Siemens 1FL6034-2AF21-1AA1 SIMOTICS S-1FL6 Servo Motor 0.4 kW 230V 3AC 3000rpm

The Siemens 1FL6034-2AF21-1AA1 is a SIMOTICS S-1FL6 servo motor rated 0.4 kW at 3000 rpm, with a rated torque of 1.27 Nm and a 230V 3AC supply. It carries a TTL incremental encoder at 2500 increments per revolution on a 30mm shaft height, an IP65-sealed enclosure, and is built to pair with SINAMICS V90 servo drives.

Selection Notes

The 2500 incr./rev. TTL incremental encoder with feather key and tolerance N fits the SINAMICS V90 standard encoder interface without extra adapter cabling — pair it only with V90 drives set up for TTL incremental feedback, not absolute-encoder variants. The IP65 sealing ring rating suits mounting where washdown or dust ingress is a concern; a non-sealed shaft variant in the same frame would need a drier environment. At 1.27 Nm rated and standstill torque, this frame size targets low-inertia positioning axes rather than heavy load points — step up to the next frame in the family if the application needs materially more torque at 3000 rpm.

Applications

Used as the motor half of a SINAMICS V90 servo axis in machine tools, packaging equipment, and material-handling stations that need compact positioning drives with encoder feedback.
