Headline ratings and what they drive
The 1FL6064-1AC61-2AB1 is a SIMOTICS S-1FL6 servomotor from the 1FL6 family built to pair with SINAMICS V70/V90 converters — 3AC 400 V operating voltage, rated power 1.5 kW at a nominal speed of 2000 rpm, with a standstill torque M0 of 8 Nm and rated torque MN of 7.16 Nm, shaft height 65 mm (cites:). That M0/MN ratio sits close to 1, which means the motor delivers nearly its full rated torque down to stall — useful where a positioning axis needs holding torque under load without dropping into a gearbox (cites:). An incremental encoder at 2500 increments per revolution sets the position feedback resolution; with the standard 4× evaluation in a SINAMICS drive that lands around 10 000 counts/rev — fine for general positioning, but an axis that needs absolute position after power-loss needs an external reference (cites:). The motor carries a holding brake and ships with an angle plug rather than a straight connector — the plug orientation matters at install because a tight panel cutout can prevent the cable from rotating to its final position (cites:).
Mechanical and environmental envelope
IP65 with the sealing ring fitted means the motor body and connector face tolerate water jets and dust — typical for conveyors, packaging lines, and machine-tool auxiliaries where occasional washdown reaches the motor (cites:). A feather key with tolerance N is the standard shaft interface — when mating to a coupling or gearbox, confirm the keyway depth class against the driven element; a half-key or full-key arrangement on the partner side changes the balancing and runout (cites:).
Lifecycle read: NRND, not yet discontinued
Siemens lists this order code at lifecycle stage NRND — the part is being phased toward end of life but remains available while stock and production transition; new designs should already be looking at the active 1FL6 successor variants (cites:). The internal field still reads 'current', which reflects a lag between the Siemens NRND designation and the catalog system's status flag — treat NRND as the operative answer for production planning (cites:,).
Compliance and export posture
RoHS compliance is declared since 01-01-18 and REACH Art. 33 information is available from the manufacturer — the standard EU environmental package for a Siemens drive component, with no substance-restriction flags raised in this listing (cites:,). ECCN list, which keeps cross-border shipments moving without an EAR filing (cites:). The catalog entry tags the product as class C — manufactured/produced to order, not returnable for credit — so once it ships into a panel it stays in the panel (cites:).
Sourcing posture for an NRND servo
1FL6064-1AC61-2AB1 ships single-piece in a 466 x 264 x 290 mm pack with a 1-piece quantity unit — the box geometry is sized for the 65 mm shaft height frame, not a small parcel (cites:,).
