The 20-bit absolute encoder (12-bit multi-turn) gives 1,048,576 positions per revolution — enough resolution to close the position loop on a ball-screw axis without a secondary linear encoder, keeping the handshake timing within the cycle budget. ## Holding brake and IP65 for vertical-axis and washdown lines The integrated holding brake holds the shaft at standstill — essential for vertical Z-axis loads where the load can back-drive the motor when power is removed. The IP65 degree of protection with sealing ring means the motor body and encoder connector withstand directed water jets and dust ingress, suiting food-and-bev washdown zones or coolant-laden machining environments. ## Drive compatibility and shaft interface This motor is designed to pair with SINAMICS V70 and V90 servo drives — the 400 V 3-phase winding matches the drive output stage, and the 20-bit absolute encoder communicates position and speed feedback over the drive's encoder interface without a separate feedback converter. The shaft height is 45 mm with a feather key and tolerance N, so the motor mounts to standard metric frame dimensions and the key transmits torque to the coupling without slip.","metaTitle":"Siemens 1FL6044-1AF61-0LB1 SIMOTICS S-1FL6 Servo Motor","metaDescription":"Siemens SIMOTICS S-1FL6 servo motor, 0.75 kW, 3000 rpm, 2.39 Nm rated torque, 20-bit absolute encoder, holding brake, IP65.
