It carries 6 poles, an integrated Modbus TCP interface, and a holding brake, all within an IP41-rated flange-mount package. The unit is CE marked and complies with EN/IEC 61800-3 for EMC in the second environment, making it suited for industrial machine cabinets where conducted and radiated emissions must be controlled. As a closed-loop stepper system, the ILS2T851PB1F0 uses an index pulse feedback type to maintain position accuracy within ±6 arc minutes, with a rotor inertia of 1.3 kg·cm² that influences acceleration and settling time in point-to-point moves. The integrated drive accepts 48 V DC and Modbus TCP commands at 9.6, 19.2, or 38.4 kbaud over RS485, with four configurable signal lines that can serve as digital inputs or outputs. The holding brake is built in, eliminating the need for an external brake resistor on vertical loads or when power is removed. Protection covers overload and short circuit of the output voltage, plus Safe Torque Off (STO) for controlled stop in safety circuits. Natural convection cooling keeps the design simple, with no fan to fail. ## Applications Lexium integrated drives of this class are specified in packaging, labeling, pick-and-place, and small assembly machines where a compact motor-drive package saves panel space and wiring. The 48 V DC supply suits battery-backed or low-voltage environments, and the Modbus TCP interface integrates directly with PLCs and HMIs without a separate motion controller. The ILS2T851PB1F0 carries CE marking and complies with EN/IEC 50178, IEC 60072-1, EN 61800-3:2001, and EN 50347. No lifecycle status (active, NRND, or discontinued) is listed in the available evidence; an RFQ is the recommended path to confirm current production status and lead time.","metaTitle":"Schneider ILS2T851PB1F0 Lexium Integrated Drive, 48 V, 2 Nm, 6-Pole","metaDescription":"Schneider Lexium ILS2T851PB1F0 integrated stepper drive: 48 V DC, 2 Nm torque, 6-pole, Modbus TCP, IP41, CE marked, 150 m/s² shock rated.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Unclassified"],"specifications":{"Phase":"Single phase","Length":"7.4 in (187.3 mm)","Marking":"CE","Category":"US1PC5618288","Shaft end":"Untapped","Standards":"EN/IEC 50178 IEC 60072-1 EN 61800-3:2001, second environment EN 61800-3 : 2001-02 IEC 61800-3, Ed 2 EN 50347 EN/IEC 61800-3","Motor Type":"3-phase stepper motor","Network type":"DC","Second shaft":"Without second shaft end","Shaft length":"1.2 in (30 mm)","Winding type":"Medium speed of rotation and medium torque","Feedback type":"Index pulse","Gear box type":"Without","Holding brake":"With","Nominal speed":"300 rpm 24 V 600 rpm 48 V","Rotor inertia":"1.3 kg.cm²","Accuracy error":"+/- 6 arc min","Holding torque":"53.1 lbf.in (6 N.m) holding brake 17.7 lbf.in (2 N.m)","Nominal torque":"17.7 lbf.in (2 N.m)","Shaft diameter":"0.5 in (12 mm)","Protection Type":"Overload of output voltage Short circuit of the output voltage Safe torque off","Type of cooling":"Natural convection","lifecycle_stage":"current","Mounting Support":"Flange","Range of Product":"Lexium integrated drive","Shock resistance":"150 m/s² 1000 shocks EN/IEC 60068-2-29","Device short name":"ILS","Input/output type":"4 signals (each be used as input or output)","Motor flange size":"3.3 in (85 mm)","Peak stall torque":"17.7 lbf.in (2 N.m)","Relative humidity":"15...85 % without condensation","Transmission Rate":"10, 100 Mbits","Brake release time":"40 ms","Operating altitude":"<= 3280.84 ft (1000 m) without derating","Brake pull-in power":"22 W","Current consumption":"5000 mA maximum continuous","Vibration resistance":"20 m/s² 10...500 Hz) 10 cycles EN/IEC 60068-2-6","Centring collar depth":"0.08 in (2 mm)","Electrical Connection":"Printed circuit board connector","Nbr. of units in pkg.":"1","Number of motor poles":"6","Service life in hours":"20000 h bearing","Supply voltage limits":"18...55 V","Associated fuse rating":"16 A","Brake application time":"20 ms","Discrete input current":"10 mA at 24 V safety input 2 mA at 24 V 24 V signal interface","Maximum axial force Fa":"170 N tensile force) 30 N force pressure)","Number of motor stacks":"1","Commissioning interface":"RS485 Modbus TCP 9.6, 19.2 and 38.4 kbauds)","Communication interface":"Modbus TCP, Integrated","Continuous stall torque":"17.7 lbf.in (2 N.m)","Discrete output voltage":"23...25 V","IP degree of protection":"IP41 shaft bushing: conforming to EN/IEC 60034-5 IP54 total except shaft bushing: conforming to EN/IEC 60034-5","Maximum radial force Fr":"100 N","Mounting holes diameter":"0.3 in (6.5 mm)","Centring collar diameter":"2.4 in (60 mm)","Maximum mechanical speed":"3000 rpm","Number of mounting holes":"4","Maximum switching current":"100 mA per output 200 mA total","Product or Component Type":"Motion integrated drive","Speed feedback resolution":"20000 points/turn","[Us] rated supply voltage":"48 V 24 V","Voltage state 0 guaranteed":"-3...4.5 V","Voltage state 1 guaranteed":"15...30 V","Ambient Air Temperature for Storage":"-13...158 °F (-25...70 °C)","Ambient air temperature for operation":"104...131 °F (40...55 °C) (with power derating of 2 % per °C) 32...104 °F (0...40 °C) (without derating)","Circle diameter of the mounting holes":"3.9 in (99 mm)","Permissible ambient air temperature around the device":"221 °F (105 °C) power amplifier 230 °F (110 °C) motor"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2,177.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/5ced8d9bb8b7e427a7e1acda5747d244.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/ILS2T851PB1F0/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/ILS2T851PB1F0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/ILS2T851PB1F0 when reusing this data.
