Where this motor drops into the cabinet
The Siemens 1FL6066-1AC61-2AB1 is a SIMOTICS S-1FL6 low-inertia servomotor from the 1FL6 family, built specifically for SINAMICS V70 and V90 servo converters, and the 65 mm shaft height together with the TTL 2500 incr/rev incremental encoder and feather key confirms it as a direct panel-mount servo load for those drive families. Operating voltage is 400 V 3AC with PN of 1.75 kW at a rated speed NN of 2000 rpm, peak stall torque M0 of 11 Nm, and rated torque MN of 8.36 Nm — the headroom from M0 to MN is small, so sizing has to be done on the continuous torque axis, not the headline stall figure.
Mechanical stack — brake, encoder, sealing
The motor ships with a holding brake, a feather key on the shaft, and an IP65 sealing ring at the housing face, so the assembly is sized for machinery-duty cabinets and plant-side mounting where shaft spray and dust are a concern. Encoder feedback is incremental TTL at 2500 increments per revolution — adequate for V90 position-mode commissioning without the wiring overhead of a multi-turn absolute bus, and kept inside the converter's standard commissioning profile.
Lifecycle read on this code
The factory records this order code as NRND — not yet discontinued, but flagged for phase-out, which is the lifecycle state that decides whether a buyer commits new design, sources a spare for a running line, or starts qualifying a successor now. Product class C applies: this motor is built per order, not held as returnable shelf stock, and confirmation of quantity availability runs through the RFQ against the current production slot.
Administrative codes on this line
Internal handling codes on the Siemens line: Group Code R220 and Product Group 5183, which are the catalogue-side keys a buyer uses to confirm the MPN maps to the intended servomotor family at the order-entry desk. Single-piece pack dimensions are 466 x 264 x 290 mm, which matters for the receiving dock's crate slot rather than for selection.
