Sizing the ILA for a 24/48 VDC motion axis
The ILA2T571TB1A0 is the AC synchronous servo member of the Schneider Lexium integrated drive line (ILA short name, Lexium integrated drive range), built around a 57 mm flange and a single-turn encoder for commutation feedback. It draws 7500 mA maximum continuous and peaks at 11000 mA, which fixes the DC-bus sizing: at 24 V the nominal speed is 5000 rpm and climbs to 7000 rpm at 48 V — pick the supply rail first, then the motion profile.
Mechanical fit and shaft interface
Mounting is flange-supported with a 57 mm motor flange, and the shaft end is untapped — couplings or mounted elements need a clamping-hub style fastening rather than a setscrew on the shaft thread. Shaft diameter is 9 mm with a 20 mm shaft length, and the centring collar depth is 1.6 mm — verify the mating pulley or pinion bore and keyway before committing the BOM line. Body length is 145.3 mm, so the cut-out and clearance for the gear-side accessory must accommodate the short-block footprint of the ILA family.
I/O, feedback, and what the drive tells you
Feedback is a single-turn encoder — sufficient for absolute position within one revolution, which simplifies homing on power-up but is not a multi-turn replacement; confirm the application does not require retained position across power cycles. Four signals are available as input or output, so the same physical pin serves either role depending on configuration — plan the wiring diagram with the four-channel budget, not against a fixed direction. Network type is DC and electrical connection is via a printed circuit board connector — the drive is intended to drop onto a mating PCB rather than accept discrete cabling on the motor housing.
Protective functions and ambient envelope
Protection covers output voltage overload, safe torque off, and output short circuit — safe torque off is the functional stop the integrator relies on for guard-door release, not just an overcurrent trip. Cooling is natural convection — no fan to fail in service, but the rated torque holds only if the housing sees unobstructed airflow; inside a sealed cabinet the derating curve on the product drawing applies. Operating altitude is 1000 m without derating, relative humidity 15 to 85 percent non-condensing, vibration resistance 20 m/s² across 10 to 500 Hz, and shock resistance 150 m/s² for 1000 shocks — within the IEC 60068-2 envelope for industrial panels. Bearing service life is rated at 20000 h — the L10 figure rather than an MTBF figure, and is the limit that drives preventive replacement on high-cycle lines.
Standards the integrator has to clear
The ILA2T571TB1A0 is marked CE and listed against IEC 60072-1 for mounting dimensions, EN/IEC 61800-3 for EMC in the second environment, EN 50347 for motor dimensions, and EN/IEC 50178 for power drive systems — the standards the panel builder certifies against rather than a regional UL file. Note the absence of an explicit UL listing in this evidence bundle — for North American UL 508A panel builds, confirm acceptance through the local inspector rather than assuming the CE mark transfers.
Ordering posture for this line
For a tail-spend consolidator, the right play is to put this order code on the preferred-supplier punch-out so the next PO is one-click rather than a one-off requisition — same quoted-to-order economics, lower cost per PO.
