Motor specs that drive the selection
The Siemens 1FL6067-1AC61-0LB1 is a SIMOTICS S-1FL6 servo motor rated at 2 kW continuous power with a rated speed of 2000 rpm and a rated torque of 9.55 Nm. The stall torque (M0) is 15 Nm, giving you headroom for acceleration and overload without exceeding thermal limits. It runs on a 400 V three-phase AC supply and is explicitly listed as compatible with SINAMICS V70 and V90 drives — no adapter cables or firmware hacks needed.
Encoder and feedback — absolute, no homing cycle needed
The 20-bit absolute encoder (12-bit multi-turn) means the drive knows the rotor position and the number of shaft revolutions at power-up. On a multi-axis line, this eliminates the homing sequence after every power cycle — a time saver on machines that cycle power for tool changes or shift starts. The encoder resolution (20-bit = 1,048,576 counts per revolution) gives fine position granularity for applications like pick-and-place or contouring where step loss is unacceptable.
Mechanical fit — shaft height, key, brake, and IP65
Shaft height is 65 mm with a feather key and tolerance N — this matches the standard NEMA or IEC mounting footprint for that frame size. The holding brake is integrated, so the motor holds position on a vertical axis without a separate brake resistor or external brake module. IP65 with the supplied sealing ring means the motor body and the shaft seal withstand washdown — suitable for food-and-bev lines or coolant-splash environments. The sealing ring must be seated between the motor flange and the mating gearbox or machine face; without it the IP rating drops.
