The holding brake is built in — this motor holds position on a powered-down axis, which matters for vertical loads or any application where the load must not drift when the drive is off. The absolute encoder is 20-bit resolution with 12-bit multi-turn tracking, so the drive knows the shaft position immediately on power-up without a homing routine — saves cycle time on multi-axis machines. ## Shaft, seal, and mounting constraints Shaft height is 90 mm with a plain shaft and tolerance N — the coupling bore and the mating machine interface must match this centre height and the plain shaft diameter (no keyway). IP65 with the sealing ring fitted means the motor body and the shaft seal withstand washdown — suitable for food processing, packaging lines, or any environment where hose-down cleaning is routine. Compatible with SINAMICS V70 and V90 drives — the encoder interface, motor feedback, and power cable pinouts are matched to those drive families, so pairing is a straight cable connection without adapter boards.","metaTitle":"Siemens 1FL6090-1AC61-0LH1 SIMOTICS S-1FL6 Servo Motor","metaDescription":"Siemens 1FL6090-1AC61-0LH1 SIMOTICS S-1FL6 servo motor, 2.5 kW, 400 V 3 AC, 2000 rpm, 11.9 Nm, IP65, holding brake, 20-bit absolute encoder.","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/d5036c209f9f0b10f487ce0fa4ad54c4.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=185466&mlfb=1FL6090-1AC61-0LH1","alternativesUrl":"https://aoctrl.com/api/mcp/products/1FL6090-1AC61-0LH1/alternatives.json"},"ai":{"faq":[{"question":"What is the closest alternative to 1FL6090-1AC61-0LH1 in the SIMOTICS S-1FL6 family?","answer":"The SIMOTICS S-1FL6 family includes other shaft heights and power ratings, but a substitution would require verifying the mounting flange, encoder type, brake voltage, and shaft dimensions against the application."},{"question":"What compliance documentation does Siemens provide for 1FL6090-1AC61-0LH1?","answer":"The evidence does not list specific compliance marks (RoHS, REACH, UL, IEC) for this order code.
