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.","metaTitle":"Siemens 1FL6066-1AC61-0LB1 SIMOTICS S-1FL6 Servo Motor","metaDescription":"Siemens 1FL6066-1AC61-0LB1 SIMOTICS S-1FL6 servo motor, 1.75 kW at 2000 rpm, 11 Nm stall torque, 20-bit absolute encoder, IP65.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FL6066-1AC61-0LB1","description":"****spare part**** SIMOTICS S-1FL6-1FL6 operating voltage 400 V 3 AC PN=1.75 kW; NN=2000 rpm, M0=11 Nm; MN=8.36 Nm shaft height 65 mm absolute encoder 20-bit (12-bit multi-turn) with feather key, tolerance N with holding brake degree of protection IP65 with sealing ring compatible with the converters SINAMICS V70&V90","lifecycle_stage":"current"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/67c698c28b6924e6bf19ef874458d160.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=160307&mlfb=1FL6066-1AC61-0LB1"},"ai":{"faq":[{"question":"What is the 20-bit absolute encoder on this motor?","answer":"It is a 20-bit absolute encoder with 12-bit multi-turn resolution — 1,048,576 positions per revolution, and the multi-turn tracks up to 4096 shaft revolutions.
