Overview
The ILS2T851PC1F0 is a Schneider Lexium integrated drive combining a 6-pole single-phase stepper motor with an onboard drive, rated at 22 W continuous power and 2 N.m holding torque on a 24 V DC supply. 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.
