Sizing the axis around 3.2 Nm continuous
The 1FL2104-4AG01-1MC0 is a SIMOTICS S-1FL2 low-voltage servo motor rated 200 V 3AC, with Pn of 1 kW and M0/Mn of 3.2 Nm at Nn 3000 rpm, on a 40 mm shaft height — squarely a small-format axis motor built to pair with the SINAMICS S200 drive family in the 1FL2 series. Equal M0 and Mn ratings mean the motor delivers its stall torque right up to rated speed with no torque drop-off envelope to derate, so sizing the gearbox and the peak load profile is a 3.2 Nm continuous figure with brief overload margin above it.
Feedback, shaft, and sealing for the cabinet-to-machine run
The feedback stack is the AM21 bit single-turn absolute encoder, with a keyed shaft (tolerance N) and no holding brake — so the holding function has to come from the drive's zero-speed-active logic or a separate brake on the gearbox side, not from the motor itself. The hybrid connector consolidates power and signal into one pluggable interface, cutting cabinet-side gland plate count and panel-side wiring time. Protection class IP65 with oil seal holds against coolant splash and cutting-fluid mist typical on a tool-room spindle feed or parts-handler axis; the seal is the wet-end barrier and demands a face-seated connector to keep the rating.
Match to the SINAMICS S200 and what's on record for compliance
The motor is listed as a matching drive for SINAMICS S200 in the family, so the PROFINET/commissioning path stays inside one validated Siemens pairing rather than mixing servo platforms — the loop tuning profiles and encoder scaling are authored for the S-1FL2/S200 combination.
