It delivers 1.3 Nm rated torque at 3000 RPM from a DC 600V bus, using a 20-bit absolute encoder for position feedback. Natural air cooling keeps the enclosure simple — no fan to fail on a washdown line. Rated torque of 1.3 Nm and speed of 3000 RPM size it for light-to-medium indexing or positioning axes — think pick-and-place, small conveyor segments, or labeling stations. The DC 600V input ties it to a common DC bus, typical of multi-axis SINAMICS S120 cabinets. The 20-bit absolute encoder means no homing cycle on power-up; the drive knows the shaft position after a bus drop. IP65 on the body and IP67 at the shaft end means the drive survives washdown and wet environments. The holding brake holds the load when the bus drops — critical for vertical axes where a free-falling Z-axis would crash tooling. ## Mounting and deployment Mounting configurations IM B5 (flange), IM V1 (vertical shaft up), and IM V3 (vertical shaft down) cover most motor-mounting positions. The shaft ships with a fitted key, tolerance N. Natural air cooling means no coolant lines or fan wiring — just the motor power and encoder cables. In a food plant or packaging line, that reduces leak paths and cleaning crevices.","metaTitle":"Siemens 6SL3540-6DF71-0RB2 SINAMICS S120M Servo Drive, 1.3 N","metaDescription":"Siemens 6SL3540-6DF71-0RB2 SINAMICS S120M distributed servo-drive, 1.3 Nm, 3000 RPM, DC 600V input, IP65/IP67, with holding brake.
