Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The 1FL6042-2AF21-1LG1 is a Siemens 1FL6-series servomotor for SINAMICS V90 drives, rated at 750 W with 2.39 Nm of rated torque at 3000 rpm. It carries a low-inertia rotor, an absolute encoder system (20-bit single-turn plus 12-bit multi-turn), and an IP65 enclosure for washdown or dusty environments. This motor is designed for dynamic positioning and speed control in servo applications. The low-inertia rotor (0.897 kgcm² moment of inertia) allows rapid acceleration and deceleration, making it suitable for short-stroke pick-and-place or indexing moves. The absolute encoder retains position after power loss without a homing cycle, simplifying commissioning on multi-axis machines. Rated torque of 2.39 Nm at 3000 rpm maps to the 750 W power rating; the natural cooling design means no external fan, reducing maintenance but requiring adequate free air around the motor body. Siemens has classified the 1FL6042-2AF21-1LG1 as phase-out, with a formal discontinuation date of 2025-10-01. After that date, Siemens will no longer manufacture or support this order code. Buyers should evaluate last-time-buy quantities or identify a successor within the 1FL6 family for ongoing production needs.","metaTitle":"Siemens 1FL6042-2AF21-1LG1 1FL6 Servomotor, 750 W, 2.39 Nm, IP65","metaDescription":"Siemens 1FL6042-2AF21-1LG1 1FL6 servomotor for SINAMICS V90: 750 W, 2.39 Nm, 3000 rpm, absolute encoder 20+12 bit, IP65, plain shaft, phase-out Oct 2025.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":[],"specifications":{"Group Code":"R220","Product Group":"3585","Product class":"C: products manufactured / produced to order, which cannot be reused or re-utilized or be returned against credit.","Quantity Unit":"1 Piece","Product Family":"1FL6 servomotors for SINAMICS V90","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : N","Packaging dimensions (L x W x H)":"316.00 x 182.00 x 170.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 08-01-16","REACH Art. 33 Duty to inform according to the current list of candidates":"Reach Information"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$609.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/0a4c50cfb101f16b3cf0155b40d7cbe3.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/1FL6042-2AF21-1LG1/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FL6042-2AF21-1LG1","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/1FL6042-2AF21-1LG1 when reusing this data.
