Motor specs and what they mean for the cell
The 1FL6061-1AC61-0LH1 is a SIMOTICS S-1FL6 servo motor from Siemens, delivering 0.75 kW at 2000 rpm rated speed with a continuous torque of 3.58 Nm and a standstill torque of 4 Nm. That torque at zero speed means it holds position without needing the brake during normal operation — the holding brake is there for the powered-down state or an E-stop, not for every cycle stop. The absolute encoder is 20-bit multi-turn with 12-bit resolution, giving 1,048,576 positions per revolution and tracking up to 4096 revolutions from power-on. No homing routine needed after a power cycle — the controller reads the position directly, which shaves time off the startup sequence in a multi-axis cell.
Shaft height is 65 mm with a plain shaft and tolerance N, meaning it fits standard metric couplings and pulleys without a keyway — the clamping force from the coupling hub holds the torque. The IP65 rating with sealing ring means the motor body and shaft seal resist washdown and coolant spray, so it can sit directly on a machining center or packaging line without a cover boot. Compatible with SINAMICS V70 and V90 drives — the motor feedback interface matches those drive families directly, so no adapter cable or external encoder converter is needed. The holding brake is 24 VDC, released when power is applied; the drive handles the brake control through its standard motor cable.
