Motor ratings and encoder — what they mean for your axis
The 1FL6044-1AF61-0LA1: Rated at 0.75 kW and 3000 rpm with a continuous torque of 2.39 Nm, this SIMOTICS S-1FL6 servo motor is sized for light-to-medium duty positioning axes — think pick-and-place, labeling, or small conveyor indexing. The 20-bit absolute encoder (12-bit multi-turn) gives you position feedback down to 0.34 arc-minutes per revolution, enough for repeatability in the 0.01 mm range on a ball-screw stage. The 3.5 Nm stall torque (M0) provides the breakaway margin for accelerating the load from standstill — useful when the axis starts under load or needs a short burst to clear a jam.
IP65 and sealing ring — washdown-ready integration
The sealing ring must be seated correctly at installation; a missing or pinched seal voids the IP rating. No holding brake on this variant — the motor coasts to stop on power loss unless the drive holds position electrically or an external brake is added. Factor this into the axis safety circuit if vertical loads are involved.
Drive compatibility and commissioning note
Designed to pair with SINAMICS V70 and V90 servo drives — the motor feedback cable and power connector pinouts match those drive families directly. The 400 V 3-phase winding connects to the drive output; the 20-bit absolute encoder uses the drive's Hiperface or similar interface (check the drive manual for the exact encoder protocol). Shaft height 45 mm with a feather key and tolerance N — the keyway is standard for this frame size, and the N fit means the key sits flush without play. Mounting dimensions follow the SIMOTICS S-1FL6 mechanical outline; verify the bolt pattern and pilot diameter against the existing machine interface before ordering.
