Overview
The ILS2T851PB1F0 is a Schneider Lexium integrated drive combining a 3-phase stepper motor and drive electronics in one housing, rated for 48 V DC supply and delivering 2 Nm of holding torque. It carries 6 poles, an integrated Modbus TCP interface, and a holding brake, all within an IP41-rated flange-mount package. The unit is CE marked and complies with EN/IEC 61800-3 for EMC in the second environment, making it suited for industrial machine cabinets where conducted and radiated emissions must be controlled.
As a closed-loop stepper system, the ILS2T851PB1F0 uses an index pulse feedback type to maintain position accuracy within ±6 arc minutes, with a rotor inertia of 1.3 kg·cm² that influences acceleration and settling time in point-to-point moves. The integrated drive accepts 48 V DC and Modbus TCP commands at 9.6, 19.2, or 38.4 kbaud over RS485, with four configurable signal lines that can serve as digital inputs or outputs. The holding brake is built in, eliminating the need for an external brake resistor on vertical loads or when power is removed. Protection covers overload and short circuit of the output voltage, plus Safe Torque Off (STO) for controlled stop in safety circuits. Natural convection cooling keeps the design simple, with no fan to fail.
Applications
Lexium integrated drives of this class are specified in packaging, labeling, pick-and-place, and small assembly machines where a compact motor-drive package saves panel space and wiring. The 48 V DC supply suits battery-backed or low-voltage environments, and the Modbus TCP interface integrates directly with PLCs and HMIs without a separate motion controller.
The ILS2T851PB1F0 carries CE marking and complies with EN/IEC 50178, IEC 60072-1, EN 61800-3:2001, and EN 50347. No lifecycle status (active, NRND, or discontinued) is listed in the available evidence; an RFQ is the recommended path to confirm current production status and lead time.
