This torque profile suits direct-drive or low-backlash gearing on indexing, winding, and pick-and-place axes where the load torque at speed stays within the continuous MN band and peak acceleration draws from the M0 margin. The 20-bit absolute encoder (12-bit multi-turn) eliminates the need for a homing cycle on power-up — the axis position is retained across a bus voltage loss, provided the backup battery on the SINAMICS V70 or V90 drive is maintained. This is critical for a GMP line where a lost position reference after a power cycle would require re-qualification of the axis travel limits. The sealing ring must be seated correctly at installation to maintain the IP65 rating; the gland plate entry for the motor cable also needs a matching IP65-rated fitting. ## Sourcing and lifecycle — active, traceable, quoted to order The motor is a spare part within the SIMOTICS S-1FL6 family, designed for direct compatibility with SINAMICS V70 and V90 drive converters. For a BOM freeze or a controlled change in a validated line, this part is qualifiable and traceable — the nameplate data supports the audit trail from PO to installed unit.","metaTitle":"Siemens 1FL6066-1AC61-0LG1 SIMOTICS S-1FL6 Servo Motor","metaDescription":"Siemens 1FL6066-1AC61-0LG1 SIMOTICS S-1FL6 servo motor, 1.75 kW, 2000 rpm, 11 Nm stall torque, 20-bit absolute encoder, IP65, active production, available to","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors with Brake"],"specifications":{"lifecycle_stage":"current"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"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=143649&mlfb=1FL6066-1AC61-0LG1","alternativesUrl":"https://aoctrl.com/api/mcp/products/1FL6066-1AC61-0LG1/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FL6066-1AC61-0LG1","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/1FL6066-1AC61-0LG1 when reusing this data.
