It carries an IP41 enclosure, a holding brake, and Modbus TCP communication via RS485 at 9.6, 19.2, or 38.4 kbaud. CE marked, it integrates protection against safe torque off, short circuit, and output overload. This unit packages a 3-phase stepper motor and its drive electronics into a single flange-mounted assembly, eliminating separate cabling and panel space for a drive module. The 2 N.m holding torque (17.7 lbf.in) positions loads at rest without power to the brake, while the ±6 arc-min accuracy suits indexing and pick-and-place cycles where repeatability matters more than sub-arc-minute precision. Rotor inertia of 1.3 kg.cm² keeps acceleration responsive for short-stroke moves. Modbus TCP on the RS485 port handles setpoint and status exchange at 9.6, 19.2, or 38.4 kbaud; the four configurable I/O signals can serve as inputs or outputs for home sensors, enable lines, or fault resets. The holding brake engages on power loss, holding the shaft without external spring-set brakes. Protection includes safe torque off, output short-circuit, and output overload — all monitored internally. ## Compliance & environmental The ILS2T851PC1F0 carries CE marking and complies with EN 50347, EN/IEC 50178, and EN 61800-3:2001 (second environment) as well as IEC 61800-3 Ed. 2 and IEC 60072-1. It is rated for operation up to 3280.84 m altitude and 15 % maximum humidity, with an IP41 enclosure suitable for clean, dry cabinet environments. Shock rating is 150 m/s² over 1000 shocks per EN/IEC 60068-2-29. Within Schneider's Lexium integrated drive family, the ILS2T851PC1F0 fills the single-phase, medium-speed, medium-torque segment — a compact stepper solution for OEM machines that need a holding brake and Modbus TCP connectivity without a separate drive cabinet. It competes with other integrated steppers in the 2 N.m class but distinguishes itself via the 6-pole motor design and the built-in brake, reducing external component count. ## Pricing & sourcing Multi-source data provides a budget estimate for the ILS2T851PC1F0; confirm via RFQ.","metaTitle":"Schneider ILS2T851PC1F0 Lexium Integrated Stepper Drive, 24 V DC, Modbus TCP","metaDescription":"Schneider ILS2T851PC1F0 Lexium integrated stepper motor drive: 6-pole, single-phase, 22 W, 2 N.m torque, IP41, Modbus TCP, holding brake, CE marked.","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 50347 EN/IEC 50178 EN 61800-3:2001, second environment IEC 61800-3, Ed 2 EN 61800-3 : 2001-02 EN/IEC 61800-3 IEC 60072-1","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":"Safe torque off Short circuit of the output voltage Overload of output voltage","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":"Industrial 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":"24 V 48 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":"$2,305.00 – $3,230.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d6bab6cdc999d41a07c73e45ef8e3553.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/ILS2T851PC1F0/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/ILS2T851PC1F0","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/ILS2T851PC1F0 when reusing this data.
