Lexium ILA integrated drive, sized for small-motion loads
The ILA2T571TC2A0 is the ILA device short name from the Lexium integrated drive range — an AC synchronous servo motor with the drive electronics packaged onto the motor, not a separate cabinet module, which is what cuts the panel footprint for short-cable, low-axis machines. It is wound for high rotational speed and medium torque (cite:), with a 57 mm motor flange and an overall length of 7.5 in (189.3 mm) (cite:) (cite:), and ships without a holding brake (cite:) — a fact that matters at commissioning because any vertical-axis application has to be re-evaluated against an external brake or gravity-loaded gear train.
DC bus, current draw, and what to budget at power-up
The unit is DC-fed through an industrial connector (cite:) with supply limits of 18 to 55.2 V (cite:) — the wider window lets the same SKU ride a 24 V machine bus or a 48 V motion bus. Peak current draw is 11000 mA, with a maximum continuous of 7500 mA (cite:), which is the figure the upstream PSU and fusing have to clear, not the nominal rating. Built-in protections cover overload on the output voltage, short circuit of the output voltage, and safe torque off (cite:), so the drive stops cleanly on a commanded STO event without needing a separate safety contactor upstream of the bus — important at handover when the safety circuit is being walked through. Four signals, each usable as input or output (cite:), carry the local I/O without an expansion module, and 10/100 Mbit comms (cite:) cover the fieldbus side.
Mechanical interface and feedback
Flange mounting with a 9 mm shaft and 20 mm shaft length (cite:) (cite:) suits the standard small-footprint coupling-and-bracket pattern — no tapped shaft end (cite:), so a keyed or clamped hub is the way to take torque off. The centring collar depth is 1.6 mm (cite:), which dictates how far the mating face sits back from the motor pilot. Position feedback is a multiturn encoder (cite:), so absolute position survives a power cycle without a homing routine — fewer gotchas at restart, fewer reasons to spend a Saturday on site because the machine forgot where it was. Bearing service life is rated 20000 h (cite:), which is the maintenance interval the MRO planner should be tracking on a multi-shift line.
Environmental envelope and the standards on file
Cooling is natural convection (cite:), so the drive must be mounted on a thermally conductive surface or with clear airspace around the housing — no fan to fail, but also no margin for stacking tightly in a sealed cabinet. Compliance is recorded against IEC 61800-3 Ed 2, EN/IEC 61800-3, IEC 60072-1, EN 50347, EN/IEC 50178, and EN 61800-3:2001 second environment (cite:), with CE marking (cite:). That second-environment classification under EN 61800-3:2001 is what allows the drive in light-industrial installations without the heavier filter set a first-environment EMC requirement would impose.
