Drive selection memo
The Siemens 6SL3562-6DF71-0RG1 is a SINAMICS S120M distributed servo-drive in an AH63 frame size, rated for 5 Nm continuous torque at 3000 RPM rated speed. It runs on a DC 600 V input bus — typical for the S120M family's shared DC-link architecture — and carries a 20-bit absolute encoder for position feedback without a separate encoder cable run. Natural air cooling keeps the enclosure simple; the IP65 rating means the drive body and shaft seal withstand washdown, so it mounts directly on a machine frame or gearbox in food, packaging, or material-handling lines without a separate cabinet.
What the ratings mean for fit
The 5 Nm torque rating is the continuous stall torque at rated speed — sized for a moderate inertial load like a small indexing table or a pick-and-place axis. The 3000 RPM top speed suits most direct-drive or low-ratio applications; if your axis needs higher speed, you would step up to a smaller frame or a gearbox. The 20-bit absolute encoder gives 1,048,576 counts per revolution, enough for precise positioning without a homing cycle on power-up — a real time-saver on multi-axis lines. The plain shaft (no holding brake) means the load must self-lock or be held by the motor's own detent torque when power is off; if your vertical axis needs a brake, this variant is not the one.
Mounting and integration
The AH63 frame mounts directly to the machine via the IM B5, IM V1, or IM V3 flange patterns listed in the description — no separate motor adapter needed. The IP65 enclosure means the drive lives on the machine, not in a panel; run the DC bus and encoder cables through a suitable IP65-rated gland plate. Natural air cooling requires clearance around the fins — check the SINAMICS S120M manual for minimum free space (typically 50 mm on each side). The 20-bit absolute encoder uses Siemens DRIVE-CLiQ protocol; verify your controller has a compatible DRIVE-CLiQ port.
