It's a spare-part variant — same frame, same windings, same encoder as the production motor, sold as a replacement unit for field swap. Shaft height is 45 mm with a plain shaft (no keyway, tolerance N), so the coupling bore must be sized for a slip fit. No holding brake — the load holds position through the drive's holding current or an external brake. ## Encoder resolution and what it means for positioning The absolute encoder is 20-bit single-turn with 12-bit multi-turn resolution — that's 1,048,576 counts per revolution, with 4096 revolutions tracked before the multi-turn counter wraps. For a ballscrew-driven axis, this gives sub-micron position feedback without a home cycle on power-up. The 12-bit multi-turn means the motor knows its absolute position across 4096 shaft turns. If the machine has a multi-turn range exceeding that (e.g., a long conveyor or rotary table), the drive must handle the wrap or a different encoder variant is needed. ## IP65 and sealing ring — where this motor runs Degree of protection IP65 with the sealing ring fitted — the motor body and shaft seal are rated against dust ingress and low-pressure water jets. That puts it in washdown zones, food processing areas, and outdoor cabinets where a standard IP54 motor would draw moisture through the shaft seal. The sealing ring is a separate part — if the motor arrives without it installed, the IP65 rating is not effective until it's seated. Check the shaft end before commissioning. ## Drive compatibility — SINAMICS V70 and V90 This motor is explicitly compatible with SINAMICS V70 and V90 servo drives. The 400 V 3 AC winding matches the V90 400 V class drive; the 20-bit encoder interface is native to both drive families — no adapter module needed. Motor cable and encoder cable are ordered separately. The V90 drive's motor connector pinout matches the S-1FL6 connector; the encoder cable uses the standard Siemens 20-bit absolute encoder pin assignment. No wiring adapter required. No stock-holding claim; lead time depends on the order quantity and Siemens factory load.","metaTitle":"Siemens 1FL6042-1AF61-0LG1 SIMOTICS S-1FL6 Servo Motor","metaDescription":"Siemens SIMOTICS S-1FL6 servo motor, 0.4 kW, 3000 rpm, 1.27 Nm, IP65, 20-bit absolute encoder, plain shaft.
