The unit carries CE marking and is designed for pulse/direction control at 24 V or 36 V logic levels, with 6 poles and a rotor inertia of 1.1 kg·cm². This integrated drive accepts pulse/direction signals at 24 V or 36 V to position the motor shaft with an accuracy of ±6 arc minutes. The 2 Nm holding torque suits direct-drive applications where a separate gearbox is omitted — the unit ships without a gearbox and without a holding brake. The motor winding resistance is 20.0 Ω, and the rotor inertia of 1.1 kg·cm² defines the acceleration profile for load matching. Feedback is via an index pulse, adequate for open-loop stepper positioning where encoder resolution is not required. Protection circuits cover overload and short circuit of the output voltage, plus safe torque off (STO) for emergency-stop integration. Natural convection cooling keeps the package compact — no forced air required. ## Applications Lexium integrated drives of this class are used in compact motion axes for packaging, labeling, pick-and-place, and small conveyor indexing where space is tight and a separate drive cabinet is undesirable. The single-phase 36 V DC supply simplifies wiring in distributed machine architectures. Within Schneider's Lexium range the ILS1U851PB1A0 sits in the integrated drive family — a stepper motor with onboard drive electronics, eliminating the cable harness and panel space a separate drive would require. It targets OEM machine builders who need a pre-validated motion subassembly with a single order code. The ILS1U851PB1A0 carries CE marking and is designed to EN 61800-3:2001 for the second environment (industrial power networks). Compliance documentation includes standards EN 60072-1, EN 50347, EN 50178, and IEC 61800-3 Ed 2. The unit is not marked as obsolete in the current catalog; confirm current lead time and minimum order on the RFQ.","metaTitle":"Schneider ILS1U851PB1A0 Lexium Integrated Drive Stepper Motor","metaDescription":"Schneider Lexium integrated drive ILS1U851PB1A0: 3-phase stepper motor, 36 V DC, 6 poles, 2 Nm torque, IP41, CE marked, shock rated 150 m/s².","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Unclassified"],"specifications":{"Phase":"Single phase","Length":"5.5 in (140.6 mm)","Marking":"CE","Category":"US1PC5618288","Shaft end":"Untapped","Standards":"EN 61800-3:2001, second environment IEC 60072-1 EN/IEC 61800-3 EN 50347 EN/IEC 50178 EN 61800-3 : 2001-02 IEC 61800-3, Ed 2","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":"Without","Nominal speed":"200 rpm 24 V 400 rpm 36 V","Rotor inertia":"1.1 kg.cm²","Accuracy error":"+/- 6 arc min","Holding torque":"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","Operating altitude":"<= 3280.84 ft (1000 m) without derating","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...40 V","Associated fuse rating":"10 A","Discrete input current":"10 mA at 24 V safety input","Maximum axial force Fa":"170 N tensile force) 30 N force pressure)","Number of motor stacks":"1","Communication interface":"Pulse/direction 24 V, 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":"2000 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":"1.8°, 0.9°, 0.72°, 0.36°, 0.18°, 0.09°, 0.072°, 0.036° 200, 400, 500, 1000, 2000, 4000, 5000, 10000 steps","[Us] rated supply voltage":"36 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":"122...149 °F (50...65 °C) (with power derating of 2 % per °C) 32...122 °F (0...50 °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":"$914.00 – $1,770.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d2fc00547366d813f3208aeafff84e4c.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/ILS1U851PB1A0/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/ILS1U851PB1A0","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/ILS1U851PB1A0 when reusing this data.
