Where it sits in the cabinet
The 1FK2104-5AF00-1MB0: The Siemens 1FK2 series servo drops into a SINAMICS S120 line — a 0.75 kW continuous rating at 3000 rpm on a 380-480 V bus drops to 0.375 kW at 1500 rpm when run on a 200-240 V bus, so the same motor can be paired with both 400 V-class and 230 V-class drive line-ups without a mechanical change. Holding torque M0 is 2.4 Nm on this frame, and the absolute encoder AM22DQC reads 22-bit single-turn plus 12-bit multiturn over the DRIVE-CLiQ link — that resolution is what gives the velocity loop the headroom to push a high-inertia load without the scope catching cogging steps at low speed.
Encoder feedback and the loop it enables
Encoder AM22DQC at 22-bit + 12-bit multiturn means roughly 4 million counts per revolution on the position channel and 4096 turns of absolute range — for a pick-and-place axis that never loses its home position through a power cycle, the absolute bits remove the homing routine on every cold start. DRIVE-CLiQ is the Siemens-native digital encoder interface — the motor and drive negotiate the resolver/encoder protocol over a single M17 cable, so a field swap does not require encoder-parameter re-entry in the drive project.
Shaft, housing, panel fit
Shaft is D19 x 40 mm with a feather key, and the body sealing is IP64 — adequate for an enclosed cabinet or a gantry inside an IP-rated machine skin, but this is not the washdown-rated HP version of the 1FK2 line, so food-and-bev or outdoor exposed mounting needs an up-rate review. Power connector is M17 size, matching the DRIVE-CLiQ plug — the pair carries both motor power and feedback on M17 housings, which keeps the cable gland count to two per axis on the cabinet wall.
Lifecycle and sourcing posture
The product is built to order under class C, packed 1 piece per shipper at 452 x 250 x 267 mm — quoting volume into an RFQ gives the lead-time envelope the manufacturer will honor against the BOM quantity.
