Robust Lexium MDrive® Motion Control products integrate 1.8° 2-phase stepper motors with control electronics. Included are on-board programmable motion controller for stand-alone operation, and optional hMT closed loop performance.

Feedback options include open loop, or closed loop with a 1000 line (4000 counts/rev) incremental or multi-turn absolute encoder. Both encoder options feature hMT closed loop performance.

This high degree of integration can reduce machine complexity, size and cost in many stepper and servo motor applications. Lexium MDrive delivers exceptional performance and smoothness with advanced current control. Ideal for machine builders who want an optimized motor with on-board electronics, Lexium MDrive products are well suited for industrial applications.

Communications interface

The LMDxM uses an isolated RS-422/485 communication interface with selectable BAUD rate ranging from 4.8 to 115 kilobits per second via a standard 9-pin D-subminiature connector. An optional USB to RS-422/485 Comm converter with cable is available and is compatible with all 32 and 64 bit operating systems.

Power and I/O

DC power and the I/O are interfaced via robust locking connectors: a 2-pin screw lock connector for power, and a pair of 7-pin spring-clamp terminal blocks with side-locking tabs for I/O.

The Lexium MDrive NEMA 17 (42 mm) has a DC input power range of +12 to +48 VDC.
The isolated I/O bank consists of Three (3) +5 to +24 VDC inputs, 12-bit analog input, and One (1) 5.5 mA high-speed signal output

The Lexium MDrive NEMA 23 (57 mm) has a DC input power range of +12 to +60 VDC. The power input is protected against over-voltage.
The isolated I/O bank consists of Four (4) +5 to +24 VDC inputs, 12-bit analog input, Two (2) 100mA -24 to +24V dry contact style power outputs, and One (1) 5.5 mA high-speed signal output

The Lexium MDrive NEMA 34 (85 mm) has a DC input power range of +12 to +70 VDC. The power input is protected against over-voltage.
The isolated I/O bank consists of Four (4) +5 to +24 VDC inputs, 12-bit analog input, Two (2) 100mA, -24 to +24V dry contact style power outputs, and One (1) 5.5 mA high-speed signal output

Software

The Lexium MDrive Motion Control uses the powerful and versatile MCode programming and control language. Users can take advantage of the 11, 120 bytes of flash memory and 336 user labels to write programs ranging from simple motion to complex interactions between motion, trip functions and I/O.

A powerful new Graphical User Interface (GUI), the Motion Control Programmer simplifies programming, simulating and debugging MCode application programs.
