What does the 1FL2104 drop onto an existing axis?
The 1FL2104-2BF01-0MC0 is a SIMOTICS S-1FL2 low-inertia servo in the 40 mm shaft-height frame, with a rated shaft power of 0.75 kW at 3000 rpm and matched standstill and rated torque of 2.4 Nm — so a retrofit holding the original gearbox ratio keeps the mechanical envelope intact while pulling in the newer SINAMICS S200 drive electronics. Supply voltage is 400 V 3AC; feedback is the 21-bit AM encoder carried over a single hybrid cable, which is the configuration the matching SINAMICS S200 expects out of the box — no resolver interface board or external terminal box to wire in.
Mechanical envelope and where it actually mounts
Shaft height 40 mm, plain shaft with tolerance N, no holding brake — meaning the holding function has to come from the drive's ramp-down profile or a downstream mechanical brake; if the old axis had a brake-equipped servo, the brake-coil wiring and the brake-rail connector are not on this code. Protection class IP65 with oil seal on the shaft end, so the motor takes washdown and cutting-fluid splash typical of small packaging and pick-and-place cells; the connector face itself stays dry because the seal is at the shaft, not at the housing thread.
Sourcing posture and lifecycle read
Lifecycle is current and the product class is built-to-order — returns are not creditable and the unit ships from the configured BOM line, so a BOM freeze needs the exact configuration suffix committed before the order is opened. RoHS compliance is in force since 01-01-18 and REACH Art. 33 information is published, which is the baseline paperwork an EU ship-to now expects on the shipping documents; export-control classification is AL:N / ECCN:N, so no dual-use export licence is in the path for typical commercial destinations. Packaging is a single piece in a 315 x 182 x 172 mm box — relevant when a panel builder is kitting a retrofit one motor at a time rather than a batch, because the carton footprint drives the inbound goods bench space.
