Footprint, shaft, and how it bolts onto the machine
The ILA2T571TB2A0 ships as a 7.5 in (189.3 mm) long AC synchronous servo with a 2.2 in (57 mm) flange face, an untapped 0.4 in (9 mm) shaft that protrudes 0.8 in (20 mm), and a 0.06 in (1.6 mm) centring collar — a compact footprint for the Lexium integrated drive line that bolts straight onto the gearbox or pinion carrier without an extra coupling adaptor.
What the electrical envelope actually means on the bench
It is a single-phase DC bus device with 18–55.2 V supply limits, and the winding is the high-speed / medium-torque variant — nominal speed 5000 rpm at 24 V or 7000 rpm at 48 V, so the 48 V rail is the one to spec when the line needs the upper rev band. Continuous current draw tops out at 7500 mA with 11000 mA peak, and the natural-convection cooling means no fan filter to clean on a washdown line — the motor relies on its housing surface and the machine's airflow to dump heat. Feedback is a multi-turn encoder with ±0.05° accuracy error, and the integrated drive exposes 4 signals usable as input or output for end-of-travel, home, or enable wiring without dropping in a separate I/O brick.
Built-in protection and the standards it ships under
Protection covers output overvoltage, short-circuit of the output stage, and safe torque off — STO is wired into the drive rather than relying on the upstream contactor, which simplifies the safety circuit on a guarding retrofit. The unit carries CE marking and is qualified to EN/IEC 50178, IEC 61800-3 (Ed 2), IEC 60072-1, EN 50347, and EN 61800-3:2001 second environment — that second-environment EMC classification is the figure that matters when the drive is mounted inside an industrial cabinet rather than on the open factory floor.
Mechanical life and the duty the bearings will take
Shock rating is 150 m/s² for 1000 shocks and vibration is 20 m/s² across 10–500 Hz per EN/IEC 60068-2-6/29, with a 20000 h bearing service life — the figure to budget against when sizing a preventive-replacement interval on a high-cycle axis. Operating altitude is ≤1000 m without derating and humidity is 15–85 % non-condensing, so sealed enclosures are needed for outdoor or refrigerated deployments above that ceiling.
