The Siemens 6SL3563-6DF71-0RG1 is a SINAMICS S120M distributed servo-drive in the AH63 frame size, rated for 7.1 Nm standstill torque and 3000 RPM nominal speed. It runs on a DC 600V intermediate circuit and carries a 20-bit absolute encoder for position feedback. The IP65 rating means the housing and shaft seal withstand washdown environments — this drive mounts directly on the machine frame, not in a cabinet, so it suits food-and-bev or wet-floor lines where a central drive cabinet would be impractical.
What the ratings mean for fit
The 7.1 Nm standstill torque and 3000 RPM define the mechanical envelope: this drive handles a direct-coupled load up to roughly 2.2 kW at rated speed. The DC 600V input ties it to a SINAMICS S120 common DC bus or a regulated supply — it is not a standalone AC-fed drive. The 20-bit absolute encoder gives 1,048,576 counts per revolution, enough for high-resolution positioning without a homing cycle on power-up. Natural air cooling and the IP65 enclosure mean no fan filter changes and no cabinet ventilation slot — just verify ambient temperature stays within the drive's rated range.
Mounting and integration
The drive supports IM B5 (flange-mounted with through-hole), IM V1 (shaft-down vertical), and IM V3 (shaft-up vertical) mounting orientations, so it adapts to the machine's mechanical layout. The plain shaft without holding brake means the load must be self-locking or braked externally — factor that into the axis design if vertical loads are present. The 20-bit encoder cable and DC power feed both need shielded, IP65-rated connectors; the DRIVE-CLiQ interface handles communication back to the S120 control unit.
