Commissioning fit — torque, encoder, and IP65
The 1FL6066-1AC61-0LG1 is a SIMOTICS S-1FL6 servo motor rated at 1.75 kW with a rated speed of 2000 rpm, a stall torque M0 of 11 Nm, and a rated torque MN of 8.36 Nm. This torque profile suits direct-drive or low-backlash gearing on indexing, winding, and pick-and-place axes where the load torque at speed stays within the continuous MN band and peak acceleration draws from the M0 margin. The 20-bit absolute encoder (12-bit multi-turn) eliminates the need for a homing cycle on power-up — the axis position is retained across a bus voltage loss, provided the backup battery on the SINAMICS V70 or V90 drive is maintained. This is critical for a GMP line where a lost position reference after a power cycle would require re-qualification of the axis travel limits. The sealing ring must be seated correctly at installation to maintain the IP65 rating; the gland plate entry for the motor cable also needs a matching IP65-rated fitting.
Sourcing and lifecycle — active, traceable, quoted to order
The motor is a spare part within the SIMOTICS S-1FL6 family, designed for direct compatibility with SINAMICS V70 and V90 drive converters. For a BOM freeze or a controlled change in a validated line, this part is qualifiable and traceable — the nameplate data supports the audit trail from PO to installed unit.
