Overview
The ILS2K851PC1F0 is a Schneider Lexium integrated drive combining a 3-phase stepper motor and drive electronics in a single housing, order code ILS2K851PC1F0, rated for 24 V DC supply and delivering 2 N.m of holding torque. It carries 6 poles, a holding brake, and an IP41 enclosure, with CE marking and compliance to EN 61800-3 for second-environment industrial use.
As an integrated stepper drive, the ILS2K851PC1F0 eliminates the separate motor and drive cabling by embedding the drive electronics onto the motor frame. The 2 N.m holding torque defines the static load it can maintain at standstill — sufficient for positioning axes in pick-and-place or labelling stations without external brakes. Communication is via Ethernet/IP and RS485 Modbus TCP at 9.6, 19.2, and 38.4 kbaud, allowing direct connection to a PLC or motion controller over a standard industrial network. The integrated index pulse feedback provides position confirmation at 20000 points per turn, giving a rated accuracy of +/- 6 arc min. Protection circuits cover short circuit and overload of the output voltage, plus Safe Torque Off (STO) for safe stop in emergency-stop chains. The rotor inertia of 1.3 kg.cm² influences acceleration and deceleration profiles — relevant when tuning move times for high-cycle applications.
Applications
The ILS2K851PC1F0 is used in machine automation where a compact, single-cable stepper axis is needed — typical on packaging machines, assembly cells, conveyor diverters, and small pick-and-place gantries. The integrated drive reduces panel space and wiring time compared to a separate drive and motor pair.
The ILS2K851PC1F0 carries CE marking and is designed to EN 61800-3:2001 for second-environment industrial installations, with additional compliance to IEC 60072-1, IEC 50178, and IEC 50347. The holding brake and STO function are integrated; no separate safety relay is required for basic safe stop. Sourcing is via RFQ — confirm current lead time and minimum order quantity with the distributor.
