The Siemens 6SL3563-6DF71-0RB2 is a SINAMICS S120M distributed servo-drive in the AH63 frame size. It delivers 7.1 Nm rated torque at 3000 rpm from a DC 600V input, with a 20-bit absolute encoder for position feedback. The motor end is rated IP65, the shaft end IP67, making it suitable for washdown or dusty environments. An integrated holding brake holds the load at standstill without power.
What the ratings mean for fit
The 7.1 Nm rating is the continuous stall torque at rated speed — enough for indexing tables, small conveyors, or pick-and-place axes up to that load. The 3000 rpm top speed suits moderate-speed positioning; if your application needs higher speed, this frame may not be the right choice. The DC 600V input ties to a common DC bus in S120M systems — verify your bus voltage matches before specifying.
Deployment context
The IP65 body and IP67 shaft end allow direct mounting on a machine frame without an additional enclosure, even in areas exposed to coolant splash or washdown. The holding brake (spring-applied, power-off) keeps the load safe during power loss — important for vertical axes or any application where coasting is unacceptable.
