It operates on a 400 V three-phase AC supply and integrates a 20-bit absolute encoder with a feather key on the shaft, plus a holding brake for vertical-axis holding. The IP65 degree of protection, achieved with the included sealing ring, makes it suitable for washdown environments in food-and-bev or machine-tool lines where coolant spray is present. ## SINAMICS V70/V90 drive pairing This motor is explicitly listed as compatible with SINAMICS V70 and V90 converters, meaning the encoder interface and motor feedback loop are pre-configured for those drive families without additional adapter hardware. The shaft height of 90 mm and the feather key tolerance define the mechanical interface for coupling to the load — confirm the mating half's bore and keyway dimensions before committing the BOM line.","metaTitle":"Siemens 1FL6090-1AC61-0LB1 SIMOTICS S-1FL6 Servo Motor","metaDescription":"Siemens SIMOTICS S-1FL6 servo motor, 2.5 kW, 2000 rpm, 11.9 Nm, IP65, 20-bit absolute encoder, holding brake.
