Nominal torque is 106.2 lbf.in (12 N.m) on both 24 V and 48 V buses; peak stall torque reaches 218.79 lbf.in (24.72 N.m) on either supply, giving roughly a 2× short-term overload margin above nominal — what governs the sizing decision is the duty cycle around that peak figure, not the larger DC-bus number. Current draw is 5500 mA maximum continuous and 7000 mA peak; the drive tolerates natural-convection cooling, so cabinet airflow design needs to leave clearance around the housing rather than counting on the motor's own thermal dissipation. ## Electrical and network interface Network type is DC with four signals that each direction (input or output) and Ethernet at 10/100 Mbits — this is the Lexium II integrated-drive package, not a standalone servo that needs an external amplifier, so the cabinet-side decision is mounting space and connector reach, not a separate drive chassis. Nominal output power is 54 W on 24 V and 68 W on 48 V; the protection set covers overload of output voltage, short circuit of the output voltage, and safe torque off, so STO is present at the drive level rather than requiring an external relay. ## Mechanical fit on the machine Mounting is flange-style on a 2.6 in (66 mm) motor flange with overall length 6.9 in (174 mm) — when laying out the BOM line, the 174 mm body length plus the keyed shaft at 0.4 in (10 mm) diameter and 0.6 in (16 mm) key dictates the bracket or gearbox mating part. The shaft is single-ended and keyed with no holding brake; no second shaft end is provided. Centring collar depth is 0.2 in (4 mm). ## Compliance and environmental envelope The unit carries CE marking and is qualified to IEC 61800-3 Ed 2 (including EN 61800-3:2001 second environment), EN/IEC 50178, EN 50347, and IEC 60072-1 — for an MRO buyer building a declaration of conformity, those standards are the cited basis on the nameplate. Operating envelope is 15 to 85 % relative humidity without condensation, up to 1000 m altitude without derating, with shock resistance 150 m/s² for 1000 shocks and vibration resistance 20 m/s² from 10 to 500 Hz over 10 cycles per EN/IEC 60068-2 parts 2-29 and 2-6.","metaTitle":"Schneider Electric ILE2T661PB1A4 Servo Motor, 12 N.m","metaDescription":"Schneider Electric ILE2T661PB1A4 Lexium integrated drive servo motor, 12 N.m nominal torque, 115:1 gearbox, CE marked.
