Servo motor on a feed axis or spindle drive
The Siemens 1FT2208-3AC90-2RB0-Z L1A+Q01 is a SIMOTICS S-1FT2 CT synchronous servo in the compact class, sized at 18 Nm holding torque (M0=18 Nm) and 3.05 kW mechanical output at nN=2000 r/min — the kind of motor that drops onto a machine-tool feed axis, a packaging-line servo pump, or a converting-line unwind where a holding brake is part of the move profile, not an option to retrofit. Feedback is resolver 2-pole with an integrated Pt1000 in the stator windings — resolver gives absolute position without battery, and the Pt1000 lets the drive's thermal model clamp current before the insulation class hits its ceiling; the suffix block L1A+Q01 is a factory build configuration applied on top of the base 1FT2208-3AC90-2RB0-Z part number, not a separate SKU.
Connectors, shaft interface, panel-side fit
The motor carries a signal connector M17 (resolver + Pt1000 leads) and a power connector M23 (phase + brake) — both pre-wired at the factory, so the cabinet side needs the matching Siemens SPEED-CONNECT mating connectors and the motor cable stays one continuous run, no separate brake wiring to land in the panel. Because the part is class C (products manufactured to order and non-returnable), the connector orientation, cable exit, and shaft/keyway are locked in at order entry — re-specifying the L1A+Q01 options after build is not possible, so confirm the option code against the machine drawing before the order releases.
Order code, lifecycle, and sourcing posture
Because the unit is built to order, pricing is quoted against the configured order code with the L1A+Q01 option block spelled out; availability and lead time are confirmed at RFQ through independent distribution rather than off-the-shelf stock.
Compliance documentation on the file
For the documentation file, Siemens provides RoHS compliance with the date stamp 11-02-21 and REACH Art. 33 candidate-list information tied to the part; both are the standard declarations expected for a 1FT2-series servo on a machine shipped into the EU market today.
