Sizing the 1FL6 against the SINAMICS V90 axis
The 1FL6092-1AC61-2LB1 is the SIMOTICS S-1FL6 servomotor in the 1FL6 family, rated 3.5 kW at 2000 rpm with a standstill torque of 22 Nm and a continuous rated torque of 16.7 Nm on a 90 mm shaft-height frame, terminated with an angle plug and a 20-bit absolute encoder (12-bit multi-turn) with feather key and integrated holding brake. It is paired specifically with the SINAMICS V70 and V90 converters, so the drive-side commissioning profile, encoder resolution, and brake control all assume that controller — a 1FL6 on a different drive family will need the equivalent variant code matched to that platform.
What IP65 and the holding brake mean in the cabinet
IP65 with the sealing ring is the sealing class of the motor body — it tolerates dust and low-pressure water jets, which puts it on the candidate list for food-and-bevery lines, machine-tool enclosures, and any washdown-adjacent cell where the cabinet itself is sealed. The integrated holding brake holds the axis at zero speed when the drive is de-energised; sizing it correctly means matching the brake torque against the load's holding requirement (vertical axes especially), not against the motor's continuous torque.
Lifecycle status — what NRND means for the BOM line
The listed product status is NRND (Not Recommended for New Designs), paired with a of current; new machine designs should be steered to the active 1FL6 successor variant where the same shaft height and encoder option exist, while existing fleets continue to be supported for spares and replacement.
Order quantities and the carton that ships
The product class is C — manufactured/produced to order, non-returnable — so the unit ships as 1 Piece per Quantity Unit with packaging dimensions 495.00 x 365.00 x 340.00 mm; production quantities are quoted against the BOM and lead time is confirmed at RFQ.
