Overview
The ILS1M851PB1A0 is a Schneider Electric Lexium integrated drive, combining a 3-phase stepper motor and drive electronics in a single flange-mount package rated at 2 N.m torque and 36 V DC supply. It carries 6 poles, runs on single-phase input, and is protected to IP41 for in-cabinet use.
This integrated drive accepts a 36 V DC supply and delivers up to 2 N.m holding torque through a 3-phase stepper motor with 6 poles. The rotor inertia is 1.1 kg.cm², and the winding is configured for medium speed and medium torque applications. Feedback is via an index pulse, and the motor achieves an accuracy of +/- 6 arc min. The drive section provides 4 signals that can each be configured as input or output, with an output voltage range of 10...30 V DC. Communication is over RS485 at 9.6, 19.2, or 38.4 kbaud, and the integrated I/O handles motion sequencing without an external PLC for simple point-to-point moves. Protection includes safe torque off, overload of output voltage, and short circuit of the output voltage. The unit is rated for 150 m/s² shock over 1000 shocks per EN/IEC 60068-2-29, and complies with EN 61800-3:2001 for second environment (industrial) EMC. Natural convection cooling keeps the design simple, and the printed circuit board connector simplifies wiring.
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 separate motor and drive cabling, saving panel space and reducing installation time on multi-axis machines.
The ILS1M851PB1A0 sits in the Lexium integrated drive range as a medium-torque, medium-speed stepper option. It is specified by machine builders who want a pre-matched motor-drive combination with RS485 networking, rather than assembling a separate stepper drive and motor from different families.
