What is on the nameplate is a SIMOTICS S 1FK7-CT synchronous servo motor: PN=0.47 kW, UDC=300V, M0=1.6Nm at the 100K winding, NN=3000rpm, naturally cooled — a compact low-inertia frame sized for high-dynamic positioning on a SINAMICS S120 drive line rather than for continuous-torque duty. ## Reading the ratings against the application PN=0.47 kW and NN=3000rpm put this frame in the small-format pick-and-place / indexing / small-axis servo bracket — the rated speed sits well above what a 4-pole induction motor would deliver at 50/60 Hz, which is exactly why the drive side is a SINAMICS S120 (or comparable) with a regulated DC bus, not a plain V/Hz drive. UDC=300V means the motor is wound for a 300 V DC link, matching the rectifier output of a 230 V-class SINAMICS line; pairing it with a 400 V-class drive pushes the field-weakening corner in and shortens the constant-power range, so the drive commissioning parameters need to be re-checked against the actual bus voltage on the cabinet. M0=1.6Nm at the 100K temperature class and natural cooling (no fan on the motor) means the continuous torque rating is the standstill figure derated for the surface-mounted housing — in a sealed cabinet the thermal headroom shrinks fast, so ambient and mounting plate temperature are the real sizing inputs, not the catalog M0 number alone. ## Sourcing posture on a hot EOL line For a controls engineer staring at a midnight startup, the practical question is whether the spare on the shelf decodes to the same winding and encoder option as the one being swapped — the dashed suffix on 1FK7034-2AF2.-.... carries the encoder / shaft / holding-brake options, so the replacement order code has to match the full string, not just the base. ## What to confirm before commissioning the replacement On the drive side the motor's encoder resolution and order code suffix drive the auto-configuration in STARTER / SINAMICS StartDrive — a 1FK7 with an absolute encoder and a 1FK7 with an incremental encoder do not commission from the same drive parameter set, and the wrong selection is the most common reason a 'good' motor throws a fault on first power-up.","metaTitle":"Siemens 1FK7034-2AF2.-....
