Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The ILS1V851PB1F0 is a Schneider Electric Lexium integrated drive stepper motor, combining a 3-phase stepper motor and drive electronics in a single housing. It runs on a 36 V DC single-phase supply, delivers 2 Nm holding torque, and includes a holding brake. The unit is rated IP41, carries CE marking, and is designed for flange mounting. The integrated drive accepts pulse/direction commands at 5 V without RS422, making it a direct-fit for step-and-direction controllers common in positioning tables and pick-and-place cells. The 2 Nm holding torque (17.7 lbf.in) suits medium-duty indexing applications, and the holding brake holds the load when power is removed — no external brake resistor needed. Rotor inertia is 1.3 kg.cm², and the feedback is an index pulse for homing sequences. The drive includes protection against overload, short circuit of the output voltage, and safe torque off. Positioning accuracy is rated at +/- 6 arc min, which is typical for a stepper without encoder feedback — adequate for many conveyor and rotary indexing tasks but not for closed-loop servo precision. The shock rating of 150 m/s² over 1000 shocks per EN/IEC 60068-2-29 confirms the assembly can survive transport and moderate machine vibration. ## Applications Lexium integrated drives of this class are used in packaging, labeling, pick-and-place, and small assembly machines where a compact, single-cable motion axis is needed. The integrated drive eliminates a separate drive cabinet and reduces wiring, which suits OEMs building modular or mobile equipment. The holding brake makes it suitable for vertical-axis applications where the load must not drop on power loss. Within Schneider's Lexium integrated drive family, the ILS1V851PB1F0 sits as a 36 V DC variant with a holding brake, targeting applications that need a compact, self-contained motion axis with fail-safe load holding. It is specified by machine builders who want to reduce panel space and cabling compared to a separate drive and motor combination. ## Pricing & sourcing The ILS1V851PB1F0 is a current-production Lexium drive, normally sourced to order.
