Motor specs and encoder resolution
The 1FL6042-1AF61-0LB1 is a SIMOTICS S-1FL6 servo motor rated for 0.4 kW at 3000 rpm nominal speed, delivering 1.27 Nm continuous torque (M0=1.9 Nm peak). It carries a 20-bit absolute encoder with 12-bit multi-turn resolution — the multi-turn count tracks shaft position across 4096 revolutions without a home cycle, which matters for applications where the machine must know the load position after a power cycle (e.g., pick-and-place, rotary indexing tables). The shaft height is 45 mm, with a feather key and tolerance N, and the motor includes a holding brake — the brake holds the load at standstill but adds inertia; factor that into the acceleration torque budget.
Environmental sealing and drive pairing
The sealing ring is the critical interface; if it's missing or damaged during a swap, the IP rating drops. This motor is explicitly compatible with SINAMICS V70 and V90 drives — the encoder interface and feedback protocol match those drive families without an adapter. No separate encoder converter is needed.
