Schneider Electric ILS1B853S1456 – Integrated NEMA 34 Stepper for Compact, Precise Motion

The Schneider Electric ILS1B853S1456 sits in the Lexium ILS family of integrated steppers. It combines a high‑torque 85 mm (NEMA 34) stepper motor with a built‑in drive, so you cut panel wiring, simplify commissioning, and keep motion local to the machine. From my experience, this format is a sweet spot for packaging axes, indexing turntables, and feed mechanisms where repeatability matters and cabinet space is tight. You might notice that the “85” points to the 85 mm frame size, and the “3S” typically indicates a higher‑torque multi‑stack build—useful when you want stronger holding torque without moving up to a separate servo+drive.

Company’s Order Placement Process and Guarantees

• Lead time: 1 week for in‑stock items; no more than 1 month at the latest
• Payment terms: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• Integrated motor + drive: Reduces control cabinet footprint and wiring, which typically lowers installation time and points of failure.
• NEMA 34 (85 mm) frame: A robust size for conveyors, indexing plates, and medium‑load actuators needing extra torque headroom.
• Local motion control: Supports common command modes (e.g., pulse/direction and discrete I/O), easing retrofit work on existing PLCs.
• 24–48 VDC operation (typical): Easy to power from standard industrial DC supplies; simpler safety architecture for low‑voltage systems.
• Reduced cabinet heat: Drive electronics live on the motor, so in many cases you’ll see lower panel thermal load and fewer fans.
• Clean wiring concept: Short motor leads and compact I/O connectors help minimize electrical noise on fast‑moving equipment.

Technical Specifications

Application Fields

You’ll typically see the ILS1B853S1456 on compact machines that need steady torque and position repeatability without the overhead of a separate drive:

• Packaging and labeling lines (indexing tables, pick‑and‑place, film feed)
• Electronics assembly fixtures (screwdriving axes, test positioners)
• Lab automation and light process equipment (valve actuators, sample handlers)
• Small conveyors, feeders, and metering augers where speed changes are frequent

A customer in food packaging told us the integrated format “cleaned up the cabinet and shaved a day off commissioning,” mainly because they eliminated long motor leads and tuning a separate drive.

Advantages & Value

• Reliability: Fewer interconnects usually mean fewer intermittent faults on moving axes.
• Compatibility: Works well with common PLCs via pulse/direction; fieldbus options exist across the ILS range if you standardize on CANopen.
• Cost control: Integrated electronics can reduce cabinet size, cable trays, and labor—savings add up across multi‑axis machines.
• Support: In most cases, Schneider Electric tooling and documentation are straightforward, and firmware utilities help keep motion profiles consistent across units.

Installation & Maintenance

• Mounting: Rigidly mount to a flat surface using the NEMA 34 bolt pattern. Align couplings carefully to avoid bearing load.
• Power & wiring: Use a regulated 24–48 VDC supply sized for peak current. Shield pulse/direction lines and keep power separate from signal routing.
• Cooling & enclosure: Provide airflow around the motor body; if installed inside a cabinet, ensure ventilation. Derate at elevated ambient temperatures.
• Safety: De‑energize before connecting or changing I/O. Implement E‑stop circuits upstream of the DC supply.
• Routine care: Check connector tightness, clean dust from fins, and verify homing sensors periodically. If configuration software applies, keep parameter backups and update firmware only when validated.

Recommended Supporting Components

• 24–48 VDC power supplies: Schneider Electric ABL8 series (for example, ABL8MEM24050 for 24 V/5 A) to match your axis load.
• Shielded signal cables: M12/M23 industrial cordsets for pulse/direction and I/O, with proper grounding to reduce noise.
• Planetary gearboxes: NEMA 34‑flange gear reducers when you need higher torque at lower speed.
• Line reactors/EMI filters: Useful in electrically noisy panels to stabilize DC bus and minimize interference.

Quality & Certifications

• Certifications: CE and RoHS compliance are typical for Lexium ILS integrated steppers; UL recognition may apply by sub‑variant.
• Manufacturer’s warranty: 365‑day warranty as supplied by us for this item.

If you want us to confirm torque curves or the exact interface pinout for ILS1B853S1456 before ordering, send your required speed/torque point and control method. We’ll verify the sub‑variant and propose a matched power supply and cables so the axis runs right the first time.
