Motor ratings and what they mean for the axis
The 1FL2306-4AC11-0MB0 is a SIMOTICS S-1FL2 servo motor rated 1.5 kW at 400 V 3AC supply, delivering 2000 rpm rated speed and 7.16 Nm continuous torque — the M0 holding torque of 8 Nm means the brake holds the load at standstill without power to the windings, which matters for vertical-axis applications where the load must not drift when the drive is off. Shaft height is 65 mm with a plain shaft (no keyway), tolerance N, and the motor carries an AM21bit absolute encoder with angular connector — the 21-bit resolution gives 2,097,152 positions per revolution, enough for positioning accuracy down to arc-seconds on a direct-drive axis without a gearbox.
Drive pairing and integration
This motor is designed to pair with the SINAMICS S200 drive family — the AM21bit encoder interface and the 400 V winding match the S200's feedback and power stage, so the commissioning engineer sets the motor ID data from the drive's parameter list rather than entering custom values. IP65 with oil seal means the motor body and the shaft seal withstand washdown and cutting-fluid splash — the connector end is the wet-end barrier, not the housing thread, so the mating cable connector must also be IP-rated to maintain the seal. The holding brake is integrated — it engages when the drive enable drops, so the MRO planner does not need a separate brake rectifier or external holding circuit; the brake wiring runs through the motor connector.
Compliance and documentation
RoHS compliant since 01-01-18, with REACH candidate-list information available — the quality-doc controller can pull the declaration from the Siemens Industry Online Support portal using the motor's MLFB. Export control is AL: N / ECCN: N — no special license required for cross-border shipment under current regulations.
