the motor carries the Siemens incremental encoder resolver option typically used for absolute position feedback to the drive (cites:). ## Mechanical envelope and panel-side handling Mounting is the standard Siemens 1FK7 flange footprint with the drive-end cable entry for the power and signal cores routed to the SINAMICS terminal box; commissioning engineers should follow the Siemens EMC and grounding guidance in the 1FK7 documentation set when integrating into a SINAMICS line-up (cites:).","metaTitle":"Siemens 1FK7032-5AK71-1SB3 Servo Motor, 1.37 kg, obsolete","metaDescription":"Siemens 1FK7032-5AK71-1SB3 servo motor, discontinued 01.10.2019.
