1.75 kW at 2000 rpm — what the numbers mean for a motion axis
The 1FL6066-1AC61-0LB1 is a SIMOTICS S-1FL6 servo motor rated 1.75 kW at 2000 rpm rated speed, with an 11 Nm stall torque (M0) and 8.36 Nm rated torque (MN) — the stall figure tells you the holding torque at zero speed for a clamped axis, while the rated torque is what the motor delivers continuously at rated speed without overheating. The 20-bit absolute encoder (12-bit multi-turn) gives position feedback down to 0.00034° per count on a full revolution, and remembers the shaft position across power cycles — no homing routine on restart, which matters for a gantry or rotary table that must pick up where it left off. The holding brake holds the vertical axis at standstill when the drive is disabled — the brake is sized for the 11 Nm stall torque, so a Z-axis load that exceeds that will back-drive through the brake.
IP65 and shaft height — mounting constraints on a washdown line
IP65 with the sealing ring means the motor body and the shaft seal resist hose-directed water — suitable for food-and-bev washdown zones, but the cable gland at the connector end must be torqued correctly or the seal is broken. Shaft height 65 mm (flange size N) with a feather key — the mounting footprint matches the standard SIMOTICS S-1FL6 frame, so a machine designed for a 65 mm shaft-height servo accepts this motor without adapter plates. Compatible with SINAMICS V70 and V90 converters — the motor thermistor and encoder interface are pre-configured for those drive families, so the commissioning parameter set is a matter of entering the motor data from the nameplate, not tuning from scratch.
