Schneider Lexium MDrive: Motion Control

Lexium MDrive: Motion Control

Schneider's Lexium MDrive® Motion Control models integrate a high-torque 1.8° 2-phase stepper motor with on-board I/O and fully programmable motion controller, drive electronics, and closed loop performance with internal encoder option. This means Lexium MDrive Motion Control products are stand-alone motion control solutions that can be used without an external controller.

For operation in harsh environments, IP65-rated Lexium MDrive products with industrial M12 circular connectors are sealed against water and dust ingress, excluding motor shaft. Price decreasing in 2015 makes additional environmental protection more affordable for all applications.

Lexium MDrive Motion Control products (LMD_M) have an RS-422/485 serial interface. Programming is with MCode, simple 1 to 2 character instructions, using the Lexium1 MDrive Software Suite provided free of charge.

Lexium MDrive Motion Control closed loop products (LMDCM) are equipped with 1000 line (4000 count/rev) encoders internal to the unit, requiring no extra space in an application. Encoders perform stall detection, position maintenance and find index mark, in addition to monitoring motor shaft position for real time closed loop feedback accomplished with hMTechnology.
