The 1FK7 family is the compact high-dynamics line typically paired with SINAMICS S120 drives for positioning axes in machine tools, packaging lines, and assembly automation — applications where the 600 V DC link bus is the standard drive rail. ## Reading the headline ratings PN = 0.94 kW is the rated mechanical output at the continuous duty point, the number the sizing tool uses to confirm the motor carries the load through the duty cycle without thermal trip. UDC = 600 V ties this motor to a SINAMICS S120 line-module / motor-module pair on a 600 V DC bus — a 400 V class drive will not commutate it correctly, and the DC link voltage must be matched at commissioning. M0 = 3 Nm is the standstill torque at the 100 K winding-temperature rise class, which is the figure to use when sizing accel/decel torque margins during the commissioning profile check. NN = 6000 rpm is the rated speed; field-weakening range above this is limited by the inverter and resolver/encoder feedback rather than the mechanical rotor limit. Naturally cooled means no fan on the motor — the rated output assumes the surface convection in the panel; a sealed cabinet derates the continuous figure. ## Lifecycle status — what eol_hot means for your BOM The 1FK7042-2AK7.-.... is flagged eol_hot on the Siemens Servo Motors line. For a buyer, that translates to no fresh factory orders against this order code — the supply path is the independent distribution channel, and availability is lot-specific and confirmed per RFQ. ## Sourcing posture and ordering For line-down spares, lead time and quantity depend on the available inventory at the moment of the request; standing orders or blanket call-offs can be set up once a reliable channel is identified.","metaTitle":"Siemens 1FK7042-2AK7.-....
