Siemens 1FL6042-1AF61-2AA1 SIMOTICS S-1FL6 0.4kW 3000rpm 400V IP65 Servo Motor

The Siemens 1FL6042-1AF61-2AA1 is a SIMOTICS S-1FL6 servo motor rated 0.4 kW at 3000 rpm on a 3 AC 400 V supply, with 1.27 Nm rated torque and 1.9 Nm standstill torque. Shaft height is 45 mm with a 2500 signal/rev incremental encoder and feather key, no holding brake, IP65 protection with a sealing ring. It is compatible with SINAMICS V70 and V90 converters.

Selection Notes

At shaft height 45 mm and 3000 rpm rated speed, this 1FL6 motor pairs with the SINAMICS V90 or V70 converter family, so confirm the converter's rated power matches this motor's 0.40 kW rating for correct current-loop tuning. The 3.80 Nm maximum torque against a 1.27 Nm rated torque gives roughly 3x momentary overload headroom for acceleration and quick-stop events. No holding brake is fitted, so vertical-axis or gravity-loaded applications need an external brake.

Applications

Suited to compact single-axis positioning tasks such as pick-and-place, indexing tables, and small conveyor drives run from a SINAMICS V70 or V90 servo converter, in wash-down or dusty environments where the IP65 sealing ring matters.
