It belongs to the 1FL2 servomotor family paired with the SINAMICS S200 drive platform, which sets the cable, connector and parameter defaults the rest of the axis inherits. Product class is built-to-order — each unit is configured and manufactured against the order, so it cannot be returned against credit; confirm the shaft, encoder and connector variant match the drawing before release. ## Nameplate ratings and what they mean on the line Supply voltage 400 V 3AC with a rated power Pn of 1.5 kW and rated speed Nn of 2000 rpm — a mid-range axis point that covers indexing tables, small CNC spindles and packaging feeders without stepping up to the larger 1FL2 shaft heights. Stall torque M0 of 8 Nm against a rated Mn of 7.16 Nm means the motor holds nearly all of its rated torque at standstill, which is the figure that decides whether a short dwell-and-cut motion stalls the line; the small drop between M0 and Mn also points to a relatively flat torque curve across the speed range. The 21-bit absolute encoder mounted in the angular AM21 connector gives the SINAMICS S200 the position resolution needed for tight registration moves; mismatched connector orientation between the motor and the drive-side cable is the most common field wiring fault on this series. IP65 with oil seal on a shaft height of 65 mm housing means the motor tolerates coolant splash and cutting-oil mist typical of a machine-tool envelope — the oil seal is the wear part, so spec a replacement seal in the spares kit for any axis near a chip pan. ## Drive pairing and system-level fit Siemens lists this motor specifically as matching the SINAMICS S200 drive, so the drive-side firmware profile, cable cross-section and braking-resistor sizing can all be pulled from the S200 selection tables rather than re-derived. Shaft height 65 mm with a keyed shaft (tolerance N) and no holding brake means the axis must hold position with the drive's own torque — for vertical loads, either re-spec the -1MB1 brake variant or confirm the mechanics back-drive safely on a power loss. ## Compliance and documentation on file RoHS compliance has been declared since 01-01-18 and the part carries the current REACH Art. 33 candidate-list information, so EU ship-to paperwork is unblocked; export control is AL:N / ECCN:N, which keeps cross-border paperwork light for most destinations.","metaTitle":"Siemens 1FL2306-4AC01-1MB0 Servo Motor, 1.5 kW, IP65","metaDescription":"Siemens 1FL2306-4AC01-1MB0 SIMOTICS S-1FL2 servo motor, 1.5 kW, 400 V 3AC, IP65 with oil seal, paired with SINAMICS S200.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors"],"specifications":{"title":"1FL2306-4AC01-1MB0","Group Code":"R220","description":"SIMOTICS S-1FL2 Supply voltage 400V 3AC Pn=1.5kW;Nn=2000rpm M0=8Nm;Mn=7.16Nm Shaft height 65mm With angular connector AM21bit With shaft key, Tolerance N Without holding brake Protection class IP65 with oil seal Matching drive SINAMICS S200","Product Group":"X0DM","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":"1FL2 servomotors for SINAMICS S200","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : N","Packaging dimensions (L x W x H)":"392.00 x 269.00 x 286.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 01-01-18","REACH Art. 33 Duty to inform according to the current list of candidates":"Reach Information"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/bb4953ac354162275d03ca65ac3f136e.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FL2306-4AC01-1MB0?tree=CatalogTree"},"ai":{"faq":[{"question":"What is the lead time and price for 1FL2306-4AC01-1MB0?","answer":"Built-to-order product class means each unit is configured and produced against the order — we quote price and lead time against the BOM quantity through an RFQ rather than off shelf stock."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FL2306-4AC01-1MB0","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/1FL2306-4AC01-1MB0 when reusing this data.
